E Santa Susana, 1.5mi N and 2.7 mi E Santa [illegible] I caught on Euneces skiltoniana and a Xerhnothus multicarinatus wellii. Another skink was seen but escaped. The alligator lizard ate the skink which I captured. The lizards were found beneath surface litter near a steam bottom in sagelmb covered hills. Hyla tegula were calling from the stream. Feb. 2, 1957 Los Angeles Co., Calif Mulholland Drive, 1 mi. W Topanga Canyon Road, Santa Monica Mtme. A few minutes collecting here yielded two Uta stansburiana heesperie and one Batrachosepa alternatus. So species account on Uta.

R. Zweifel Mar 1, 1952 31 Butte Co. Calif. The Munays, Bill Bremer and I left Berkeley at 10:15 AM and arrived in the vicinity of Chico about 3 1/2 hours later. We drove to De Sable by way of the road which parallels Butte Creek. The canyon has been cut through layers of alternating sandstone and conglomer- ate which outcrop in the form of ledges. There are many springs in these outcrops so that the whole region appears, at least at this season, rather wellwatered. In the digger-pine-blue oak association 10.4 mi. 55W De Sable, we collected Sceloporus occidentalis, 2 Cnemidophorus skeletonatus and observed many Batrachoseps. The lizards were found beneath boards and logs. Just south of the road junction at De Sable, a road heads down into the canyon towards some mines. 1/4 mi. W De Sable, on this road, 4 Rana dr. bayllei were collected (see species account). Hyla were breeding in a pond. Plant associates: Douglas Fir, yellow pine, bay, canyon oak. Mar 2, 1950

R. Zweifel Napa and Sonoma Counties, California Mar. 23, 1952 33 Today with Keith and Cynthia Murray I went into the north bay area to collect Anceles for Chuck Lowe. Our first stop was at the Robert Louis Stevenson Home, Mt. St. Helena, Napa Co. One small Anieles flavignmetatus was found under a board or mud beside a water tank. We were seeing the area with just three salamanders when I turned over one last board in front of the home and found six flies under it, an adult and five juveniles. This board seemed no different from dozens of others we had already turned within a few yards of the spot. The board was resting on leaf litter, as were another board under which one more juvenile was found. In addition to the eight Anieles captured here, thus Ensating was taken and many Batrachosega seen. Driving back toward Calistoga, at 2 mi. NW Calistoga, 610', Napa Co., we noticed a tree fallen on a grassy hillside and decided to investigate the top and branches with the thought of possibly finding a ring-neck snake. When we left the area about 1½ hours later, we had taken 50 Anieles flavignmetatus, 12 A. lugubris, 1 Hyla regilla, 1 Xenorhinos micrornatus, 97 Eumeces siblonisoma, 1 Diadaphis and a Hypsoglena. The spot of collection is on a ridge

R. Zweifel Maya and Sonoma Counties, California running about south-west. Here there are a few black oaks, diggs pines and manzanitas, with a single scraggly douglas fir a couple of hundred yards up the ridge, but the aspect of the place is predominantly grassy. The logs first investigated were digger pine, from a log about 2 1/2 ft in maximum diameter. A. flavipunctatus was abundantly found under the bark and within and beneath the logs. About half the larvae were collected here; the rest found beneath rock on the adjacent hillsides. Similarly, the less common A. lugubris was found both in the logs and under rocks. Both species of Anidea were found beneath one rock. The snakes were found in the logs. Skinks were both in logs and under rocks (see again accounts). The land around here had evidently been cleared, judging both from the stumps about its hillside, and from a thick growth of douglas fir and oak surrounding a homestead about 1/4 mile down the ridge. From here we drove to the vicinity of Staggs Springs, Sonoma County. At 2.9 mi. w Staggs Springs we collected 8 Anidea flavipunctatus, 1 Eumeces and 2 Diadophis. 2.9 mi. W Staggs Springs we collected 4 larvae, 1 A. lugubris, 1 Triturus.

