Type. Native skin without skull. B.M. no. 7.1.2.4. 

 Obtained by R. B. Woosnam. 



This beautiful eastern representative of the West-African 

 Poiana lUchardsoni may be readily recognized by the marked 

 difference in its general body-colour. 



Crossarchus AJexandri, sp. n. 



Allied to C. obscurus, but larger and with much longer 

 skull. 



General appearance very mucli as in C. o^'sciirus, the long 

 loose coat and grizzled colour as in that animal, though the 

 general tone is not so dark. Fur, when the animal is in full 

 pelage, very long, the hairs from 50 to 60 mm. in length; an 

 nnderfur of short woolly hairs present in some specimens. 

 General colour a coarse mixture of black and pale clay-colour, 

 the dorsal hairs pale clay-colour for their basal half (an 

 inconspicuous dark ring present about the middle of their 

 lower half), then broadly black, with a terminal or subterminal 

 band of dull whitish. Wool-hairs pale brown basally, lighter 

 terminally. Under surface similar, but the browner basal 

 part of the pelage more obvious. Crown and middle line of 

 face blacki>h brown, sometimes sharply contrasted with the 

 grey or buffy cheeks and sides of muzzle. Ears pale brown. 

 Lips and chin pale bufFy. Upper surface of forearms, hands, 

 and feet black. Claws very large, the anterior longer than 

 the posterior. Tail long-haired at base, evenly tapering, 

 mixed black and greyish like the body. 



In some specimens, taken probably at a different season, 

 the long loose hairs are few or absent, and the whole body is 

 clothed in a short coat of greyish untlertur. 



Skull conspicuously different from that of C. ohscurus by 

 its very much greater length, the breadth being about the 

 same. Teeth much longer throughout.

Head and body 4.50 mm. ; tail (c.) 290 ; liind foot (s. u.) 77 ; 

 longest front claw (above) 14*5: longest liind claw 9.
