disheveled. Thus he rolls heavily along to reach the nearest tree. 

 Should the distance be found too long, he frequently rests. 



In the jungle I have never observed this monkey on the ground, 

 but troops from five or six to some twenty watch with curiosity 

 from on high the intruder, and when frightened they will perform 

 astounding leaps, while they express their fear or annoyance by 

 a hoarse short cry. If one is shot, the others fly to a short di- 

 stance, stop and observe the wounded, but attempt not to carry 

 him off. Judging by the physiognomy and the proportions of 

 the limbs, this species appears to be nearest allied to S. mauras, 

 Horsfield. The white lips occur in S. Nestor, Bennet, but the 

 white eyelids have hitherto been considered to be a character 

 almost confined to certain African Cercopithecs (Nat. Hist, of 

 Monkeys, &c., vol. i. p. 318). But Semnopithecus cristatus of 

 the Malayan Peninsula and Prince of Wales Island has the eye- 

 lids of a much lighter, almost whitish, colour than the rest of 

 the face, and in Cercopithecus {Macacus) cynomolgus (Simia ay- 

 gula) of the same localities the upper eyelids are whitish. 



The white marks however become obliterated shortly after 

 death, and are scarcely discernible in preserved specimens. S, 

 halonifer is denominated by the Malays of Prince of Wales Island 

 by the general appellation of " Lutung " (a monkey), or " Lutung 

 itam" (black monkey), both of which names however are also in- 

 discriminately applied to S, cristatus and S. maurus.

The stomach consists of three distinctly separated divisions, as 

 described by Prof. Owen in S. entellus, but presents in this spe- 

 cies a much less sacculated appearance, and differs more parti- 

 cularly in the second or middle compartment having smooth and 

 not sacculated parietes, and being of a crescent shape. The py- 

 loric portion is a cylindrical canal, gradually diminishing in dia- 

 meter towards the pylorus ; first of a sigmoid figure, then turn- 

 ing upon itself. It is in a less degree puckered up upon the two 

 bands than is the case in the Entellus, and the sacculi cease about 

 3^ inches from the pylorus. When distended the stomach mea-
