All the animals of this denomination have a fifth tubercle on their 

 last molares,and callosities and cheek-pouches like a Guenon. The 

 limbs are shorter and thicker than in a Semnopithecus ; the muzzle 

 more projecting, and the superciliary ridge more inflated than in 

 either the one or the other. Though docile when young, they be- 

 come unmanageable when old. They all have a sac which commu- 

 nicates with the larynx under the thyroid cartilage, and which^ when 

 they cry out, becomes filled with air. Their tail is pendent, and 

 takes no part in their motions : they produce early, but are not 

 completely adult for four or five years. The period of gestation is 

 seven months during the rutting season the labia pudendi. Sec. of 

 the females are excessively distended. (3) They are generally brought 

 from India.

(1) There is some variation in their Malay names. Raffles, (Linn. Trans. XIII) 

 calls the S. comata, Chinkau ,- the S. maura, Lotong. Raffles calls the S. fascicu- 

 laris the Ki-a. 



(2) Macaco is the generic appellation of monkeys on the coast of Guinea, and 

 among the negroes transported to the colonies. Marcgrave mentions a species, 

 which he says has " rtares elatas bifidas" and these vague words, copied from him 

 only, have remained in the character applied to the Macaque of Buff, although it 

 has nothing like it. 



(3) Hence the observation of iElian, that monkeys are to be seen in India which 

 have a prolapsus uteri.
