60. Bufo ceratophrys. (Plate XXII. fig. 2.) 



A supraorbital and an orbito-tj-mpanic 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 

 Bubarticular 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 

 cauthus rostralis, and sending off posteriorly a parietal, which first 

 converges towards that opposite, and then runs 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 cauthus rostralis ; a black band 

 from orbit to angle of mouth ; beneath light brown, blackish 

 shaded.
