This species resembles the Lithodytes habenatus, Cope (supra, p. 109), in the 

 position of the vomerine teeth, but differs much in the form of the feet. In that 

 frog the dilatations are much smaller and the feet much longer. In the hind foot 

 this is chiefly due to the elongation of the fourth toe, which exceeds the third and 

 fifth by three and a sixth phalanges. 



The Lithodytes diastema was found by Dr. Bransford at the camp Mary Caretta, 

 Panama.

Represented by a young male, which displays a number of remarkable charac- 

 ters. The back and median line of the tail support the membranous crest stretched 

 between the elongate neural spines as seen in B. plumifrons, B. mitratus, etc., but 

 the head-crest, instead of being covered, as in those species with large thin scales, 

 presents only small smooth scales like those of the occipital region. This crest is 

 also of smaller size than in the species named, only beginning to rise from a line 

 connecting the tympanic drums, although preceded by a keel to near the line of 

 the border of the orbits. It is not much elevated, but is prolonged chiefly back- 

 wards, and has a truncate posterior outline. Points in which the species differs 

 from the B. cristatus are, the presence of two large scuta bounding the rostral 

 shield above, and the presence of two large labials behind the point of junction 

 with the suborbital ring of scales. There are only ten rays to the dorsal fin, and
