34 PYMGATHRI X 
body and arms, general color ochraceous, the hairs being ochraceous 
buff tipped with brown, this giving a darkened hue to the general 
effect ; outer surface of legs bright ochraceous rufous, with a dark line 
of the same color from knee on to thigh; entire under parts and inner 
side of limbs yellowish white; hands and feet ochraceous rufous; tail 
above like the back, but becoming a clearer ochraceous rufous towards 
the tip, beneath paler for basal half, remainder like upper parts.

The type of S. favimanus Geoff., is no longer in the Paris Mu- 
seum, but there is an example labelled with that name, presented by 
M. Diard but without date. It is in very good condition although faded 
somewhat in the lighter colors, and cannot be separated from P. 
MELANOLOPHA. 
Semnopithecus ferrugineus Schleg., (1. c.) is represented in the 
Leyden Museum, all the examples immature, and among them the one 
figured in Muller and Schlegel’s work (1. c.). I can see no reason to 
separate these from P. MELANOLOPHA, as they seem to grade gradually 
into the pelage of the adult of that species, and slightly older specimens 
recognized as P. MELANOLOPHA differ from S. ferrugineus Schleg., 
only in the crest and back having turned a little darker, progressing 
to the brownish back of P. MELANOLOPHA.
