57. Clelia peruviana sp. nov. 



Eleven subequal solid maxillary teeth followed after a short space by two 

 slightly enlarged grooved fangs. Eye small, two-fifths as long as its distance from 

 the end of the snout. Snout rounded, scarcely projecting beyond the lower lip. 

 Rostral two-thirds as deep as broad, the portion visible from above equal to the 

 suture between the internasals, not quite one-third the distance between it and 

 the frontal; internasals one-half as long as the prefrontals; frontal once and one- 

 fifth as long as broad, as long as its distance from the end of the snout, a httle 

 shorter than the parietals; loreal once and two- thirds as long as deep; one preocular, 

 separated, but not widely, from the frontal, and reaching the upper surface of the 

 head; two postoculars; temporals 2, 3; eight upper labials, the fourth and fifth 

 entering the orbit; four lower labials in contact with the anterior chin-shields, which 

 are longer than the posterior. 



Scales in 19 rows; anal entire; 179 gastrosteges; 70 pairs of urosteges. 



Top of the head orange, with a dark patch on the frontal and parietals. The 

 back and sides of the anterior third of the body are uniform black. Back of this 

 the body is marked by broad black rings separated by narrow light (red?) spaces 

 in which each scale is tipped or margined with black. The black annuli are a little 

 narrower below than above. In the posterior part of the body and tail the lower 

 surface is almost entirely black. Passing forward, the black color becomes limited 

 more and more to the posterior margins of the ventral shields. The gastrosteges 

 of the anterior quarter have only their outer edges black-margined. The under 

 surface of the head, the lips, and the throat are uniformly yellowish. 



The type (C. M. No. 377) is unique. It is a male, and was collected at Tarma, 

 Peru, by Miss Lola Vance, who neglected to give the date of capture.
