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, Waterb..— Above blackish; beneath dingy yellow; the sides yellowish red, and cheeks white. 

 From Fernando Po. 



C. Temminckii, Kuhl.— Blackish above ; rusty-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 (Setnnopifhecus, 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 Colobus] 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 : their 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 Catarrhlni, which 

 is further intimated by the blunter tubercles 

 of their molars, and the elongation of their 

 intestines and ccecum. Their hair is of one 

 kind only, approaching in character to that of 

 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.f) [The 8. 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. ?iem<eus, Geof.)— Remarkable for its lively and varied colouring : the body and amis 

 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. entellus, 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. melalophus, 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 



Fig. 3.
