Color in alcohol. — Dorsum seal brown to walnut brown, lightening 

 on sides to wood brown; venter wood brown, immaculate except for 

 some darker shadings between the granules on posterior belly; side 

 of head immaculate fawn color, becoming a little darker near can thus; 

 anterior femur seal brown on upper half, light wood brown on lower 

 half; posterior thigh Mars brown with one or two paler spots; soles 

 of feet and palms of hands pale wood brown, their tubercles and 

 webs similar in color. 



Remarks. — 'The relationships of Niceforonia nana are at present 

 not clear. In many ways this species is structurally more like the forms 

 of Borborocoetes which lack the tympanum. 



When first examined, the type gives one the impression that it is 

 an immature frog, but it is a female packed with large ripe eggs. 



The large unpigmented eggs (approximately two millimeters in 

 diameter) probably indicate that Niceforonia nana is a terrestrial 

 breeder. This would not be unexpected or inappropriate for a frog 

 inhabiting the paramos.

 weakly developed. Sternal style bifurcate. Tympanum not distinct, 

 its posterior border usually not readily visible. Skin of dorsum fairly 

 smooth, seldom possessing the short raised glandular lines outlining 

 the pattern, as in typical P. neglectus (Ahl). Sole of foot smooth, or 

 nearly so.
