the so-called P. nobilis, Gray; while it is likely that there is a melanoid 

 phase of P. rubicundus of Borneo.* 



Before seeing the coloured drawings sent by Professor Peters, I suspected 

 that P. chrysog aster would prove identical with P. pileatus, Blyth,f which 

 is common in the hills bordering on Sylhet and those of Tippera and 

 Chittagong, and the old males of which are deeply tinged with ferruginous 

 on the lower parts. Pemales and young have the lower parts white or but 

 faintly tinged with ferruginous, and the rest of the coat is of a pure grey, 

 the face black, and there is no crest, but the hairs of the crown are so 

 disposed as to appear like a small flat cap laid upon the top of the head. 

 The old males seem always to be of a deep rust colour on the cheeks, 

 lower parts, and more or less on the outer side of the limbs; while in 

 old females this rust colour is diluted or little more than indicated* A 

 mature male which I possessed alive was an exceedingly gentle animal, 

 and the species is akin to P. maurus of Java, though so different in colouring. 

 It is likely to occur in the northern part of Arakan.

This species is closely allied to, if not identical with, P. femoralis, 

 Horsfield (=P. chrysonielas, Tern.), of the Malayan peninsula and Sumatra, 

 the female of which is figured of a brown colour by MM. Temminck and S. 

 Muller ; but adults of both sexes described as P. lar bet, from skins, minus 

 the skull, procured in the interior of the Tippera hills, were black. 

 The colour is probably variable. According to Cantor, the face during 

 life is intense black, except the white-haired lips and the chin, which are of 

 a milk-white colour. It is another likely species to occur in the Indo- 

 Chinese region; and from the Malayan peninsula Dr. Cantor gives four 

 species of this genus, viz. P. cristatus, P. femoralis, P. obscurus, and 

 P. melanosis ; while the remarkable and very handsome P. nemceus was 

 observed plentifully in Cochin-China by Crawfurd, whence also has lately 

 been described and figured P. nigripes, Ad. Milne-Edwards. £ M. Milne- 

 Edwards, jnn., has also figured and described BMnopithecus roxettana, a 

 very remarkable animal of this group from the same forests of Eastern 

 Tibet as are inhabited by Macacus tibetanus. 



* In the Calcutta Museum there is a brown specimen of the common P. cephalopteras 

 of Ceylon.
