27 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. Felts neglecta, 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,
