1892.] SPECIES OF THE HYRACOIDEA. 69 



bocagei. More specimens, however, to show its variabiHty and 

 geographical distribution will be needed before its true relationship 

 can be cleared up. 



8. Procavia latastei, sp. n. 



Fur close, soft and fine. General colour soft fawn-grey, more 

 pallid than in P. brucei. A large patch on the side of the neck 

 pale yellowish white, the hairs pale at their bases ; this patch is 

 not, however, conspicuous amid the general pallor. 



Dorsal spot narrow, elongate, clear pale yellow to the bases of the 

 hairs ; in fact, just as in P. brucei and bocagei. 



Skull in general form much as in P. brucei, except that it appears 

 to be rather broader and more stoutly made. Muzzle short and 

 conical. Interparietal and coronal sutures persistent. Diastema 

 long, 10 to 12 mm. Teeth small, but proportionally rather larger 

 than in P. brucei. Breadth of m^ 6 to 6'5 mm. pi small, but 

 two-rooted, 3 or 3*1 long. 



Co-types nos. 55-3238 (skin) and 2684 (skull) of the Genoa 

 Museum {coll. LafMste). 



Hab. Senegal. 



M. Lataste obtained several specimens at Fe'lou and Medine, 

 Upper Senegal, and there is a young one in the British Museum 

 received in 1844 from the dealer Parzudaki, and referred to " H. 

 burtoni^' by Gray (Cat. Carn. &c. p. 285). 



From M. Lataste's notes and drawings I gather that he referred 

 his Senegal specimens to P. bocagei, a reference by no means very 

 wrong, as they are unquestionably closely allied to that form. 

 I am, however, induced to separate them, at least for the present, 

 by the fact that the whole of his specimens, 7 in number, besides an 

 eighth, fully adult, of which he gives a drawing, have their inter- 

 parietal sutures persistent, thus differing from P. bocagei, in which 

 the sutures are all closed by about stage IV. or V. 



The close alliance of this species to " Heterohyrax'' brucei in 

 general characters, while it has the open sutures of Pi-ocavia s.s., is 

 a striking proof of the necessity for abolishing Heterohyrax as a 

 separate genus. 



It is with great pleasure that I attach to this species the name of 

 the distinguished author of the paper " Sur le systeme dentaire du 

 genre Daman " \ who collected the specimens himself, and after 

 whom it is particularly suitable that a member of this interesting 

 genus should be named.
