116 U.S. NATIONAL MUSEUM BULLETIN 2 88 



Remarks. — Since the co types are discolored and in poor condition 

 after more than a century, a fresh example has been chosen for describ- 

 ing and figuring. The maximum known head and body length is 90 

 millimeters, in BM 1914.5.21.88. The toes are from one-fourth to 

 one-third webbed in all examples at hand, and the tarsometatarsal 

 articulation extends far beyond the tip of the snout.

Description. — AMNH 14031, an adult from Andes, Antioquia, 

 Colombia. No bony ridges on top of head. Parotoids large, elongate 

 oval, their length equal to distance from tip of snout to center of eye; 

 tongue two-third as wide as mouth opening, ovate, its posterior 

 border free and unnotched; snout broadly rounded when viewed from 

 above, truncate and sloping backwards in profile, the upper jaw 

 extending well beyond the lower. Nostrils lateral, distinctly projecting, 

 their distance from end of snout about one-third their distance from 

 eye. Can thus rostralis distinct; loreal region flat, vertical, the upper 

 lip flaring out below it. Eye large, prominent, its diameter 1% times 

 its distance from tip of snout; interorbital diameter a trifle greater 

 than that of upper eyelid, equal to interval between nostrils. Tym- 

 panum indistinct. Fingers long, without lateral ridges, free, first 

 finger shorter than second, fourth longer than either, its tip reaching 

 beyond base of penultimate phalanx of third; a small oval thumb pad 

 present; a large round palmar callus; metacarpal tubercles well 

 developed. Toes rather short, one-half webbed, third and fifth toes 

 subequal, their tips reaching to base of antepenultimate phalanx of 

 fourth toe; subarticular tubercles not strongly developed; a very small, 

 oval, inner metatarsal tubercle and a smaller round outer one; an 

 indistinct tarsal ridge, apparently ending at heel; a heavy skinfold on 

 heel and knee. Body moderately stout, in postaxillary region equal to 

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