a heavy glandular ridge from posterior corner of eye above tympanum, 

 ending at parotoid, which is small and nearly triangular; a few pointed 

 spicules below tympanum and beneath eye; a fine ridge along rim of 

 upper jaw; no skinfold across the chest; no ventral disk; an external 

 median vocal sac in the male. 



Dimensions. — Head and body, 43 mm. ; head length, 12 mm. ; head 

 width, 14.5 mm.; head height, 6.5 mm.; femur, 14 mm.; tibia, 15.5 

 mm.; foot, 14 mm.; hand, 11 mm. 



Color in alcohol. — Dorsum wood brown with a pair of small oval 

 sepia spots between the shoulders, another crescent-shaped pair at 

 the beginning of the sacrum, and numerous smaller sepia spots sur- 

 rounding the enlarged tubercles along dorsolateral region and nape; 

 upper limb surfaces drab with sepia markings on top of femur, and 

 two large sepia spots on upper surface of tibia and foot; side of head 

 ecru drab, the spicules around eye, nostril, and upper lip dark; side 

 of body drab above fading to dull clay color below with a few in- 

 distinct sepia spots in upper part; venter immaculate clay color; 

 posterior surface of femur drab to clay color with two or three in- 

 distinct darker spots; palms of hands and soles of feet pale clay color, 

 the tips and tubercles darker. 



Remarks. — Some of the minute differences by which Gallardo (1965) 

 distinguishes B. granulosus humboldti from B. g. beebei are partially 

 confirmed by comparing critical measurements of head width and 

 head height. In humboldti the head width is a little greater, while the 

 head height tends to be a little more than in beebei although they 

 slightly overlap. The snout, said to be "elongate" in beebei and 

 "short" in humboldti, is really of about the same proportion in both 

 forms in relation to percentage of head-and-body length.
