FROGS OP COLOMBIA — COCHRAN AND GOIN 493 



throat, and lower thigh; a fine glandular ridge from posterior corner 

 of eye above tympanum, ending behind it; no skinfold across chest; 

 no ventral disk. 



Dimensions. — Head and body, 22 mm.; head length, 8 mm.; head 

 width, 8.5 mm.; femur, 8 mm.; tibia, 8.5 mm.; foot, 8 mm.; hand, 

 6 mm. 



Color in alcohol. — Dorsum clove brown, the glandular lines olive- 

 gray; a pair of large russet spots on upper surface of tibia between 

 the diagonal glandular ridges; throat, chest, and most of belly clove 

 brown, except for a narrow buff rim around lower jaw and several 

 large buff spots across posterior abdomen; lower limb surfaces buff 

 with numerous brown marblings, especially on lower thigh and arm, 

 and a brown patch on heel and elbow; side of head with a large buff 

 spot from edge of upper lip to eye; can thus, loreal region and posterior 

 part of jaw dull clove brown; side of body uniform clove brown except 

 for a very large buff to rose pink inguinal patch and a small axillary 

 spot, both with irregular outlines; anterior and posterior thigh rose 

 pink with a few brown marblings, the brown concentrated below anus 

 in an irregular, dark postanal patch; palms of hands and soles of feet 

 buff, the latter with some brown marblings on three outer toes. 



Remarks. — Since this individual is a mature female containing 

 large, unpigmented eggs, it is probable that the species is a terrestrial 

 breeder. The abdominal eggs are, like those of Niceforonia, two 

 millimeters in diameter. 



The holotype (CAS 85177, from Narino) was the only specimen 

 examined. 



Subfamily Rhinodermatinae 



Sternum and omosternum cartilaginous. Epicoracoid cartilages 

 partly fused. Sacral diapophyses dilated. Vertebrae tend to fuse, 

 especially the sacral vertebra with the urostyle. 



Genus Geobatrachus Ruthven 



1915. Geobatrachus Ruthven, p. 1 (type species, Geobatrachus walkeri Ruthven). 



Generic diagnosis. — Rounded sacral diapophyses, concealed tym- 

 panum, fingers and toes free of web, no vomerine teeth, an omoster- 

 num present, toes four. Only one species is now known in the genus. 

 It may be distinguished from bufonids and atelopids by the presence 

 of an omosternum; from the other Colombian leptodactylids by the 

 combination of rounded sacral diapophyses, concealed tympanum, 

 and lack of vomerine teeth, and from all of them by having only four 

 toes on the hind foot.
