MAMMALS COLLECTED IN SIAM. 351 
One male (2285) is rather more warmly coloured than the 
rest of the series, the yellow in the upper pelage being ochraceous- 
buff and the speckling of the fore-limbs correspondingly brighter, 
but otherwise it agrees. 
I did not obtain any monkeys on the coast adjacent to Koh 
Kram so it is impossible to say yet whether this is an insular race 
or has a greater range: animals from Korat and Chantabun do not 
resemble it. It is a striking looking macaque on account of its black 
cap and bright skin colours, the face being such a red-brown that 
the collector who first saw it reported that M.rufescens, with 
which he was acquainted, was in the neighbourhood. The skin 
colours of the females differ slightly from those of the males, in that 
the teats are bluish-pink, the skin surrounding both anus and cal- 
losities is plum-coloured an1 the callosities are dull pale yellow and 
bluish mixed. 
The slight up-standing occipital crest is sometimes rather 
irregular and twisted; it is generally produced by the radiation of 
the hair from two closely adjacent points.

A very dull-coloured specimen; general colour above dull, 
slightly greyish buff, rather brighter on limbs and sides, the head, 
neck and median line of back tinged with ochraceous-tawny. The 
hlack spots on the sides are generally situated at the posterior end 
of indistinct ochraceous-tawny patches which sometimes connect 
two or three spots together; spots on the limbs rounder and very 
small at the extremities; two large elongate ochraceous-tawny 
areas on the shoulders nearly surrounded by black. Upper surface 
of tail like the back with dark brown spots, a few narrow bands at 
the tip. Markings on head, neck and ears normal.