R. Zwift Sonoma Co., Calif. May. 23, 1952 35 saurians and 1 Diadophis. All three were found under boards. Elaphe we found both in rather moist situations by a spring and on a comparatively dry hillside The Triturus, gravid female, was under a board on a hillside about 200 feet from the stream. We did not investigate the stream for salamanders or frogs. [illegible]

R. Zweifel April 26, 1952 Journal 36 Keith and Cynthia Murray and I left Berkeley at 7:45 this morning and my lunch time was in the Sierran foothills on State Highway 80. Throughout much of the foothill region the prominent trees are oaks - Q. douglasii and Q. wislizeni - in an open to closed woodland. It looks much like typical digger-pine blue oak association but digger pines appear to be absent. We went from the oak through chaparral (where blooming redbud was much in evidence) and met the yellow pines and incense cedars at 4000' without ever seeing digger pines. Our intent was to go to Hume Lake, but the road was snowed in. We were told in General Grant Grove that there had been an eleven inch snowfall last night. Some places in this region the snow pack was 6-8' deep. There was a solid snow cover down to 5500', and scattered patches to 5000' elevation. The weather seemed to be closing in, so we went off down the mountain and have camped along State Highway 65 between Auckland and Elderwood, elevation 900'. Our campsite is in the oak-grassland region of the foothills. Today's catch added up like this: Hwy 180 at 5000': 7 Tinturns; near Pinehurst,

In a few minutes collecting before breakfast I caught 3 more skinks and a small striped racer. Keith also picked up a couple of skinks. From this camp we drove south to Porterville and then east on Hwy 190 to Camp Wisher at the end of the road on the North Fork of the middle fork of the Tulare River. Two miles east of Springville Keith caught a Diadophis which unfortunately later escaped. In a stream 8.7 mi by road ENE of Springville I caught 7 S. boylii and Keith a garter snake (conclusi) and a skink. The yellow pine - mense cedar forest is well developed downstream a little from where we collected, - it follows the Tulare River canyon down. At the collection site cotton oak, sycamore and birch are present with only two or three yellow pines nearby.

R. Zweifel April 27, 1952 38 Journal At Camp Wishon, 4000' elevation, Triturus were very abundant. We collected 23 and could have taken many more. This is in the yellow pine - some cedar forest. A single adult Rana boylii was found here. The main stream is still much too high to harbor any frogs. Since it was cold and threatening rain at this altitude, we went back down the canyon to camp at Coffee Camp Ground on the Middle Fork of the Tule River. Only a few small R. boylii were taken here. April 28, 1952 The rain caught up with us at about 2:30 this morning and made the night rather miserable for us. We broke camp early and went to Porterville for Breakfast. From Porterville we drove to White River, Glennville and Woody, camping in the oil fields between Woody and Bakersfield. We tried frog collecting in a creek near Glennville but had no luck, the water being very high. The road over the Hunger Mountain was closed, hence the route via Woody. Young Cummins gilberti collected near White River, Tulare Co. and Woody, Kern Co., are of interest in that they show no subspeciation influence, the tails being wholly blue.

P. Zweifel April 28, 1952 Journal 39 I caught a Diadeghis 3.3 mi ENE of Woody, a new southerly record for the Sierras. Batrachoseps also was taken here, as well as at other stations along one route from White River to Woody. Crotalus and Thamnophis s. coulii also were collected 3.3 mi ENE Woody. April 29, 1952 The Kern River canyon for most of its lower region is of very arid aspect, the hill sides being at best covered with sparse diggaringo and live oak. But where small creeks flow down to enter the Kern, there are local strips of mesic conditions on its mountainsides. At one of these, Stark Creek, 18 mi. ENE Bakersfield, I found an adult Ensatina under a rock. At [illegible] onohera, Cow Flat Creek, 20 mi. ENE Bakersfield, we collected a Diadeghis, 7 Smalgylls, a Herthondre multivirminative, 2 Ensatinia and several Batrachoseps. The Bats are of special interest in that they me the largest B. attenuata I recall. Yet they still look very unlike B. pacificus. We stopped for lunch at Hoho Hot Springs and thus collected along Clear Creek, Hyla regila, Cnemexa gielerti, Uta, Herthondre, and Rana boylii. One of the skinks seems to be a gielerti x subicandatu.

Ecologically, this is an area of great interest. Digger pines and blue oak are present with about the same density as in typical open pine-oak associations. But interspersed with the pines and blue oaks are numerous scrubby liveoaks, ceanothus, and a few junipers, the latter being more prominent toward the canyon mouth. The whole aspect is rather denser than the usual digger pine- blue oak woodland. Xantusia vigilis and Cnemidophorus tigris were found here. April 30, 1952 Today we went from Bodfish to Weldar and over to the desert by way of Keler Creek wash and Dove Springs to Red Rock Canyon. We went on to camp in Jawbone Canyon. The entire route from Weldar to Racador is quite arid, Joshua trees being prominent along much of the way. Particularly noticeable were the large, dark Sceloporus occidentalis which frequent granite boulders throughout the Joshua tree area. Possibly these lizards are restricted.

