recurved prepollex with an exposed spine directed inward. Skin 

 finely glandular above, almost smooth; skin of abdomen and ventral 

 surfaces of the thighs coarsely granular; a supra-tympanic fold but 

 no dorso-lateral one; a subgular vocal sac present. 



"Ground tone (of preserved specimen) pale grayish blue above, 

 suffused with a darker tone; some indication of nine transverse bars 

 of a dark brown on the back; a more distinct series of five or six bars 

 on the thighs; upper surface sprinkled with about thirty small white 

 spots; ventral surfaces straw-color to yellowish; axilla a bright orange; 

 groin and inner side of arms and part of the gular region a bluish 

 tone; posterior surfaces of thighs of the same pale tone as the ventral 

 surfaces. 



"Measurements. — Tip of snout to vent, 48.0 mm.; tip of snout to 

 posterior border of tympanum, 17.0 mm.; greatest breadth of head, 

 18.5 mm.; distance from axilla to tip of longest finger, 31.0 mm.; 

 distance from vent to tip of longest toe, 81.0 mm.; tibia, 26.0 nun." 



Remarks. — The paratype, A.M.N.H. No. 31307, differs from the 

 description of the type in the following minor details: The can thus 

 rostralis appears fairly distinct, as the loreal region is quite concave; 

 no sharp spine projects from the poUex; tibiotarsal articulation 

 extends only as far as anterior corner of eye. In addition, the supra- 

 tympanic fold is continued as a crescentic skin fold above the arm 

 insertion, and as a straight fold along the side of the body nearly to 

 the groin. No dorsal cross bars or scattered white spots are to be 

 seen on this paratype, while the bright orange and bluish tones have 

 faded, leaving the entire frog a dull buff. Its dimensions are: Head 

 and body, 38 nun.; head length, 17 mm.; head width, 18 mm.; eye 

 diameter, 5 mm.; foreleg, 16 mm.; hindleg, 80 mm.; tibia, 25 mm.; 

 femur, 26 mm. from anus, 23 mm. from groin. 



The only other example of this species examined by me is M.C.Z. 

 No. 23539, taken in 1938 at Los Limones, Dominican Republic, by 

 P. J. Darlington.
