Several specimens of this form from the southern part of Malacca 

 are in the British Museum, resembling each other in the color 

 of their coats, much darker than those from the Straits Settlements 

 and lower parts of the peninsula, and more like P. obscura but with- 

 out the nuchal patch, and not so dark in color. They belong to the 

 white — or grayish — thigh group of these monkeys. These examples 

 had gone under the name of dbo-cinereus Desmarest, but that species 

 has "epaules, flancs, face externe du haut des bras et des cuisses d'un 

 gris clair; milieu du dos d'un gris un peu plus fonce," which in no wise 

 described any Sumatran Pygathrix that I have seen, and comes nearer 

 to P. AYGULA than any other. Eydoux and Souleyet in their work on 

 the voyage of the 'Bonite' describe and figure a monkey under the name 

 of albo-cinereus Desmarest, but which answers in no respect the 

 description that Author gives of his species, and which is evidently 

 the Semnopithecus obscurus Reid.
