The dentition is similar to that of Semnopithecus maurus, 
Horsfield. With old age the external margin of the ims turns 
gray, and forms what in the human eye is denominated arcus 
senilis. From the peculiar structure of the stomach of the Sem- 
nopithecs, Professor Owen has expressed an opinion, that their 
food consisted of leaves and tender buds of trees, rather than of 
fruits and roots, the food of ordinary monkeys (Zoolog. Transact. 
vol. i.). Dr. Horsfield has recorded that S. maurus during its 
young state feeds on tender leaves, and when adult on wild fruits 
(Zool. Researches in Java). The author of the above-quoted in- 
teresting work upon Monkeys (vol. 1. p. 214) has pointed out the 
peculiarity of the molar teeth of the Semnopithecs being tritu- 
rated at an early period, and justly infers a longitudinal grinding 
motion from front to rear. The present species, as well as S. 
cristatus, exhibits an additional peculiarity about the teeth, which 
at an early age become covered with a dark brown crust similar 
to that observed in ruminating animals. The food of the present 
species consists of leaves, tender buds of different kinds of trees 
as well as of soft fruit ; and the occasional visits of foraging par- 
ties in nutmeg and coffee plantations and gardens is anything but 
welcome to the owners. In its adult state, this, like other Sem- 
nopithecs, is sullen and morose, and is scarcely susceptible of do- 
mestication. Such however is by no means the case during early 
age. A young male, some months in my possession, appeared 
immediately reconciled to his new mode of life, allowed himself 
to be handled, and showed he was not insensible of caresses. But 
being tied up and left in solitude he showed a gentle impatience 
by a most melancholy cry, repeating slowly the syllable “OO,” 
and stretching its arms towards the nearest person, with whom 
he would remain quiet, frequently throwmg its arms round his 
keeper’s neck. When disturbed by a sudden movement, or when 
about being removed from his chosen seat, he would recommence 
his lamentations. In short he expressed a decided aversion to 
solitude and neglect. He frequently used to be in my lap or sit 
on my shoulder while I was reading, and as he was remarkably 
cleanly, these indulgences were readily granted. As already ob- 
served of others of this genus by the author of ‘ Nat. Hist. of 
Monkeys,’ &c., he manifested a great indisposition to action, and.
