MAMMALIA. 
Sim. ferruginea, Pennant ; called by him the “ Bay Monkey.”— Of a deep bay colour above ; cheeks and under- 
parts very bright bay. From Sierra Leone. 
C. Pennantii, Waterh.— Above blackish ; beneath dingy yellow ; the sides yellowish red, and cheeks white. 
From Fernando Po. 
C. TemmincMi, Kuhl. — Blackish above ; I'usty-red beneath and on the cheeks ; the sides yellow. From the 
Gambia. Is identical with C. obscurus, Ogilby. 
The skins of these animals are an article of traffic in Western Africa, but are commonly deprived of the head, 
limbs, and tail. Many Cercopitheci are prepared in the same manner.*] 
The Doucs {Semnopithecus, F. Cuv.) — 
Differ from the true Monkeys by having an additional small tubercle on the last of the inferior molars. 
They are the ordinary Monkeys of the East ; and their lengthened limbs and extremely elongated tail 
[as in Colohus'] give them a peculiar air. Their muzzle projects very little more than that of the 
Gibbons, and, like them, they have callosities on the buttocks ; they appear, likewise, to have no 
cheek-pouches : them larynx is furnished with 
a sac. [The stomach (fig. 3 ) is singularly 
complicated, consisting of three divisions; 
first, a cardiac pouch, with smooth and simple 
parietes, slightly bifid at the extremity; 
secondly, a middle, very wide and sacculated 
portion; thirdly, a narrow, elongated canal, 
sacculated at its commencement, and of simple 
structure towards its termination : their food, 
accordingly, is supposed to be more herba- 
ceous than that of other Catarrhini, which 
is further intimated by the blunter tubercles 
of their molars, and the elongation of then- 
intestines and ccECum. Their hair is of one 
kind only, approaching in character to that of 
Fig. 3. the Gibbons. Their movements are staid and 
deliberate, though capable of much agility ; and the gravity of their deportment is expressed by 
their systematic name. 
Fourteen or fifteen species have been determined, of which the most extraordinary is] 
The Long-nosed or Proboscis Douc {Sim. nasica, Schr. ; Nasalis larvatus, Geof.t) [The S. recurvus, Vig. and 
Horsf., is apparently the young.]— It is of large size, and yellowish colour tinted with red ; the nose extremely 
long and projecting, in form of a sloping spatula. This species inhabits Borneo, and lives in great troops, which 
assemble morning and evening on the branches of the great trees on the banks of the rivers ; its cry is Kahau. 
Is stated also to occur in Cochin China. 
The Variegated Douc {S. nemceus, Geof.)— Remarkable for its lively and varied colouring ; the body and arms 
are grey ; the hands, thighs, and feet black ; legs of a lively red ; the tail, [fore-arm,] and a large triangular spot 
upon the loins, white ; face orange ; and there is also a black and red collar, and tufts of yellow hairs on the sides 
of the head. It inhabits Cochin China. (The genus Lasiopyga of Illiger was founded on a mutilated skin of this 
animal.) 
S. entellns, Dufres. [The species most frequently brought alive to Europe.]— Of a light yellowish grey colour, 
with black hair on the eyebrows and sides of the head, directed forwards. From Upper Bengal, where it is held 
in superstitious reverence. [Some frequent the Pagodas. 
Several are black, dusky, or ash-coloured. S. auratus, Geof., is uniform bright golden yellow, with a black 
patch on each knee. The Simpai {S. melalopJms, Cuv.) is of a very lively red ; beneath white : its face is blue ; 
and a crest of black hairs reaches from one ear to the other. Some have the hair of the head turned up, forming 
a sort of crest. All are from the islands of the Indian Ocean, and neighbouring regions of Asia.] 
The Macaciues (Macacus, Desm.) — 
Possess, like the Doucs, a fifth tubercle on their last molars, and callosities and cheek-pouches like 
the true Monkeys. Their limbs are shorter and stouter than in the former ; their muzzle is more 
elongated, and the superciliary ridge more prominent than in either the one or the other. Though docile 
when young, they become unmanageable with age. They have all a sac which communicates with
