REPORT ON ZOOLOGY, MDCCCXLII ; 
In the Ann. of Nat. Hist. ix. p. 503, Owen has shown that the 
stomach, caecum, and the rest of the intestinal canal, in the Colobus 
urmius, are of the same nature as in the Semnopithecus, which was to 
be expected after Riippell had proved the same thing in the Cololms 
guereza ; cheek pouches wanting. Owen has confirmed the identity of 
the C. ursinus with polycomos, as shown by myself. The latter name is 
to be retained as the original. 
Mr. Thomson, Surgeon of the last Niger Expedition, brought home a 
large arm-shield, made from the skin of Colohus guereza. The shield 
consists of the greater part of the back with the white stripe ; and is 
distinguished from an Abyssinian specimen in the British Museum, by 
the white band being considerably broader, and not furnished with quite 
such long hair. (Ann. Nat. Hist. x. p. 203). 
For fixing the hitherto very uncertain accounts of the habitat of a 
great portion of the African Apes, the following notices of Fraser, the 
Naturalist of the last Niger Expedition, are worthy of attention. (Ann. 
of Nat. Hist. ix. p. 262). In the neighbourhood of Sierra Leone, were 
found Simla troglodytes, Colobus ursinus, Gercopithecus fuliginosus 
(common), C. Sabceus, and Cynocephalus papio. At Bassa, Fraser saw 
some skins of Gercopithecus Diana, said to be common there. At Cape 
Coast, Gercopithecus petaurista is to be found, and Colobus leucomeros ; 
skins of the latter, as well as of Gercopithecus Diana, were extremely 
plentiful at Accra. 
Is. Geofifroy lias, in D’Orbign. Diet. Univ. d’Hist. Nat. iii. 
р. 296, furnished a Monograph on the Genus Gercopithecus. 
After the separation of the Mangabeys {Gercopithecus fuliginosus and 
cethiops, as well as C. talapoin), the author enumerates stHl twenty species 
of Gercopithecus, in which aU the grinders are four-sided, and have four 
tubercles. He groups them in the following way : — A. Snout somewhat 
shorter, body slender, disposition peaceful and soft : a. Nose hairy and 
white. — 1. C. nictitans: 2. C. petau/rista ; my description of an old 
male is not noticed, although the difference is considerable, b. Sides and 
imder part of the face covered with very long hairs : 3. C. pogonias. 
с. Tail lively red ; 4. G. cephus : 5. C. erythrotis. d. Tail of different 
colours, but dull ; above the eyes no white bands : 6. G. labiatus, a new 
species of Is. Geoffroy which, by the colour of the upper side and dispo- 
sition of the cheek hair, is very similar to the G. nictitans, but is different 
in the colour of the under side and tail ; the former is dirty white ; the 
latter is, in a great extent, dirty fulvous beneath, and red and black 
speckled above; the rest black: habitat unknown: 7. G. Campbelli: 
8. C. Martini : 9. C. Temminchii ; doubtful : 10. C. monoides, a new 
species of Is. Geoffroy, like the Mona, but of a different colour on the 
under part of the body, which, in the C. monoides, is greyish : habitat
