especially on the lateral stripe. There are about 90 spots in each row, 

 the upper not very distinct. The belly is pale olive with small spots 

 on the ends of many ventrals. No parietal spots and the labials very 

 slightly margined. All these specimens have the small fine head, the 

 short posterior chin-shields and the yellow throat and chin of E, 

 elegans, and notwithstanding their wide difference in color, their specific 

 unity is established by the fortunate fact that specimen g was a female,. 

 gravid at the time of death, and I removed from her thirteen young, 

 twelve of which are typical elegans in color, being so dark that the spots 

 are barely visible, and corresponding exactly to specimens a. b, c, cL 

 The thirteenth is also dark, but when first taken from the mother 

 showed red markings on the flanks like those of specimen /. This red 

 has almost entirely disappeared after twelve weeks in spirits. All 

 of these young snakes have 21 rows of scales; ten have 8 labials; three 

 have 7 on one side. The temporals range from 1-2-3 to 2-3-1. We 

 have, then, unborn young exhibiting the colors of elegans B. and G. 

 and infernalis infernalis Cope, the one resembling the latter having the 

 scales and labials of elegans, contained in the oviducts of a female 

 which, differing from both in color, departs in no other way from the 

 features of elegans. If the red, which is a purely individual acquisition, 

 were omitted, specimen g would come very close to E. e. lineolata Cope, 

 some of which are referable to the present subspecies and some to E. e. 

 vagrans. 



Trcpidonotus trivittatus Hallow, is no more than a typical elegan.f 

 with 19 rows. 



E. e. elegans appears to occur only in California, from Shastha in the 

 north down to the San Bernardino moimtains, beyond which it seems 

 not to extend.

This form ranges over the higher portion of the great plains, from 

 whence it has penetrated through the valleys of the Snake and the Co- 

 lumbia rivers to the western coast. It is the garter snake of the 

 Sierras and the Rocky mountains. I have taken it at 6,000 feet eleva- 



^ Eutwnia kennicotti Jan (Arch. Zool. Anat. and Phys., Ill, 1865, p. 216), with 

 21 rows and 8 labials, may belong here, but the description is vague, and the 

 only locality given is northern United States.
