 well developed, rising above the level of the condyle. A very con- 

 spicuous projection on the lower edge of the mandible marks the 

 boundary between the incisive and molar portions of the bone.

Skull of Trichys lipura, 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 macrura (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 " Lancia Kloele." 

 This specimen is also tailless; but INI. Gervais adds that he had con- 

 vinced himself, "qu'il avait etc 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 vertebroef, 



* According to Eydoux's Itinerary, the expedition did not touch at Sumatra 

 (Voy. Bonite, Zool. i. p. xiii.). 



t The numbers of vertebra? are differently given on p. G3 ; but " Acanthion 

 macrovrum " is probably a slip of the pen.
