and fifty-six; iirosteges, seventy-iiiue. In the specimen with twenty- 

 tliree rows of scales, tlie length of the tail enters the total four and two- 

 sevenths times; in the one with twenty-one rows, it enters four and one- 

 tenth times. 



Color everywhere black, except on the chin and throat and on tlie 

 inferior side of the tail. The former was reddish in life. There are 

 very faint traces of stri])es on the secoiul, third, and fourth, and on the 

 median dorsal rows (»f scales. Marks of the lateral stripe are more evi- 

 dent on the fourth than on the second rows of scales. No traces of 

 spots on tlie i)arietal scuta. 



This species is allied to the U.elegans, from which it differs in its two 

 l)reocular plates, iu the position of the lateral stripes, and, supposing 

 the individuals to be adult, in its small size. The color is difi'erent 

 from that of any of the forms referred to that species.

Collection of K. D. Cope. 



I took the specimens described on the shores of Klamath Lake, Oregon. 

 Their sluggish movements contrasted strongly with those of the more 

 active U. sirtalis parictulis, which is abundant at the same locality.
