Records of Pleistocene Reptiles from California

Abstract

beneath the log, and presumably the burrow served as a den for these snakes. The body lengths and total lengths of these four females ranged from 62 and 80.4 cm. to 66.5 and 85.8 cm. Of five individuals recorded with food, two had eaten Bufo b. boreas, two had fed on Pseudacris nigrita triseriata, and one contained fish bones. Thamnophis elegans vagrans (Baird and Girard).-This gartersnake was found less frequently along the stream flood plains than was the former species; however, both species were found together near pools and marshes. Unlike the red-sided gartersnake, it occurs out on the flats, at long distances from water, and was taken along the base of talus slopes at the foot of the mountains. One individual was taken by funnel trap 200 yards back from the lake shore in the dense coniferous forest at the foot of the Tetons. Two gravid females were captured while sunning themselves on the rocky, bushy side of a glacial moraine. The body lengths and total lengths of the two females were: 61.2 and 78.9 cm. for one, and 67 and 86 cm. for the other. Of the five individuals that contained food, two had eaten leeches, one had eaten a Pseudacris nigrita triseriata, one a Bufo b. boreas, and one a small fish (Cottus sp.). at the log, and presumably the burrow as a den for these snakes.
