axillary region distinctly narrower than greatest width of head; 

 when hind leg is adpressed, heel reaches beyond tip of snout; when 

 limbs are laid along the side, knee and elbow overlap appreciably; 

 when hind legs are bent at right angles to body, heels overlap some- 

 what. No patagium. Skin of upper parts finely granular, a moderately 

 heavy glandular fold (parotoid) hangs behind the tympanum and angle 

 of jaw to about the level of the lower margin of jaw, a distinct (glandu- 

 lar?) flap extends out above the vent. Skin of throat and chest smooth, 

 that of belly and lower femur uniformly granular; no apparent traces 

 of a skinfold across the chest; no inguinal gland; no apparent vocal 

 sac. Skin of head not co-ossified with skull, roof of skull not exostosed. 



Dimensions. — Head and body, 62.7 mm.; head length, 19.2 mm.; 

 head width, 21.3 mm.; femur, 31.9 mm.; tibia (exclusive of dermal 

 flap), 33.7 mm.; foot, 42 mm.; hand 21.4 mm. 



Color in alcohol. — A nearly uniform dorsal dark color, very sharply 

 separated from the uniform (with exceptions noted below) ventral 

 light color; a series of black, narrow, finger-like projections extending 

 downward from the dark dorsal color into the ventral light color. The 

 dorsal dark color is now a deep blue and completely covers the top 

 of the head and back. There are margins of this dorsal color along 

 the margin of the lower jaw, along the upper surface of the forearm 

 and the lateral dorsal surface of the fourth finger; a narrow stripe of 

 this dorsal color extends from the hip along the dorsal margin of the 

 thigh to the knees. The dorsal surface of the shank bears the dorsal 

 ground color, as does the dorsal surface of the metatarsal region and the 

 dorsal surface of the fifth toe. There is a pencil stripe along the distal 

 dorsal portion of the upper arm. A series of about half a dozen black, 

 finger-like processes extend down from the dorsal ground color be- 

 tween the head and groin; a similar number extend down both an- 

 teriorly and posteriorly from the stripe of dorsal color on the thigh, 

 on the inner (but not outer) margin of the shank, and several are 

 present on top of the foot, with a similar splash on the middle of each 

 fifth toe. The pale ventral ground color is interrupted only by some 

 brown markings on the ventral surface of the wrist and fourth finger 

 and by some brown spots slightly below and on each side of the vent, 

 on the ventral surface of the metatarsal region, the base of the fourth 

 toe, and the entire fifth toe. 



Variation. — The variation in the adult specimens is nearly im- 

 perceptible. In the two adults at hand, BM 1902.5.27.26 [1947.2.24.22], 

 the type, and BM 1913.11.12.126), the only perceptible difference 

 is that the type has a little more pronounced fold over the vent and a 

 little shorter snout. Color-wise, the two are exactly alike except that 

 the type lacks the pencil-like stripe along the distal, dorsal surface of 

 the upper arm.
