SEMNOPITHECUS vez PRESBYTES. 23 
Dr. Anderson considers this monkey as identical with Semnopithecus 
priamus, but Kellaart, as I have before stated, is very positive on the 
‘point of difference, calling S. A77amus emphatically the crested monkey, 
and alleging that ¢hersites has no crest, and it is probable he had oppor- 
tunities of observing the two animals in life; he says he had a young 
specimen of Jriamus, which distinctly showed the crest, and a young 
thersites of the same age which showed no sign of it. 
In Emerson Tennent’s ‘ Natural History of Ceylon,’ (1861) page 5, 
there is a plate of a group in which are included priamus and thersites ; 
in the original they are wrongly numbered—the former should be 2 and 
not 3, and the latter 3 and not 2. If these be correct (and Wolfs name 
should be a voucher for their being so) there is a decided difference. 
Thereis no crest in the latter, and the white whiskers terminate abruptly 
on a level with the eyebrow, and the superciliary ridge of hair is wanting. 
No. 16. SEMNOPITHECUS ve/ PRESBYTES ALBINUS (Xce//aa7‘?). 
The White Langur. 
Hasirat.—Ceylon, in the hills beyond Matelle. 
DESCRIPTION.—Fur dense, sinuous, nearly of uniform white colour, 
with only a slight dash of grey on the head ; face and ears black ; palm, 
soles, fingers and toes flesh-coloured; limbs and body the shape of 
P. ursinus ; long white hairs prolonged over the toes and claws, giving 
the appearance of a white spaniel dog to this monkey; irides brown; 
whiskers white, full, and pointed laterally —Kel/aart. 
The above description was taken by Dr. Kellaart from a living 
specimen. He considered it to be a distinct species, and not an Albino, 
from the black face and ears and brown eyes. 
The Kandyans assured him that they were to be seen (rarely how- 
ever) in small parties of three and four over the hills beyond Matelle, 
but never in company with the dark kind. 
Emerson Tennent also mentions one that was brought.to him taken 
between Ambepasse and Kornegalle, where they were said to be nume- 
rous ; except in colour it had all the characteristics of P. cephalopterus. 
So striking was its whiteness that it might have been conjectured to be 
an Albino, but for the circumstance that its eyes and face were black. 
An old writer of the seventeenth century, Knox, says of the monkeys 
’ of Ceylon (where he was captive for some time) that there are some 
‘‘milk-white in body and face, but of this sort there is not such plenty.” 
—Tennent’s ‘ Natural History of Ceylon, page 8. 
Note.—Since the above was in type I have found in the List of Animals in the 
Zoological Society’s Gardens, a species entered as Semmnopithecus leucoprymnus, the 
Purple-faced Monkey from Ceylon—see P.Z.S.
