Hendrickson 1950 Journal Left. 7 Stubly Spring, 4500 ft., Riverside Co., Calif. distinct absence of exclusive territoriality. The temperature 6" above the sand was 21.2°C. One animal collected had a temperature of 25.2°C.; the sand on which it was shot was 20.0°C. (overcast at the moment). Went up to vicinity of spring and worked intensively over the area of the tank, seep willow tree, and ridged exposed rock just above the tank. Found 1 Crotalus mitchelli, 1 small Bufo punctatus, and 1 sheep jaw on the exposed rock just above the tank; nothing more. Under the large willow is a sort of bowl about 10 ft. in diam. containing a thick litter of leaves, rotted limbs, etc. Looks ideal for skinks and amphibs., but intensive search revealed none. The big tank and its low troughs contain tadpoles; on one of the larger metamorphosing tails, I noted the characteristic red punctate markings of Bufo punctatus. Many dragon- fly larvae were seen in this water also; one was eating a tadpole. About 25 yards below the large tank collected a Crotalus mitchelli (see species account).
