FROGS OF COLOMBIA — COCHRAN AND GOIN 395 



confined in Colombia to the states east of the Andes, in the vast area 

 drained by the Amazon's tributaries. The Colombian frogs vary in 

 about the same way as the Venezuelan paratypes at hand, some 

 having much darker markings than others, with more distinct dorsal 

 chevrons and ventral spots. The dark-encircled tubercles on shoulders 

 and top of snout are apparent in nearly all examples, however. The 

 canthus sometimes has a sharply defined dark stripe, continued along 

 the ridge encircling the upper part of the tympanum. The adpressed 

 heel sometimes reaches only to the anterior margin of eye, but often 

 to beyond the tip of the snout. 



The Venezuelan paratypes of this frog tend to have somewhat 

 longer legs than their Colombian counterparts. In other characteristics 

 the frogs from both countries are so similar that it does not seem 

 necessary to assign another name to the Colombian population.
