along the side, knee and elbow overlap slightly; when hind legs are 

 bent at right angles to body, heels overlap considerably. No patagium. 

 Skin of upper parts rather smooth; no discernible parotoid glands. 

 A narrow glandular fold passes downward behind the tympanum; 

 skin of throat, chest, belly, and lower surface of thigh uniformly and 

 very finely granular; no traces of a skinfold across chest; adult female, 

 no vocal sac. Skin of head very thick but not co-ossified with skull, 

 roof of skull not exostosed. 



Dimensions. — Head and body, 35 mm.; head length, 12.2 mm.; 

 head width, 11.8 mm.; femur, 14.4 mm.; tibia, 16.3 mm.; heel-to-toe, 

 23 mm.; hand, 9 mm. 



Color in alcohol. — A dark purplish-blue above, pale yellow below. 

 Upper lip margined with white, this margin broadening below the eye 

 to come in contact with the lower margin of the eye. The light margin 

 of lip continues posteriorly as a light lateral stripe that passes above 

 arm and continues along the side half-way to the groin. Below this 

 lateral light stripe there are faint vermiculations for" about half-way to 

 groin, but posterior to this they become distinct, dark, curlicue-like, 

 markings. The anterior and posterior surfaces of the thighs are pale 

 with distinct, dark, more or less vertical bands, about four on each 

 thigh. The dorsal surfaces of the thighs are faintly pigmented, this 

 dorsal band of pigment separating the dark stripes on the anterior and 

 posterior surfaces of the thighs. The concealed surfaces of shanks, feet, 

 and upper arms are conspicuously marked with dark curlicues. A light 

 stripe on the lateral margin of each hand extends along the ulnar ridge 

 to elbow. A similar stripe on the lateral margin of each foot extends 

 along the lateral margin of each tarsal region to and across the heel, 

 thus giving an impression of a tarsal ridge. A short horizontal white 

 stripe lies just above the vent. 



Remarks.' — It is not at all surprising to find this species in the parts 

 of Colombia east of the Andes. Rivero (1961, p. 51) recorded it from 

 the Venezuelan Guayana. 



We have seen a cotype (TJSNM 5832) from Paraguay and two speci- 

 mens (USNM 48857, 97090) from Pernambuco, Brazil, of what is 

 called P. hypochondrialis azurea Cope from southern South America, 

 and for the time being are willing to go along with Rivero that azurea 

 is a recognizable race of P. hypochondrialis.
