614 ZOOLOGY— REPTILES AND BATRACHIANS OE ARIZONA. 



This species, originally described from Coahuila, Durango, and the Gila 

 River, was found to be quite common at Fort Whipple, where numerous 

 specimens were observed besides the few transmitted to Washington. It 

 grows to a large size, equaling or surpassing E. sirtalis in this respect, but 

 preserving its very slender form, which, with the strong, clear stripes, ren- 

 ders it an attractive object, The larger animals, which I kept in confine- 

 ment, were quite savage when first caught, biting when taken in hand, and 

 even acting sometimes on the offensive when irritated ; but they usually 

 became gentle and submissive after a little handling.

As in E. macrostemma, the dorsal scales are in twenty-one rows ; but the 

 lateral stripe is on the second and third, not third and fourth. There are 

 eight superior labials, of which the sixth and seventh are very large, being 

 hiffher than wide, one of them extending above the lower level of the eve. 

 The color is a light olive-brown, or ashy-brown ; the head indifferently 

 brown or black on top. The bands are narrow, xinmargined ; the dorsal one 

 strong ; the lateral ones less distinct ; and there are two series of small, black, 

 lateral spots, which encroach at regular intervals upon both the longitudinal 

 bands. 



This species appears to merit its name, since, unlike several others of 

 local distribution, it is widely dispersed in the West, My latest investiga- 

 tions carry its range to the northern borders of Dakota and Montana, and even 

 a little beyond the watershed of the Missouri, into that of the Saskatchewan, 

 as I found it in the summer of 1874 at Chief Mountain Lake, latitude 49° N., 

 where it was associated with the form of E. sirtalis called E. pickeringi. I 

 also found it in a corresponding latitude farther east, along with E. radix. 

 It is a common species in various parts of Arizona and New Mexico. My 

 specimens were found along the Zuni River in New Mexico, wherever this
