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 m m . Teeth small, but proportionally rather larger than in P. brucei. Breadth of m1 6 to 6'5 m m . P1 small, but two-rooted, 3 or 3-l long. Co-types nos. 55-3238 (skin) and 2684 (skull) of the Genoa Museum (coll. Lataste). 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 interparietal 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 Procavia 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"1, who collected the specimens himself, and after whom it is particularly suitable that a member of this interesting genus should be named. 9.
