29. Leptophis bocourti Boulenger. 

 Leptophis bocourti Boulenger, P. Z. S., 1898, p. 116. 



This species is represented by but a single specimen, No. 2011, which was 

 collected by Mrs. H. H. Smith at Cacagualito, Colombia (elev. 1,500 ft.). It is 

 a female. 



The specimen agrees well with Boulenger's description, except in the greater 

 number of gastrosteges and the smaller number of urosteges. The terminal shield, 

 or spine, of the tail is formed normally, yet the tip of the tail is thicker than is 

 usual in the genus. It is therefore possible that the tip has been amputated and 

 healed, and that the reduced number of urosteges of this specimen is thus accounted 

 for. The color is a uniform, very dark green on the upper surface, without the 

 dots and lines which Boulenger describes; light green below, except the lower jaw, 

 which is yellow, with a green border covering about half of the lower labials.
