Diagnosis. — A hylid tree frog with rounded sacral dispophyses, 

 an inconspicuous tympanum, and the vomerine teeth in transverse 

 series which usually lie well behind the posterior margins of the 

 small, rounded choanae. 



Hyloscirtus bogotensis may be separated from the species of Crypto- 

 batrachus by the absence of a distinct tympanum; from the species of 

 Hyla it may be distinguished by the absence of a distinct tympanum, 

 by having the diapophyses of the sacral vertebrae essentially rounded, 

 and by usually having the vomerine teeth in transverse series behind 

 the choanae. 



Description. — MLS 160, from Chipaque, Cundinamarca, Colombia. 

 Vomerine teeth in two transverse series which are slightly more 

 anterior medially, lying close together behind the level of the small, 

 rounded choanae; tongue three-fourths as wide as mouth opening, 

 broadly cordiform, its posterior border slightly free and slightly 

 notched. Snout moderate, somewhat U-shaped when viewed from 

 above, tip somewhat rounded in profile, the upper jaw extending 

 beyond lower; nostrils lateral, slightly projecting, their distance from 



Figure 37. — Hyloscirtus bogotensis: CNHM 81916, male (at left), and MLS 160, 



female (both same size).
