60. Bufo ceratophrys. (Pxrare XXII. fig. 2.) 
A supraorbital and an orbito-tympanic bony ridge; an indica- 
tion of a parietal ridge; snout short, truncate, with angular canthus 
rostralis; upper eyelid produced in a horn-like appendage, the 
length of which is greater than the orbital diameter; tympanum 
distinct, rather more than half the width of the eye. First finger 
extending beyond second; toes webbed at the base only, with simple 
subarticular tubercles; two small metatarsal tubercles; no tarsal 
fold. The hind limb being carried forwards along the body, the 
tarso-metatarsal articulation reaches the tip of the snout. Skin 
covered with very small tubercles; parotoids moderate, subovate ; 
a series of four pointed appendages on each side of the body. 
Greyish brown above, with dark-brown markings; sides dark- 
brown marbled ; lower surfaces slightly spotted with brownish.

61. Bufo dialophus. - 
Chilophryne dialopha, Cope, Proc. Ac. Philad. 1862, p. 341. 
Pre- and postorbital, supra-tympanic, and supraorbital ridges 
well developed, the last marking a very open angle with that of the 
canthus rostralis, and sending off posteriorly a parietal, which first 
converges towards. that opposite, and then rans transversely on the 
occiput to meet it, failing in this by a very slight interval. Snout 
prominent, conic. Tympanum one fourth the size of the orbit. 
First finger shorter than second, which equals the third ; toes short, 
one-third webbed ; two acute metatarsal tubercles, the internal large, 
incurved, like a flattened spur. Skin everywhere rigidly rugose ; 
parotoids large, short, subtriangular. Above dark brown, with a 
pale vertebral band, on either side of which are two blackish dorsal 
spots, one temporal and one on the canthus rostralis ; a black band 
from orbit to angle of mouth; beneath light brown, blackish 
shaded. /
