Semnopithecus, Fred. Cuv. 



Differs from the Long-tailed Monkeys, by having an additional 

 small tubercle on the last of the inferior molares. They inhabit 

 eastern countries, and their long limbs and very long tail give them 

 a very peculiar appearance. 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 

 larnyx is furnished with a sac. The one longest known is the

 markable for its lively and varied colouring ; body and arms 

 grey ; hands, thighs and feet black ; legs of a lively red j the 

 tail and a large triangular spot upon the loins, white; face 

 orange; he has a black and red collar, and tufts of yellow hairs 

 on the sides of the head ; inhabits Cochin China. (2) 



Another species is remarkable for the very extraordinary form 

 of the nose it is the 



S. nasica, Schr.; Buff. Supp. VII, U and 12. (The Kahau.) 

 Yellow, tinted with red ; nose extremely long and projecting, 

 in the form of a sloping spatula. This monkey inhabits Borneo, 

 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 kahaii. It is also said to be found in Cochin China. 



S. entelluSf Dufres.; Fred. Cuv. pi. 8 and 9. (The Entel- 

 lus.) A light yellowish grey; black hairs on the eye-brows 

 and sides of the head, directed forwards. From Upper Bengal. 

 Is one of the species held in veneration by the Brahmins. 



S. melalophos, Raff.; F. C. pi. 7. (The Simpai.) Fur of 

 a very lively I'ed ; beneath white ; face blue; a crest of black 

 hairs reaching from one ear to the other.

(1) Pennant has described certain Guenons without thumbs, Sim. polycomos and 

 Sim .ferrugi7iea, irom which llliger has constructed his genus Colobus, but I have not 

 yet been able to see them, and for this reason have not mentioned them. M. 

 Temminclc assures us that their head and teeth resemble those of a Semnopithecus. 



(2) M. Diard having transmitted to the Museum several Dotics from Cochin Chi- 

 na, it has been proved that they have callosities on tlie buttocks ; a fact denied 

 by Buffon, on account of his having seen but one specimen injured by stuffing-. 

 The genus Lusiopyga of lUiger must consequently be suppressed, as it is based on 

 this error.
