FASCICULI MALA TENSES 
This series shows a considerable amount of variation, the male from 
Nawngehik belonging to the rufous coloured variety (Af. aureus), which colour 
is also approached by two specimens from Biserat ; the remainder are of various 
shades, all belonging to the commoner greenish-brown type. 
The skull of one of the females from Biserat shows certain conspicuous 
differences in the teeth, also in the general build of the skull and size of the 
bullae. It may possibly be specifically distinct, but much more evidence bear¬ 
ing on the point is required before a definite opinion can be pronounced. 
For many years this species has been known under the name of 
M. cynomolgus (Linn.), a name which should, unfortunately, no longer be used 
for it, as it undoubtedly belongs to an African species, probably a baboon. 
Nor is the name M. cynomolgus (Buffon nee Linn.), as used by Blanford, 
available, as this species, renamed M. irus by Cuvibr, was founded on what 
Buffon considered to be M. angolensis major , Rev, but which Cuvier shows 
to be a different species from Senegal, intermediate between the Guenons and 
Baboons. There is, therefore, no choice but to fall back on Raffles’ species, 
which is well described, leaving little doubt as to the animal intended. 
‘The U kra,” “krah," or “kerah," as it is variously called in different parts 
of the Peninsula, was common in all districts on the East Coast visited by us. 
It was specially numerous among the mangroves of the tidal creeks near Jambu, 
and was also not uncommon at Biserat, where specimens were obtained as they 
came to feed on the young Indian corn in a newly-made jungle clearing. In 
South Perak, where monkeys of all species are scarce, possibly owing to the 
presence of a large aboriginal population, we did not meet with it, but it was 
abundant in the vicinity of Kuala Lumpur, Selangor. 
Contrary to the experience of many naturalists we found the "kra” very 
wary, more especially upon the sea coast, where it was found impossible to 
obtain specimens without the expenditure of a quite disproportionate amount 
of time. It is frequently to be seen upon the ground walking with a peculiar 
stride and holding the tail parallel to the general line of the body. When the 
tide is low it often frequents the mud banks in search of crustaceans, etc., 
retreating to the mangroves when disturbed and chattering defiance at the 
intruder at a safe distance. The alarm-note is a rattle-like cry, from which the 
vernacular name is possibly derived. When young they are very commonly 
captured for pets by the natives, and one or two may generally be seen beneath 
the houses in almost every village, but it is very rare to see a really adult male 
in captivity, as they become very vicious on approaching maturity. Younger 
specimens seem, as a rule, much more ferruginous in colour than the older 
ones.