Our camp in Jawbone Canyon was at an elevation of about 2500' where the prominent plant in the wide, sandy canyon bottom is an Atriplex. Lancea drops out just below this point. Collected here were Crotalus viridis, Piturphicatonifis deserticola, Alla stonburnans stignegi, Salozona magister, Hyla regilla and Bufo bras. Gemelia waligoni and Xantusia vigilis were also seen. The amphithe were in muddy pools by the temporary streams in the wide canyon bottom. The Xantusia was under a piece of paper beneath an Atriplex. There are no tree yuccas near here, and very few other yuccas. We tried right driving the road in Red Rock Canyon and the road to Randolburg, but turned up only one badly mangled sidewinder, and quit after about 2 hours. May 1, 1952 We broke camp late in the morning and drove to Mojave, and from there up Tehachapi Pass and into Camoron Valley. There is a road by Oak Creek, but we were stopped by a locked gate.

The region of our route up Cameron Valley and over Oak Creek Pass is a tribute to overgrazing. The succession extends and when the wild-flowers are gone the aspect must be bleak indeed. About all there is to relieve the monotony of the greasy hills is an occasional oak-fleld draw and a few patches of Joshua trees. Oak Creek along its upper reaches would be a good bet for Rosa Boylii if one could get past the locked gate. At Bear Valley Ranch we were advised to try a Mr. Jimmy Rogers (Will Rogers's) son) who had a ranch on the opposite (north) side of her mountain and had a road fenced now by loggers) into the timber. At the Rogers' Ranch we met Mr. Jimmy Blake, cousin of Rogers, who helped run the ranch. We were immediately granted permission to collect on his land and to use his road.

Most of the rest of the way down the mountain was lightly wooded with digger pine, blue oak & live oak. Along the creek there was a much heavier stand of trees. There appears to be a good stand of timber on the mountain, but we could not make it up there to the level of the timber. By the time the car was out of the mud, it was after dark. Except for a few skinks picked up both driving up and taking down the mountain, we collected little here. We drove until about midnight, making camp at Fernclmont Flat on the Ridge Route, Los Angeles County. There was a mixed chorus of Hyla regilla and H. arenicolor here, when heard together, the two calls are quite distinctive, Regilla with its disyllabic croak and arenicolor with its mono- syllabic "quack".

R. Zweifel May 30, 1952 Journal 47 Bill Breiner and I left Berkeley at 7:20 AM and arrived at Butte Meadows, Butte Co., about 12:30 PM. Both Rana cascadae and Rana boylii series have been recorded from Butte Meadows, so I was particularly eager to collect here. We spent about two hours at Butte Meadows but could find no Rana. The chief stream of the region, Big Butte Creek, was well over its usual banks and carrying much water. Small streams wandering through the meadows were searched for frogs, as was Big Butte Creek, but only a single Hyla was found. Probably these smaller streams are not permanent. The weather was warm & sunny, but there were patches of snow in sheltered parts of the forest. Yellow pine, Douglas fir, white fir and incense cedars are the dominant trees here. The general aspect of the region is that of the mid-Arid Transition zone. Jensenville, Butte Co., about 5 miles NE Butte Meadow, is another R. cascadae locality, but here we could find no frogs either. The vegetation here is different, having a higher zone aspect. Lodgepole pine, Jeffrey pine and white fir dominate here, with a very few yellow pine present. It may be that this particular association is

At Butte Meadows the following were taken: 1 Thamnophis elegans , 1 Nerthistius cerulens, 1 Triturus troosa creina, 1 Ensatina eschscholtzii platensis and 1 Hyla regilla. Scelozoma graciosa was abundant. Tonight's camp is near Seneca, on the North Fork of the Feather River, Plumas Co. May 31, 1952 This morning we worked along the stream fs about ten home but could find no frogs. The stream was quite high, and thus seemed to be not good tributaries. Rana boylii may not occur in those large streams where there are no small tributaries of appropriate gradient, but it will be necessary to check again when the waters is low. Triturus t. creina, Sceloporus graciosa, S. occidentalis and Thamnophis elegans were collected here. Plants: Big-leaf maple, douglas fir, black oak, dogwood (both creek & pacific), choke cherry, thimble berry, alder, incense cedar, black cottonwood. yellow pine present as hillside, but not in canyon bottom.

