Larger and more powerful than the Indian M. rhesus, with longer and more 

 richly coloured fur. In the male, dark, rich, olive-yellowish, with a tint of slaty 

 olive on the head, neck, and anterior half of the trunk, brick-red on the hinder 

 quarters, the slaty olive of the extremities passing almost into black on the hands 

 and feet. Under parts greyish. The female is a brilliant fawn, with a tinge 

 of reddish, this colour being most marked on the hind quarters. Pace in both 

 sexes flesh-coloured, richest in the female. Tail of the latter about one-fourth 

 the length of the body. 



The type of M. lasiotis^ Gray,^ is said to have been procured from the province 

 of Tse-chuen, but the circumstance that it was a captive during the greater part of 

 its life somewhat detracts from its value as an example of the rhesus-like monkey 

 of that portion of China. 



The measurements of the skin now in the British Museum prove that it must 

 have been about the same size as M. assamensis, as it measures 25*3 inches from the 

 muzzle to the root of the tail, a fragment of which only exists, as has been conclu- 

 sively shown by Dr. Sclater.^ 



The characters of this monkey prove it to be closely affined to M. rhesus, but at 

 the same time the leading features of M. rhesus are so modified that it is apparently 

 entitled to rank as a species seemingly attaining to a greater size. The fur is 

 long, fine, and silky, longest on the shoulders, neck, and upper surface of the feet. 

 The annulation of the hair has, however, the same character as in Bengal examples of 

 3f. rhesus. The basal portion is slaty, while the sub-terminal band is rich orange or 

 brick-red, but the latter colour is more brilliant than in the Indian monkey, more 

 especially on the hinder quarters, where it is so intense as efi'ectually to obscure 

 the underlying slaty and the narrow black tips, but on the shoulders, neck, head, 

 and on the fore-legs it is not so marked, and does not hide the underlying slaty 

 colour of the fur which, mixed with the paler orange-red bands, confers a slaty-olive 



According to the short account which has been published of this species, it differs from C. niger in being of a 

 brownish black tint, most prevalent on the shoulders and back. The ischiatic callosities are also stated to differ 

 from those of C. niger. 



Inhabits Celebes, Moluccas, and the small adjacent Island of Batchian, into which Mr. Wallace considers it has pro- 

 bably been introduced, Proc. Zool. Soc. 1864, p. 276.
