(Published by permission of the Trustees of the British Museum.) 



The National Museum owes to the authorities of the Selangor 

 Museum, and especially to Mr. H. C. Robinson, a further 

 magnificent collection of mammals of all groups, and of these 

 a full account is being forwarded to the ' Journal of the 

 Federated States Museums.' In the meantime, however, to 

 avoid clashing, it is thought better that the following 

 diagnoses should be published at once.

A local race of P. cristata, characterized by its darker 

 colouring, especially on the forehead and forearms, and its
