While by its characters it falls into the same category as P.pileatus 

 in Blanford's Kej to the genus (Mammalia, p. 27), I can find 

 no specimen at all resembling it in the National Collection, nor 

 have I been able to trace any description that would fit it. Series 

 of specimens were obtained at Homalin and Hkamti, which diflfer 

 markedly in colouration. A single specimen taken at Minsin, half- 

 way between these two places, shows a somewhat intermediate 

 colouration. 



I propose therefore to describe the Homalin form as a new 

 species, under the name shortridgei and to rank the Hkamti form 

 as a local race of it, ander the name shortridgei helliger. The name 

 refers to the khaki coat assumed by the northern animal. 



Presbytis shortridgei, sp. n. 



A Langur of the larger, stouter schistaceus type ; most nearly 

 resembling P. inleatus, but entirely lacking the yellow in the 

 colouration of that animal. 



Size large, larger and stouter than any of the Burmese Leaf- 

 monkeys, such as P. ^phayrei. 



Fur long and silky, about 50 mm. long on the back, 100-110 

 mm. on the flanks. Hair of crown laid straight back from the 

 forehead, not radiating from one or more points, forming a " cap," 

 as in ijileatus. 



General colour above and below pale bluish grey (" cinereous "), 

 dorsal area much darker (" slate grey"), nape of neck paler, 

 silvery grey. Face naked, moustache and eyebrows black. A 

 white tuft on the points of the ears. (Mr. Shortridge notes that 

 this white ear tuft is very conspicuous in life). Limbs coloured like 

 flanks, hands and feet black. Tail like flanks for about 200-250 

 mm., remainder black. 



Skull as in P. fileatus. 



Dimensions of the type (recorded by the collector) : — Head and 

 body, 710; tail, 1,020; hindfoot, 196; ear, 35-5. Skull :— Great- 

 est length, 115; basal leng-th, 80; zygomatic breadth, 90; brain- 

 case breadth, 63 ; breadth across orbits, 78 ; interorbital breadth, 

 14; cheek teeth, behind the canine, 31. 



Habitat. — Homalin, Upper Ohindwin, Burma. 



Type . — Adult male B . M . No . 1 5 ■ 5 • 5 • 1 . Original number 5,714. 

 Collected by Messrs. G. C. Shortridge and S. A. Macmillan on the 

 17th July 1914, and presented to the National Collection by the 

 Bombay Natural History Society. 



Altogether 5 specimens were obtained (03f 02) at Homalin, and 

 a male from Minsin, about half-way between Homalin and Hkamti. 

 This last specimen is much less clear grey than those from Homa- 

 lin and is no doubt an intermediate.
