The skeleton presents twelve dorsal-vertebrae with twehe 

 pair of ribs, seven lumbares and twelve sacrales and caudales: in 

 the skeleton of the other Hare-species there are the same 

 number of vertebrae dorsales and lumbares and of ribs , 

 but the sacral and caudal vertebrae are always more nu- 

 merous , viz: from nineteen to twenty-four. With regard to the 

 number of vertebrae in the short tail the Sumatran spe- 

 cies agrees with the genus Lagomys , but in Lagomys there 

 are always seventeen pair of ribs and four or five lumbares. 



The skull of our new species compared with that of the 

 other Hares presents the following particularities; the antorbi- 

 tal foramina as usually present an open bony network but the 

 zygomatic arches are less strong than in other Hares; the 

 nasal bones are broader and less elongated than in true 

 Hares and agree more with these parts in L. hispidus; 

 the same is the case with the bony palate , which is nearly 

 as long as broad, and with the incisors which are very 

 strong and broad ; the distance between the molar series 

 and also between the zygomatic arches is very great. In 

 structure and proportions of the skull the Sumatran Hare 

 agrees more with L. hispidus than with any other known 

 Xe/>Ms-species.
