IV. — On some new Species of Quadrupeds and Shells. By 



John Edward Gray. 



The British Museum has lately purchased some very interest- 

 ing skins of Quadrupeds from Sierra Leone, among which are 

 the following new species. 



Antilope Zebra, Gray. Back bright fulvous fawn with 

 broad glossy black transverse stripes, beneath pale fulvous ; 

 outer side of legs grey-brown, darker beneath. — This is evi- 

 dently the animal described by my late friend E. T. Bennett 

 in the Proc. Comm. Science Zool. Soc, vol.ii. p. 123, from a very 

 imperfect skin: the one now in the Museum has the tail com- 

 plete, and shows that he was quite correct in thinking that it 

 was probably an antelope, and it is certainly the most brilliant 

 of that beautiful genus. His specimen was said to come from 

 Algoa Bay, but this is probably a mistake, as that in the Mu- 

 seum was sent direct from Sierra Leone. 



Fells neglect a, Gray. Fur very short, brownish grey, with 

 small close blackish spots ; smaller, more elongated, and closer 

 together down the rather darker dorsal line; sides rather paler; 

 throat, belly, and inside of limbs white with larger black spots 

 and stripes; nape darker, with close narrow rather darker 

 lines ; outer side of legs and feet brownish grey not spotted ; 

 tail rather slender, about half the length of the body, grey- 

 brown with a darker central line and varied darker on the sides. 

 Length of body, 3 feet; tail, 15 inches. — Hab. Sierra Leone. 



Unfortunately we have only an imperfect skin, wanting the 

 face and claws, of this highly interesting animal, which must 

 be as large as a small leopard. Among the skins received there 

 is one also of another cat, very like the common domestic cat in 

 appearance, but so regularly and peculiarly marked, as to 

 make me inclined to believe it to be a distinct species, or a 

 very decided variety. 



I will here describe some new Shells from the same country. 



Apporrhais Senegalensis, Gray. Shell regular, spirally stri- 

 ated ; the upper whorls with one central, and the last with 

 two subcentral, series of small nodules, with a series of much 

 smaller tubercles in front of them ; outer lip, with two acute 

 expanded lobes. Axis 13'". — Sierra Leone. My cabinet. 



Fusus elegans, Gray. Shell fusiform, white ; whorls nine,
