FROGS OF COLOMBIA — COCHRAN AND GOIN 355 



lar ridge encircling upper part of tympanum; skin of throat and chest 

 very finely granular; that of belly and lower surface of thigh uniformly 

 and a little more coarsely granular; a distinct skinfold across chest; 

 adult female, no vocal sac. Skin of head not co-ossified with skull, roof 

 of skull not exostosed. 



Dimensions. — Head and body, 38 mm.; head length, 10.8 mm.; 

 head width, 12.5 mm.; femur, 19.9 mm.; tibia, 21.9 mm.; heel-to-toe, 

 16.8 mm.; hand, 11.7 mm. 



Color in alcohol. — Uniform yellowish white above and below except 

 for a narrow chocolate stripe along each canthus from tip of snout 

 to eye. 



Remarks. — We have examined and compared the types of Hyla 

 aurantiaca and Hyla lactea (in Museum d'Histoire Naturelle, Paris) 

 and there seems no doubt that they are conspecific, and no doubt 

 that they are the same species as occurs in Colombia. When the two 

 types were compared with fresh material from Leticia the only 

 differences we could note were those due to states of preservation. 



What little is known of the life history of this species was sum- 

 marized by Goin (1957, p. 27). 



Myers and Leviton (1961, p. 61) pointed out that the correct 

 generic name for this group is Sphaenorhynchus Tschudi. 



In life these frogs are pale green with the ulnar ridge, tarsal ridge, 

 and anal flaps white, with light yellowish dorsolateral stripes from 

 eye to groin and with the can thai stripes a rusty red.

Diagnosis. — A large Sphaenorhynchus with tympanum somewhat 

 indistinct, vomerine teeth, and dermal flaps lateral to vent, and 

 without a dark stripe along the canthus from tip of snout to eye. 



S. dorisae can be distingushed from S. aurantiacus by the absence of 

 the canthal stripe and from S. habrus by the presence of vomerine 

 teeth. 



Description. — UF 8506 (holotype), from Leticia, Amazonas, 

 Colombia. Head moderately broad, its width about equal to distance
