Sullivi 1949 Rhyacotriton olympicus -2- Aug 24 French Camp, 3/00 ft., Humboldt Co., Calif. - 2 small individuals taken from among loose pebbles - by digging in them - along the stream below camp (see found p 198), about 100 yards down hill from the streams source. The situation is one of moss covered rocks, a small but probably permanent stream, bordered by Five-finger Fern Adiantum pedatum and overhung by nine-bark Pseudocarpus capitatus and alders, also western azalea close along the borders - in a very open Douglas Fir forest with Tan Oak- Chinquapin - Madrone understory. Dicamptodon A much larger individual was taken about 50 feet further downstream under a moss covered flat rock in the waters of a very small pool (3ft long by 1 foot wide by 6 inches deep). Water temperature of this stream is 51 F. Aug 27 Maple Camp Spring, 3/2 mi NE, Willow Creek, 2200 ft. Humboldt Co., Calif. I found 7 larvae / of which 1 nearly metamorphosed, in the small gravel under the larger moss covered rocks. This stream probably does not flow more than 1 gallon a minute, has a temperature of 54° F, and vanished completely about 8 feet below where these larvae were taken. It must not extend more than 100 yds further up hill.
