Section B. Etikodontina. Premolars deciduous, their places being 

 filled up by the development of the molars ; molars formed of 

 laminae, many-rooted. 



Family Phacochceridae. 



Phacochcerus. 

 Zygomatic arch very broad, with only a very slight broad 

 concavity in front of the orbit. Lower canines triangular ; the 

 upper canines bent upwards and outwards, very large and 

 thick, with a ridge across their sheath as in the Suidse, but in 

 both sexes. Lower canines flat on the outer sides and keeled 

 in front. The sheath of the upper canines with a very obscure 

 ridge across the middle in skulls said to belong to the two 

 sexes which were living in the Zoological Gardens. The 

 sheath and upper canines of the females are rather smaller and 

 more elongate than those of the males.

 Phacochcerus ^liani and P. africunus, Sclater. 



Dr. Sclater described a young female African pig, with very 

 small canines and small ovate ears with short hair, in the 

 Zoological Gardens, as distinct from P. cethiopicus^ under the 

 name of P. ^liani (Proc. Zool. Soc. 1869, pp. 276, 277, 

 fig. head, & t. xx. animal). In the 'List of Vertebrate 

 Animals in the Zoological Gardens,' 1872, p. 83, the figure 

 of the head is repeated as that of the young of "P. africanus^ 

 Gmelin," with the English name of "Elian's Wart-hog." 

 Gmelin established 8us africanus on the '' Sanglier du Cap 

 Vert" of Buffon (xiv. p. 209, xv. p. 148), and on the "Cape- 

 Verd Hog" in Pennant's 'History of Quadrupeds,' vol. i. 

 p. 146, w^hich was established from Buffbn's description and 

 from a head in the Leverian JVIuseum ; and he adds to 

 Bufibn's description that the ears are "narrow, upright, 

 pointed, and tufted with very long bristles." Bufibn only 

 describes the skull, tail, and hoofs of this animal, but says 

 it has two teeth in the upper jaw, and says nothing about its 

 ears. 



The animal described and figured by Dr. Sclater is still 

 living in the gardens, and no longer has small short canines ; 

 they have become elongate, conical, and bent upwards, like the