We had been told that there were "bullfrogs" in the lake, but we didn't find any. 0.6 mi S Glenville we investigated a streamside pond and found in it a large number of Ambystoma macrodactylum larvae. Bullfrogs were present here. This is in the yellow pine-Douglas fir forest. From Glenville we drove via Insmile to Maford and the south over the divide to Lost Chance Cr. Rare Axylis longi were found here where the creek flows through a broad, sage- brush-covered valley. The nearest trees to the stream are the yellow and Jeffrey pines bordering the valley, at the closest 1/6 mile away. Five adult frog and 23 juveniles were seen.

About half the number were associated with a fallen digger-pine, either on the rotten log, under back, or beneath the logs on the ground. The remainder were beneath rocks. Aneides lugubris was greatly outnumbered here, only 12 being found - these too were equally distributed between logs and rocks. On one occasion, 2 lugubris and one flavi were found under the same rock. The locality of capture is on a ridge trending south-westward into the north end of the Napa valley. The immediate site of collection is a grassy hillside spotted with a few black oak, manzanita, and digger pine. A single douglas fir is mixed in with oaks and manzanita about 200 yards up the ridge, and about ¼ mile down the ridge there is a homestead surrounded by Doug firs and oaks. Probably before the land was cleared this spot was in the marginal area where the fir forest meets the digger pines. The temperature at the site of collection in one of the logs was 14.2°C

SE Livermore Alameda Co., Calif. 8 small frogs were collected and about 20 more seen in a stream which flows into Arroyo Mocho from the north. The stream is 4 feet wide at the widest and one foot dep. The gradient is sufficiently steep that rapids or small waterfalls occur every few feet for much of the course. Water temperature was 19°C. The eight frogs agree generally in dorsal pattern - many faint 2-3mm spots on greenish-brown background. The spots are slightly darker than the background. Lateral barring is indistinct. Dark throat markings are present, but not as well defined as in the north coast frogs.

R. Zweifel April 12, 1952 78 Rana boylii boylii Waddell Creek, Santa Cruz Co., Calif. 1756 R. Zweifel A single small juvenile was found, along with an adult R. aurora, in an inch wide trickle of water by the roadside in the redwood-doug fir forest. Bill Biemer spent much time hunting Triturus along the main stream and saw no Rana boylii, nor did I see any there. The weather was cold and foggy today. Where do the frogs go in this sort of weather?

R. Zernyfel April 11, 1952 79 Ron Laughlin Laughlin 3 mi NW Cool, El Dorado Co., Calif. 566-571, Joe Norman One adult & and five young. In light phase no throat pattern is discernable, but in dark phase the pattern of vermiform spots is evident. The adult female is pale reddish-tan with no pattern discernable on the back. Even the tibial bars are faint. One of the young is very similar to the adult. Two others are darker brown, with contrasting reddish lateral folds but little dorsal pattern. Another is dark greenish-brown with diffuse spotting visible on the back.

R. Zweifel April 27, 1958 Page longleaf longleaf 3.5 mi. NW Woodlake, Tulare Cr., Calif. 1790, & R. Zweifel Habitat area - small stream, flowing portion not over 3' wide, forking to 6' wide, seldom more than 6" deep. Water temperature at 9:15 A.M. 14.8 °C. Trees along the bank are as Q. wislizenii, Q. douglasii, Q. lobata (uncommon), Sambucus, Populus fremontii, Alnus incana. For the most part the stream banks are grassy to the water edge, very little in the way of sandy banks. Although the stream gradient is not steep, there are many large, angular granite rocks (as to 3' in diameter) in the bed. Stream transport is obviously not responsible - sites washed out or place so called downhill. 'Sycamore and willow present a few hundred yards downstream from where the first frog and three insects were taken.'

Rana boylii boylii Frogs collected between April 26 and May 1 A total of 30 frogs were obtained at the following localities: 8.5 mi NW Woodlake, Tulare Co. (2); 8.7 mi ENG Springville, Tulare Co. (7); Camp Wishon, Tulare Co. (1); 5 mi ENE Springville, Tulare Co. (5); Cow Flat Creek, Kern River Canyon, Kern Co. (5); Clear Creek, Hobo Hot Springs (1); Caliente Creek, 6 mi EST Caliente (7); Tschachapi Creek, 6 mi NW Tschachapi (2). On a group, these frogs are all remarkably similar. When in dark phase, the throat markings are large and dark (see drawing on next page). Dark but diffusely bounded dorsal spots are present and the tubia is distinctly barred. The light head stripe is evident when the frog is on dark phase, but scarcely visible in light phase. There is a wash of yellow in the groin and the back of the femur is orange-yellow. This yellow and yellow-orange is seen in two living frogs from Tulare Co (R.b. boylii) which however have no strong black marking in the groin, as seen in the southern Series Frogs (see drawing, next page).

