302 MESSRS. O. THOMAS AND R. C. WROUGHTON ON [ Mar. 16, 
mostly too faded and deteriorated to be of much practical use 
in making comparisons. 
For the present magnificent addition to the National Collection 
we have every reason to be most grateful to Mr. Balston, to 
whom we were already so heavily indebted for his W. Australian 
donations. 
We have appended to the species Mr. Shortridge’s notes on 
their habits, native names, and distribution.

‘* Local, apparently confined to the mountains of West Java; 
where it occurs its presence is easily detected by its continuous 
ery, which carries a long distance and of which its native name 
is an imitation.”—G. C. 8.

A comparison of this fine series, all black specimens, with the 
co-types of Horsfield’s “ Semnopithecus pyrrhus” does not confirm 
the conclusions as to the specific distinctness of the black and red 
forms of the group published by Dr. Jentink*. The skull of 
No. 22.4, one of the co-types of the red form, is exactly matched 
by Mr. Shortridge’s No. 615, a black “mawrus,” in all the 
characters mentioned by Dr. Jentink, namely the size of the teeth, 
the degree of prognathism, the length of the palate, and the form 
of the chin. And the series shows that there is a good deal of 
variation in all of these characters. We are therefore compelled 
to adhere to the usual conclusion (which is confirmed by 
Mr. Shortridge’s note) that the red monkey named pyrrhus by 
Horsfield is an abnormal red form of the usual black animal that 
has gone by the name of maurus or maura. 
But, so far as names are concerned, the specific term maura 
Schreber, which has hitherto been used for this animal, should 
give place to pyrrha. For the primary basis of Schreber’s 
maura was the ‘* Middle-sized Black Monkey” of Edwards, whose 
plate and description show that it was not this species at all, 
but a West African Mangabey, possibly Cercocebus fuliginosus 
EK. Geoff. 
We do not think the evidence for the identification of Geoffroy’s
