A very typical series showing no variation. The immature specimen is 
just losing the first yellow pelage which is only left on the hind-quarters and 
tail. Over the rest of the body the hairs are of a uniform greyish-black, the 
light patch on the occiput being hardly distinguishable. 
* Thelotong is very generally distributed over those parts of the Peninsula 
that we visited, with the exception of South Perak. Near Biscrat it was very 
abundant on the craggy limestone hills in the vicinity, where it was practically 
inaccessible, but it never approached the village. Among the casuarinas on 
Tanjong Patani it was abundant and tame, keeping in troops of one old male with 
five or six females and young ; these old males are said by the natives to be 
frequently very savage and even to attack small children. In habits it is much 
more arboreal than the “ kra,” and we never saw one of them on the ground. 
Judging from two specimens obtained the young must be born about February 
or March (at the end of the stormy season), and until they are about one- 
third grown are of a beautiful golden-yellow colour, with fur of a soft and 
silky texture. 
1 When driven on to an isolated tree these monkeys would ascend the trunk 
as high as they could, and then strive to conceal themselves by pressing their 
bodies as closely as possible against the trunk or some large branch, under 
which circumstances it was very difficult to make them out exactly. At Tan- 
jong Patani the food of those specimens which we examined had consisted 
entirely of the young shoots of the casuarina. 
1 A curious change has taken place in the habits of this species at Biserat 
within the last two years. When Annandale was there in 1899 as a member 
of the c Skeat * Expedition, it was common among the fruit trees of the village, 
into which one or more families came down from the hills nearly every day. 
The natives deny that it ever does so now. The reason for the change is 
probably that the houses of Biserat have recently been separated from one 
another by a broad roadway. Possibly also the large numbers of Siamese and 
Chinamen now settled there may have something to do with the disappearance 
of the lotong from the village, for these two races, unlike the Malays, eat the 
flesh of the monkey, believing that it has strong tonic qualities, especially for 
pregnant women. We noticed that while P. obsamts was extremely wary in 
the interior, it was comparatively tame in the neighbourhood of the purely 
Malay fishing villages on the coast.'
