griffin: ophidia from south America in carnegie museum 203 



56. Clelia euprepa sp. nov. (Plate XXVIII, figs. 7-9.) 



Thirteen solid maxillary teeth followed after a short space by two slightly 

 enlarged grooved fangs. Eye large, its length three-fifths to two-thirds of the 

 distance from the eye to the tip of the snout. Snout broad, rounded, scarcely 

 projecting beyond the lower lip. Rostral one-half as deep as broad, the portion 

 visible from above one-half or less the length of the internasal; internasals two- 

 thirds as long as the prefrontals; frontal once and a third as long as wide, pentagonal, 

 longer than its distance from the end of the snout, shorter than the parietals; loreal 

 once and a half to nearly twice as long as deep; one preocular, just reaching the 

 top of the head, separated from the frontal; two postoculars; temporals 2, 3 (2, 2 

 on the left side of No. 109) ; eight upper labials, the third, fourth, and fifth bordering 

 the orbit. The third upper labial touches the edge of the orbit by its corner only. 

 Nine lower labials, four in contact with the anterior chin-shields, which are longer 

 than the posterior. 



Nineteen rows of scales; anal undivided; gastrosteges 225-230; urosteges in 

 94-105 pairs. 



The body and tail bear narrow, irregular black rings, separated by narrower 

 white spaces which are probably bright red in life. The outlines of the black 

 markings are extremely irregular, many being united by diagonal black bars, while 

 others are broken along the back. Very few of the ventral shields of the dark rings 

 are completely black, the color extending half or two-thirds across a shield and 

 then stopping abruptly. Most of the light dorsal and lateral scales are tipped 

 with brown. The scales of the upper surface of the head and the lower labials are 

 black in the center with light (red ?) edges. A large white (red ?) spot crosses the 

 nape just behind the parietals. 



Type, C. M. No. 109; paratype, C. M. No. 108. 



The Museum possesses two males of this species, collected by Jose Steinbach 

 at Santa Cruz de la Sierra, Bolivia, and numbered as above.
