PYGATHRIX HOLOTEPHREA (Anderson). 
Semnopithecus holotephreus Anders., Zool. Res. Exped. Yunnan, 
1877, p. 27; Id. Cat. Mamm. Ind. Mus. Calc., 1881, p. 50;

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.
