FASCICULI MA LATE USES

* We had three specimens of this species in captivity for some time, all of 
which had been taken from their mothers when too young to fend for them¬ 
selves* Our Malays attempted to teach these monkeys, after they had reached 
a considerable size, to climb trees and bring down fruit, but we were surprised to 
find that not one of them was able to make the initial leap by means of which 
a wild “ kra ” negotiates the bare trunk of a tree below where the branches 
originate. Once they were lifted to the first branch they seemed thoroughly 
at home, but they appeared to have no idea how to commence climbing a tree. 
It is conceivable that this deficiency may have been partly a physical one, due 
to disuse of the hind limb in captivity, but we see no reason to regard this as 
being the case, believing rather that the inability was simply due to lack of 
education on the part of the monkeys, which had never been taught to climb 
by their parents. If this is so, it is a point of great interest in animal psychology. 
It may be well to note in the same connexion that we found that while young 
kittens of Felts bengaknsis were able to swim perfectly well before their eyes 
were open, young Malay otters (.Lutra cinerea ), at the same stage, merely 
floundered about in a quite ineffectual manner when placed in a basin of water, 
and sank almost immediately/

* We had in our possession, for some months, a female of a species allied 
to the preceding, which was said to have been captured on the Patani River. 
Unfortunately, it died and its body was thrown into the river by one of the 
servants. It appeared to us to differ from the common form in having a much 
rounder head and a totally different facial expression, which it is difficult to 
put into words ; in addition, it possessed a small crest, which was formed by 
the hair radiating from a circular whorl on the top of the head, and it was 
evident that when full grown it would have been a much smaller animal. We 
were inclined to regard this specimen as a representative of a species taking 
the place of M. fascicularis in the thickly-wooded central region of the Pen¬ 
insula, very much as Presbytes femoralis probably takes the place of P, oheurus. 
Near Ben dang Stah we saw several large families in the trees on the banks of 
the Patani River, that appeared to belong to the same variety as our captive 
specimen.’
