34 PYGATHRIX 



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. 



Measurements. Total length, 1,110; tail, 650; foot, 160, (skin). 

 Skull: total length, 99.2; occipito-nasal length, 80.4; intertemporal 

 width, 40; Hensel, 31.6; zygomatic width, 74.8; breadth of braincase, 

 55 ; length of upper molar series, 26.8 ; length of mandible, 73.5 ; length 

 of lower molar series, 31.7. 



Female. Skull in Paris Museum. Total length, 99.7 ; occipito- 

 nasal length, 87.8; intertemporal width, 46; breadth of braincase, 57.2;

The type of 5". flavimanus 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 Miiller 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.
