behind the choanae and separated from each other by a wide space; 

 tongue elliptical, unemarginate behind. Skin smooth above and 

 below; a glandular dorso-lateral fold extending from the eye to lumbar 

 region. 



"Ground tone above flesh-color to pale gray, ventral surfaces 

 slightly paler; a stripe of dark brown extending from the nostrils 

 along the canthus rostralis to eye, broadening out behind the eye to 

 form a conspicuous supra-tympanic crescent, another stripe of dark 

 brown extending along the dorso-lateral fold to anus, the stripe inter- 

 rupted at a number of points; sides of the body immediately below 

 the dorso-lateral fold mottled or spotted with dark brown; the lower 

 half of the sides feebly stippled with brown, posterior surfaces of the 

 thighs dark brown, a narrow white line running obliquely across each 

 thigh and meeting its mate of the opposite side above the anus; 

 posterior surfaces of the tibia washed with dark brown; two or three 

 feebly indicated bars across the dorsal surfaces of the tibia. 



"Measurements. — Tip of snout to vent, 17.5 mm.; tip of snout to 

 posterior border of tympanum, 6.5 mm.; greatest breadth of head, 

 6.2 mm. ; distance from axilla to tip of longest finger, 9.5 mm. ; distance 

 from vent to tip of longest toe, 25.0 mm.; tibia, 8.2 mm." 



Remarks. — The paratype, A.M.N.H. No. 31406, approaches the 

 description of the type very closely except in the following details: 

 The tympanum of the former is about half its own diameter from the 

 eye, while the dorsal skin is finely shagreened and that of the venter 

 is slightly granular. The paratype has the following dimensions: 

 Head and body, 18 mm.; head length, 6 mm.; head width, 6 mm.; 

 foreleg, 11 mm.; hindleg from vent, 24 mm.; tibia, 8 mm. The frogs 

 from Loma Vieja agree well with the paratype of minutus, except 

 that the heel reaches the posterior corner of the eye in most cases. 

 The back of U.S.N.M. No. 107576, a female, is quite smooth, as 

 that of the type is said to be, while that of the male, U.S.N.M. No. 

 107575, is very faintly shagreened. The snout of the male is also a 

 trifle shorter than those of the female and paratype. Their hindlegs 

 measure 146 and 141 percent of the total length, respectively, and the 

 tibia 44 percent of the total length in both, in which respects they are 

 very close to the type and paratype. Further collecting should bring 

 out interesting facts regarding the exact distribution of this species 

 and its close relative intermedins from the same mountain range. 



Specimens examined. — A.M.N.H. No. 31406, paratype, presumably 

 a male, Paso Bajito, Dominican Republic, September 4, 1922, G. K. 

 Noble; M.C.Z. Nos. 23515-23519, from Loma Vieja, Cordillera 

 Central south of Constanza, Dominican Republic, August 1938, 

 P. J. Darlington; U.S.N.M. Nos. 107575-107576, from Loma Vieja, 

 same data.
