FROGS OF COLOMBIA — COCHRAN AND GOIN 131 



Body moderately elongate, in postaxillary region a little less than the 

 greatest width of head. When hind leg is adpressed, heel reaches 

 posterior corner of eye; in adpressed arm, third finger reaches only to 

 end of sacrum and does not extend behind body; when limbs are 

 laid along the sides, knee and elbow overlap ; when hind legs are bent 

 at right angles to body, heels touch. Skin of upper parts pustular, the 

 pustules mixed with small tubercles on sides, sacrum, and limbs; 

 venter appearing granular because of the crossing of a great number 

 of fine longitudinal and transverse folds; a heavy glandular ridge from 

 posterior corner of eye above tympanum, ending in a short downward 

 bend above the shoulder; a faint skinfold across the chest; no ventral 

 disk; no external vocal sacs in the male, but first finger swollen and 

 curved. 



Dimensions. — Head and body, 25 mm.; head length, 7.5 mm.; 

 head width, 7 mm.; femur, 9 mm.; tibia, 10 mm.; foot, 8.5 mm.; hand, 

 6 mm. 



Color in alcohol. — Dorsum burnt umber with suffusions of russet 

 on the head; an indistinct darker Y-shaped mark from posterior 

 corners of eyelids down the center of the back, apparently forking 

 and continuing diagonally nearly to the sacrum ; venter buff, the belly 

 and lower limb surfaces immaculate, the throat with a large diffuse 

 V-shaped wood brown patch; side of head drab, immaculate but 

 with a russet tinge posteriorly; anterior, superior, and posterior limb 

 surfaces burnt umber with slightly darker tips on the small granules 

 where they occur; palms of hands and soles of feet drab gray, with 

 a suffusion of wood brown at base of two outer toes. 



Remarks. — The female topoparatype (CNHM 69747) has a throat 

 patch of small dark spots that are better defined than in the male, a 

 definite dark X-mark on the head; and the dark-tipped pustules are 

 heavier and more noticeable on the sides of the head and body. 



A male paratype (CNHM 81875, from the C amino Sibate-Aguadita) 

 has larger and heavier tubercles and a more distinct marbling on the 

 back.
