1902.] MAMMALS FROM ABYSSINIA. 315 



Fur thick, close, and rather crisp, some of the hairs flattened, 

 though not to be called spiny. Back lineated in the type species. 

 Tail short, closely but finely hairy. 



Skull stoutly built, rather like that of a small short-headed 

 Lopliuromys. Palatal foramina very long ; posterior palate con- 

 tinued some way backward behind molars. Incisors narrow, 

 smooth in front, markedly thrown forwards, so that even the tips 

 of the upper ones do not curve backwards towards the throat. 

 Molars strictly murine, without any marked characteristics. 

 m^ and vi^ each with a large antero-internal accessory cusp, and 

 the former only with a small antero- external one. 



Type. M'us imberbis Riipp. 



Some years ago, by the kindness of the authorities of the 

 Senckenberg Museum, I had the opportunity of examining 

 the type of Ruppell's Mas imberbis, and saw at once that it could 

 not be assigned to any known genus. Now that a specimen has 

 been secured by Mr. Degen I venture to give it a generic name. 



In a general way Muriculus imberbis looks like a pigmy 

 Arvicanthis or Lophuromys, and, while clearly not assignable to 

 any known genus, is somewhat lacking in definitive generic 

 characters, its projecting incisors being its most marked feature. 

 Its whiskers are as abundant as usual, RiippeH's specimen having 

 no doubt lost them accidentally, and it has a distinct dorsal black 

 stripe down the posterior half of the spine. This stripe is not 

 mentioned by RUppell, but is present in the type, as I have 

 personally noted. 



In some ways this is the most interesting of Mr. Degen's 

 captures, and fills an important lacuna in the National Collection 

 of Muridse,

A remarkably dark-coloured Hare, quite unlike any of the pale 

 N. African species. 



Size medium. General colour very dark for an Afi-ican Hare, 

 the general tone of the back approaching Ridgway's '' mummy- 

 brown " ; the underfur with pale slaty greyish bases and buffy 

 tips, the long hairs light for their basal and black for their
