FROGS OF COLOMBIA — COCHRAN AND GOIN 123 



shaped ridges behind the head extending onto anterior part of back; 

 no skinfold across the chest; no ventral disk. External vocal sacs in 

 the male? 



Dimensions. — Head and body, 48 mm.; head length, 13 mm.; head 

 width, 13 mm.; femur, 17 mm.; tibia, 16.5 mm.; foot, 17.5 mm.; 

 hand, 12 mm. 



Color in alcohol. — Dorsum slate-black, with a dorsolateral series of 

 round buff spots covering some of the large tubercles; venter slate- 

 black, with a pair of large irregular buff spots on either side of the chin, 

 with paired buff spots below arm and on side of belly, and with some 

 median buff spots on posterior part of belly; side of head slate-black, 

 a small buff crescent below eye and a light dot below nostril; limbs 

 slate-black with small buff spots behind and below femur, on outside 

 of tibia, and on upper and lower surfaces of tarsus; soles of feet and 

 palms of hands dull drab with a few buff spots, the digits buff below. 



Remarks. — Atelopus ebenoides ebenoides resembles A. bujonijormis 

 chiefly in its truncate snout and its dark color. The feet are entirely 

 different, however, as ebenoides has normally developed toes, while in 

 bujonijormis the fourth toe is relatively very long while the others 

 are extremely short and poorly developed. Also, in ebenoides the 

 tympanum is distinct anteriorly, while in bujonijormis it is hidden 

 under the thick, tuberculated skin. An interesting fact is that one of the 

 two known examples of Colombia bujonijormis also comes from 

 Paramo de las Papas, the type locality of ebenoides. 



An additional example from Tolima, USNM 151325, compares 

 well with the holotype. It is 33 millimeters in length.
