spots on the sides ; a white hne from the end of the snout 

 extends beneath the eye and ear nearly to the arm insertion ; 

 below dark slate color, the scales on the abdomen margined 

 posteriorly with black. 



Total length, 115 mm.; length of head and body, .45 mm.; 

 length of head (to ear), 10.5 mm. 



Notes on Paratypcs: The most variable character is the 

 number of rows of scales around the body, this number vary- 

 ing from 31 to 39. This variation seems to be associated with 

 differences in the number of small lateral scales. The enlarged 

 scales on the occiput are differently arranged and vary in 

 size, but a common grouping is a large scale on each side of 

 a small one followed by two large ones. The head shields are 

 rugose or striated in all specimens. The preanals are two, 

 except that in two specimens there is a long, narrow scale on 

 the outer side of each large one. TJsually the supraoculars 

 are two, of which the first is the larger and in contact with 

 the prefrontals. In two specimens there are three supraocu- 

 lars on each side, the first the largest and in contact with the 

 prefrontals ; in another, the type, a small one is, on one side, 

 interposed between the large one and the prefrontal. The 

 two dark brown or black stripes may begin at the tip or on 

 the base of the snout and are generally separated from each 

 other by the width of two or two and a half scales. The 

 stripe between the black ones is generally wid-^r on the head 

 and neck and is often paler than the ground color of the body. 

 The black stripes are irregularly defined below, and there are 

 usually present some black spots on the flanks which may rep- 

 resent a band between the axilla and groin. The white lin-?
