3. DescRIPTION OF TWO SPECIES OF MAMMALIA FROM CARACCAS. 
By J=E. Gray, Esa.,-F.R.S. ere. ° 
The British Museum have lately purchased from M. Sallé, through 
Mr. Cuming, a Monkey and a Squirrel, which appear to have been 
hitherto unnoticed in the catalogues; I have therefore sent a short 
description of them to the Society. 
Myceres paLuiatus (Mantled Howler). 
(Mammalia, pl. 6.) 
Black brown ; hair of the middle of the back and upper part of the 
sides yellow brown, with black tips ; of the lower part of the sides 
elongate brownish yellow, forming a kind of mantle on each side. 
Hab. Caraccas. 
The hair of the forehead short, reflexed, forming a slight crest 
across the middle of the head ; of the back of the head rather longer ; 
of the cheeks few, scattered, short and greyish; of the hinder part 
of these rather longer than those on the rest of the head, and form- 
ing a slight beard, which is more distinct in the males; the lower 
part of the hairs on the shoulders is sometimes yellowish. 
Scrurvs porsauis (Black-backed Squirrel). 
(Mammaiia, pl. 7.) 
White, hairs black, witlf, more or less, long white tips; the eye- 
brows, back of the head, nape and middle of the back brownish black, 
forming a very broad, well-defined dorsal streak. 
Hab. Caraccas. ; 
The black of the hairs of the sides of the body and tail show through 
the general white colour ; the black occupies all except the tip of the 
hairs. The hairs of the lower part of the legs and feet are white to 
the base; ears rounded, not bearded, and with scattered hairs. 
This may be only a variety of some other American species, but 
the two specimens which were sent home were exactly alike. 
4. DescrIPTION OF A NEW SPECIES OF HERPESTES, FROM ABYSSINIA. 
By J. E. Gray, Esa., F.R.S. erc. 
Mr. F. H. Hora having kindly presented to the Museum a specimen 
of a male Herpestes which he lately caught in Abyssinia, and as it 
is different from any of the species of the genus described by Dr. Rup- 
pell in his Fauna of that country, original specimens of which are in 
the British Museum collection, I have the pleasure of laying a short 
description of it before the Society for publication in the Proceedings. 
HERPEsTES ocHRACEvs (Ochraceous Herpestes). 
(Mammalia, pl. 8.) 
Pale brownish yellow, very minutely mixed or punctated with a
