Dr. J. E. Gray on Sauresia, a new genus of Scincid?e. 281 



the genus Choir opotamus, which is characterized by the males 

 being furnished with a large bony protuberance on each side of 

 the face, about middle distance between the end of the nose and 

 the eyes; both sexes have elongated, rapidly attenuated ears, 

 ending in a pencil of long hairs ; the tail is thick, long and 

 placed high up the back. 



The position of the tail and the lengthened form of the ears at 

 once distinguish these animals from the true Pigs (Sus), which 

 always have a slender tail, and small, hairy, rounded ears. 



The Choiropotami are confined to Africa, while the species of 

 Sus have only hitherto been found in the European and Asiatic 

 quarters of the world. 



The Camaroon Wart Pig, Choir opotamus pictus. Uniform red 

 brown ; the face, forehead, ears, and some large blotches on the 

 legs black ; the edge of the ears, whiskers, streak over and 

 under the eyesj and a continued, rather created streak along the 

 middle of the back, pure white. 



Hab. The Camaroon River, West Africa. A male. 



This is immediately known from the Choiropotamus larvatus 

 of South Africa by the brightness of the colour, the latter being 

 black, whitish washed, white on the side of the face, with a large 

 black spot under the eyes. Sus Koiropotamus of Desmoulin 

 without the protuberances on the face is the female of this 

 species ; the African Hog of DaniePs ' African Scenery,' t. ii., 



ing the adult male.

This genus is described from a specimen brought from St. Do- 

 m.ingo by M. Salle intermixed with other reptiles. Though 

 imported by a French collector and bought from Paris, I do 

 not find any description of it in the second part of the Catalogue 

 of Lizards lately published by M. Dumeril and his nephew 

 M. Auguste Dumeril, which contains the species of this family. 

 It belongs to the well-marked tribe of Diploglossinee, charac- 

 terized by the hard, minutely striated scales ; but it differs from 

 all the genera of that tribe at present known, in having very 

 weak feet with only four rudimentary toes, being in fact the re- 

 presentative of the genus Seps in the other tribes, and forming 

 a good passage between Diploglossus and Ophiodes. 



Sauresia. Body and tail cylindrical elongate; limbs four, 

 short, weak, far apart ; toes 4*4, anterior toes very short, two 

 middle longest, subequal, interior shorter ; hinder very unequal,
