But in Celebes both varieties are living together. 



If this supposition be right, we may only speak of Macacus mau- 

 rus F. Cuvier (1823), as this is the older narae with the synonym 

 ocreatus Ogilby (1840). 



This question is not without real importance. 



There are known only three species of Macacus, very remarkably 

 characterized by an extremely short tail and a simply coloured für. 

 One of them, M. arctoides, from Burma to Cochinchina, is by its red 

 face strongly distinguished from the two others. These : Macacus mau- 

 ras and ocreatus have black faces and are also in other respects very 

 different from M. arctoides. Is my supposition right, that both are 

 variations of one species, both only living in Celebes, tuen Celebes 

 has one extremely characteristic animal more. With Babirusa alfurus, 

 Cynopithecus niger, Anoa depressicornis, Paradoxurus musschen- 

 broekii, — Macacus maurus F. Cuv. (ocreatus Ogilby) is one more 

 of these remarkable animals peculiar only to that island with a Con- 

 tinental character. 



Prosimiae. 



Nycticebus. 



Nycticebus tardigradus Fischer. 



Sumatra: Singkarah and Solok; four specimens (106, 144, 146, 620). 

 The weight of the brain I found in one specimen as follows : 

 cT n°. 106. head and body .... 31,5 cm. 



tail .... 1,5 cm. 

 weight of body .... 500 gr. 

 weight of brain .... 8,8 gr. 

 The proportion of the weight of brain to the weight of the body 

 is 1,63%. 



Carnivora.

Felis tigris Linne. 



Sumatra: Fort de Kock; skull (206). 

 Java : Preanger Regendes ; skull (283).
