5. Description of a new Species of Chrysochloris from South 
Africa. By Dr. Atsrert Gintuer, V.P.Z.S. 
[Received April 3, 1875.] 
(Plate XLIII.) 
Mr. Herbert Trevelyan has presented to the Trustees of the British 
Museum the skin of a new species of Chrysochloris, which is distin- 
guished by its gigantic size, being nearly-double the size of any of the 
other species known. He obtained it from a Kaffir who accompanied 
a shooting-party in the Pirie Forest near King William’s town (British 
Caffraria), and believes that it must be very scarce or local, as none_ 
of his companions had ever seen another specimen. Unfortunately 
the skull has not been preserved; otherwise the skin is in a most 
perfect condition. I name this species after its discoverer, and cha- 
racterize it as follows :— 
CHRYSOCHLORIS TREVELYANI. 
Nine and a half inches long. The colour and quality of the fur 
reminds one of that of an Otter; it is moderately long, rather stiff, 
and of a deep chocolate-brown colour, with a dense whitish under- 
fur. Margin of the lips white. On the abdomen the fur is less dense 
and shorter ; and patches of the whitish under-fur are visible in the 
posterior parts of the abdomen. Muffle flat, projecting as in the other 
species, but comparatively narrower. Claws whitish; the inner and
