All the upper parts are rufous, but this colour passes into blackish on the hands, 

 feet, and ears, and into brown on the upper surface of the tail. The hairs are grey at 

 their base, as in M. sinicus, and are annulated as in that species, but the difference of 

 colour that exists between the two is produced by the greater intensity and richer 

 colouring of the annuli of the individual hairs of M. pileatus. The under surfaces 

 generally are whitish. The forehead is sparsely covered with hair and wrinkled, and 

 the muzzle is narrow and prolongated, the colour of the nude parts being livid 

 fleshy, except along the lower lip, the margin of which is blackish. The hair on the 

 head is rather long, forming a radiated, and occasionally somewhat erect, tuft.

This species is closely allied to the Toque (Jf. sinicus), which it represents in 

 Ceylon, but the differentiation between the two forms has proceeded further than 

 between S. entellus and its insular representative, so much so that there is no 

 difficulty in recognising their individual peculiarities.

of the camphor forests of the mountaius of'that island. Its colour he characterised as grey with the under parts 

 pale and the ej'es yellowish hrown. 



Mr. Blyth renaarked of the foregoing skull that it was so young, the second true molars not having been developed, 

 as not to exhibit any special characteristic, and he observes of a living specimen of the small Formosau monkey which 

 had been sent to him by Swinhoe that it was a half-grown female, and that it differed in no respect that he could 

 perceive from the common M. radiatus of the peninsula of India, except in being a shade or two darker with a niu-res- 

 cent wash on the face and ears. 



Swinhoe, however, in 1863,1 observes, in writing of JIf. cydopis : "This, as far as I could learn, was the only 

 species of monkey in the Island of Formosa," so that it is probable he had discovered that the monkey res«mblino- M. 

 ladiatus had been taken thither in the coui-se of commerce.
