M. F. Cuvier divides Phacochcerus into (1) Phacochceres a iuci- 

 sives, P. africanus ; (2) Phacochceres sans incisives, P. cethiopieus, 

 Gmel. (Dent. Mam. 257, 213). He adds, "Notre dessin est tire', 

 pour la machoire superieure d'un Phacochcere saus incisives, et pour 

 la machoire iufe'rieure d'un Phacochcere pourvu d'incisives, et nous 

 ferous remarquer que les disques des dernieres molaires du premier 

 sont moins grands et moins uombreux que ceux de la derniere mo- 

 laire du second, serait-ce encore un caractere specifique?" (Dent. 

 Mamm. p. 213). 



The size and number of the disks on the crown of the last grinder 

 depend on the age of the tooth and how much of the surface has 

 been worn down. 



In the British Museum there are three skeletons and fourteen 

 skulls or parts of skulls. The skulls of ten of these have two inci- 

 sors in the upper jaw, and seven are without any incisors in the 

 upper jaw, as marked in Mr. Gerrard's ' Catalogue of Bones,' p. 280. 

 Two of these skulls belong to skeletons of a male and female Phaco- 

 chere that were brought together from Africa, and lived several 

 years in the Gardens ; they are both destitute of upper cutting-teeth. 

 Another skeleton of a female that lived in the Zoological Gardens 

 has two cutting-teeth in the upper jaw ; so the existence or non- 

 existence of the upper cutting-teeth is not a sexual character. 



The presence or absence of the upper cutting-teeth does not de- 

 pend on the age of the animal ; for there are specimens without any
