Pithecus shortridgei, Wr. 



I described this species so recently in this Journal (I.e.) that a 

 repetition is unnecessary here. I would however take this oppor- 

 tunity of recording that it has been suggested, especially by Mr. 

 Shortridge, that the modified colouring of my subspecies helli(/er 

 from Hkamti is due to wood smoke. The type of shortridgei is from 

 Homalin, 



Pithecus hrahma, sp. n, 



A l^angur resembling shortridgei, but at once recognisable by its 

 snow white whiskers. 



Size and fur as in shortridgei ; the head, shoulders and forearms 

 coloured cinereous quite as in shortridgei ; the lower back and 

 flanks modified by a buffy mixture to an indescribable smoky brown 

 colour. Tail very much as in shortridgei ; cheeks and whiskers, 

 which include the ears, snow white. Below the chest, throat and 

 chin whitish, the belly and especially the flanks buff or ochraceous 

 buff. Tail as in shortridgei, i.e., a few inches at the base like the 

 back and the rest black. 



Skull as in shortridgei, but all measurements smaller because it is 

 a less well developed animal, the teeth too appear to be slighter 

 though the length of the row scarcely differs from that in the type 

 of shortridgei. 



Dimensions of the type unfortunately are not recorded but the 

 measurement of the foot is about 190 mm. and I judge the other 

 body dimensions are very much as in shortridgei. 



Skull: — Greatest length, 110; basal length, 77; zygomatic 

 breadth, 59; breadth across orbits, 69 ; interorbital breadth, 10; 

 cheek teeth, behind the canine, 29. 



Habitat. — Lakhimpur, Upper Assam.

Though intermediate in its general colouring between shortridgei 

 and djurga the striking snow white whiskers of hrahma sejDarate it 

 sharply from both.
