BATRACHIA SALIENTIA. 69 



tubercles, and nothing of a fold is to be seen. The toes are half- 

 webbed ; the third rather longer than the fifth. There are two small 

 and blunt tubercles on the metatarsus. The system of the coloration 

 of the upper parts is very similar to that of Bufo ornatus. Ground 

 colour greyish brown or brown ; a more or less distinct, uninterrupted 

 yellowish line from the muzzle to the end of the coccygeal style ; on 

 both sides of it symmetrical reddish-brown markings, the most con- 

 stant of which are a broad cross-band betAveen the eyes, and two 

 irregular blotches on the sacral region ; arms and legs with a few 

 cross-bands. The coloration of the lower parts appears to be a 

 constant character : the tlu-oat, breast and upper part of belly are 

 thickly covered vsdth dark brown more or less confluent spots ; these 

 parts become lighter with age, but across the middle appears a white 

 rectangular cross, the horizontal branches of which reach from one 

 humeral joint to the other. Length of body 2" ; length of anterior 

 extremity l^-" ; length of posterior extremity 2i". 



3. OTILOPHUS. 



Head moderate, angular ; muzzle distinct and pointed ; crown on 

 each side with an enormous, erect, shaip, bony ridge from the orbit

 fold. Teeth none in jaws nor in palate ; eustachian tubes moderate. 

 Tongue oval, entire, free behind. Tympanum more or less distinct ; 

 paratoids prominent ; skin warty. Fingers four, free ; toes five, 

 half- webbed. Male with a single internal vocal sac. South America.
