72 PYGATH RIX 
Semnopithecus cephalopterus (!) white var., Anders., Zool. Res. 
Exp. Yunnan, 1878, p. 23, (footnote). | 
Type locality. Ceylon. 
“C. barbatus totus albus” Erxl. 
A white monkey from Ceylon was described in the above terms by 
Erxleben, (1.c.). Blanford (1. c.) describes P. senex as follows: “Fur 
dense and wavy, whiskers full. Long white hairs over the toes.” 
“Color. Yellowish white, faintly marked with brownish on the 
head, dusky over the shoulders and on the middle of the back. Face 
and ears black. Soles and palms flesh-colored.”’ 
“Dimensions. Apparently the same as those of S. ursinus. 
“Distribution. Mountains of Southern Ceylon at considerable 
elevations.” 
Blanford does not state from what specimen he took his descrip- 
tion, but does say that the only one he had seen was “a young animal 
in the Leyden Museum which Schlegel says came from Temminck’s 
Collection and was brought from Ceylon at the end of the last century,” 
(1700). His description does not exactly agree with Blanford’s. “Sa 
teinte dominante, d’un blanc jaunatre, est lavée de brun sur le dos, et 
de roux sur le dessus de la téte et la nuque.” No example from Ceylon 
answering Erxleben’s description is known so far as I am aware, 
and it was probably an albino of P. ursina, or P. CEPHALOLOPTERA, — 
or the one described by Kelaart as P. montTicoxa, but which one of 
these can never now be known, and therefore senex Erxl., being unde- 
terminable must be dropped from the list. Should a third species of 
PyGaTHRIx be discovered in Ceylon, it probably will be ascertained 
to be the one described by Kelaart as PRESBYTIS MONTICOLA.
