A very conspicuous projection on the lower edge of the mandible marks the boundary between the incisive and molar portions of the bone. e Fig. 2a• f Skull of Tricl~ys lipu1'a, natural size. The animal described is undoubtedly the same as that of which a fragmentary skull has been figured by M. Gervais, Voy. Bonite, Mamm. pI. 11. figs. 4-6. The author thought it to be identical with Hystrix maCl'w'a (Gm.). As far as I can make out from his description, his materials were :- 1. A dried example, said to have been brought by the naturalists of ' La Bonite' from Sumatra., where it is called" Landa Kloele." This specimen is also tailless; but M. Gervais adds that he had convinced himself, "qu'il avait He mutile, lors de la preparation." No mutilation of any kind has taken place in our Bornean specimen brought by Mr. Low, who, besides, assures me that the natives had told him that this species was tailless. 2. The fragmentary skull taken from that skin, figured by M. Gervais, about the identity of which with that of our animal there cannot be any doubt. 3. But, singularly, M. Gervais refers further to this species the skeleton of a long-tailed Porcupine with twenty-one caudal vertebrret, * According to Eydoux's Itinerary, the expedition did not touch at Sumatra. (V oy. Bonite, Zoo!. i. p. xiii.). . . ,,' t The numbers of vertebrre are ddfer ently glven on p. 63; but Acanthwn macrourum" is probably a slip of the pen. PROC. ZOOL. Soc.-1876, No. XLIX. 49 |
