Specimens belonging to this species are very rare in 

 Zoological collections , the only specimens to be found in 

 Musea are, as far as I am aware, the type-specimens in 

 the British Museum from Horsfield's collections from Java, 

 and a nearly adult male in the Leyden Museum collected 

 in 1860 by Professor de Vriese, with the exact locality, 

 district Baton , Passarouan-residence , East-Java. 



In his well known »Simiae" Schlegel observed that S. 

 pyrr/ius is distinguished from *.S. mawrws: >parce qu'il garde,

 »les ongles d'un jaune blanchatre et non pas bruns." 



Professor Hubrecht on his journey in the Malayan Ar- 

 chipelago had the good luck to come across several spe- 

 cimens of this species and has brought home skins of an 

 adult, of a half-grown and of a young individual, besi- 

 des skeletons. They have been collected close to the lo- 

 cality where Professor de Vriese procured the above men- 

 tioned specimen, namely in the Bezoeki-residence , between 

 Djember and Poeger. 



I have nothing to add to Schlegel's description of the 

 color of the specimens , old and young presenting the ty- 

 pical red , somewhat lighter however because they have 

 been preserved in spirits. According to the value ascribed