This is in a broad, sagelands-corned valley with yellow and jeffrey pines on the surrounding slopes. The stream average 15' wide and 3'deep, temp- sature near edge 20.2°C. The stream banks are for the most part grassy or muddy, with occasional sandy base. The frogs was not restricted to any particular type of bank. There are no trees bordering the stream we as far at least a mile or two up a downstream. Juveniles were extremely abundant; many more could have been secured. Not adults been seen secured. There were very few snakes in the stream.

R. Zweifel Oct. 5, 1932 89 Rana boylii boylii Muck Ck., 6.3 mi. SE Clayton, Contra Costa Co., Calif. Since my last visit here, number of cattle and horses have invaded the area, with the result that most of the grass and cattails along the stream bank have been trampled. The change in the character of the stream border has affected R. aurora more than R. boylii. 10 adult boylii were taken and young were very numerous. Only four aurora were collected and a few others seen. At one spot there was a pool 4' deep with a little aquatic and riparian vegetation around it. Two large aurora were taken from the pool, and at least two others were present. At the shallow end of the pool there was a sunny, sandy bar on which several adult boylii and numerous young were found. The habitat segregation holds, even though the frogs were only about 10-12' apart.

R. Zweifel June 15, 1953 94 Rana boylii sierrae Camp Cornell 4000' Calaveras Co., Calif. Seven frogs were taken from what I consider an ideal Rana boylii stream. The stream is swift running, average 12-15' in width and has a few pools up to 2 1/2' deep. Some places where the stream is on bedrock, there are sloping banks of the granite bedrock, or which the frog were found. At other places they were on the sandy or rocky shores, or as rocks in the stream. This is an typical Season Transition Life-Zone forest. Trees present include incense-cedar, Douglas-fir, yellow pine, sugar pine, white fir, black oak and alder. All exhibited the typical "sierra-stripe" when caught. In some, the yellow of the ventral surface looks very much like that of R.b. boylii, but tends to be evenly distributed over the ventres (except the throat), not concentrated on the grain.

All were found under rocks 40 - 100 feet from a small stream. The general aspect of this locality is one of grassy, oak-studded hillslides with prominent granite outcroppings. Oaks present include valleyoak, interior liveoak and blueoak. Willows and cottonwoods are along the stream. Elevation 900'. The oaks for the most part do not form a continuous canopy.

H. Zweifel May 30, 1952 104 Serhometus coeruleus Butte Meadows, Butte Co., Calif. Adult Lygaeids collected here are remarkable for their green dorsal body surfaces. A very small juvenile has the normal bronze dorsal fond and a medium sized individual shows some yellowish-green in the region of the lateral fold but the adults have what seems at least like two large specimens a light green dorsal ground color. In the adults, the posterior portion of the head and the cape are gray, contrasting with the green body. The snout is green. One of these Lygaeids was found under a piece of wood by a small stream. When jarred, the living jumped onto the stream and swam half way across (the stream was about 4 feet wide and 4" deep) whereupon it dove to the bottom and hid under a rock with only the head and tail protruding. It stayed under water for 3 minutes before sticking its nose above the surface. Yellow pine, white fir, Douglas-fir and incense cedar are the dominant trees here.

P. Zwickel Mar. 29, 1952 Hypsiglena torquata muchulata 147 2 mi. NW Calistoga, Napa Co., Calif. 1738 R2 Found in the middle of a rotten digger pine log, elevation 610', on a ridge at the north end of Napa Valley. This is in the area where the digger pine & Douglas tire meet without benefit of a yellow pine buffer zone. The exact location is on a grassy slope beside a black oak or an oak, digger pine and monzantia studded hillside. About 1/4 mile down the ridge there is a homesite surrounded by douglas fire and oaks, probably indicative of the natural vegetation of this ridge. There is a single scraggly doug fir 200 yards up the ridge from the snake locality, in the midst of the digger pine and oak. On the same 10' x 1' log which held the Hypsiglena were no Diadophis, 3 Ancistrus laevis and a small Herkasta multicarinata. Dozens of Ancistrus flavipunctatus were taken from ad- jacent logs. Dorsal ground color: Drab (Redgwing) Neck band close to Mummy Brown Dorsal blotches close to Olive Brown.
