cinnamon rufous posteriorly, and with a pale ochraceous middorsal 

 stripe from between shoulders to anus; an indistinct darker patch 

 between upper eyelids prolonged to the beginning of the light mid- 

 dorsal stripe; glandular ridges above ear and on back seal brown, 

 the large pre-inguinal glandules clove brown; sides of body olive- 

 buff, with a few small darker spots behind axilla; venter cream buff, 

 immaculate except for some gray suffusions around edge of lower jaw 

 and on the exterior lateral vocal pouches. Side of head chocolate, 

 lighter on edge of rim along upper lip, with a dark oblique spot from 

 anterior eye to lip border, and a few smaller dark spots along upper 

 lip and in front of tympanum; gland at mouth commissure cream 

 buff; anterior and posterior femur dull buff, immaculate; upper limb 

 surfaces pale cinnamon-rufous, with three dark brown crossbands 

 on tibia and traces of these on femur and foot; two similar dark brown 

 bands on forearm; palms and soles cinnamon, with dark spots be- 

 tween joints. 



Remarks. — The tarsus in most of the adult frogs is strongly granular, 

 but in the half-grown ones it is only faintly so. The adpressed heel 

 reaches to the posterior corner of the eye in most examples, and to 

 the center of the eye in a few. The venter is unspotted in most indi- 

 viduals, but occasionally there are some faint darker suffusions on 

 chin and chest. 



In comparing critical measurements of the 30 Colombian specimens 

 at hand, the tibia and foot of the 11 Amazonas frogs were found 

 to average slightly longer proportionately than for the series as a 

 whole, but the difference was not significant.
