ANDERSON'S LANGUR. 



Type locality. Unknown. 



Measurements. "Total length 3 feet, 9.60 in." 



"Uniform dark slaty gray, passing into black on the forearm and 

 hands, and also on the feet. Upper parts, and inside of hind limbs 

 and thighs pale yellowish gray. Head slightly crested over vertex, but 

 only with a feeble tendency to lateral compression. Supra orbital hairs 

 moderately long, and black; whiskers rather long, directed backwards 

 and outwards, hiding the ears in front. Face bluish black ; area around 

 the eyes and the lips white. 



"The nasal region of the skull is rather prominent, nearly straight 

 and moderately broad, with the orifice narrow and rather long. Supra 

 orbital ridges are well developed, and the orbits are nearly round and 

 of moderate size. The premaxillaries form a slightly expanded suture 

 with the nasals. The last mentioned bones are about half the lateral 

 length of the premaxillaries. The palate has moderately broad margins 

 very slightly posteriorly convergent." 



The type of this form in the Calcutta Museum where it was sup- 

 posed to be, although Anderson gives no information on this point, 

 was not found. No locality was given by the describer for his speci- 

 men, nor beyond the description does he give any information about 

 it. It probably will prove to be the same as P. barbei to which 

 species Anderson's description given above, shows it bears a close 

 resemblance.
