78 ^- S. NATIONAL MUSEUM BULLETIN 206 



dermal characters are very constant in all the specimens at hand, 

 although the degree of development of the heel tubercle (sometimes 

 lacking) and the serrations along the outside of tarsus differ among 

 individuals. A pronounced rudiment of a pollex occurs in the male 

 example of corticalis, as it does in the male examples of pardalis; 

 thus, one of the characters supposedly separating pardalis and corticalis 

 disappears and the latter can properly be considered a synonym of 

 the former (and earlier) name. The presence of a pollex is apparently 

 a characteristic of the male pardalis, as the specimen figured by 

 Burmeister, probably a female, lacks it. The anal ridges are very 

 prominent in the Berlin Museum corticalis and all the examples of 

 pardalis in the U. S. National Museum. 



A very young frog from Marianna, Minas Gerais, MP 704 (part), 

 measuring only 23 mm. in head and body length, is easily recognizable 

 by the same structural features that characterize the adult — the ser- 

 rate glandular fringe on outer forearm and tarsus and particularly 

 the pair of semilunar postanal glands, which stand out beyond the 

 outline of the femur. The eye in so young an individual appears large, 

 almost equalling the distance from its anterior border to the end of 

 the snout; the tympanum is small, less than half the eye diameter, 

 and seems rather distant from the eye ; the vomerine teeth are slender 

 but distinct; and the color pattern is almost faded out, except for a 

 narrow dark line below the canthus, some indistinct dark blotches in 

 the dorsaloteral region, and a few indications of crossbars on forearm, 

 tibia, and foot.
