TARSIUS TARSIER (Erxleben). 



Four specimens of Tarsiers from western Borneo may be referred 

 to this species provisionally. The only skin preseryed, a female, is 

 practically indistinguishable from a Philippine skin (Cat. No. 105475, 

 U.S.N.M.), from Mindanao. The skulls of the Bornean specimens are 

 larger, with heavier teeth and more inflated bulla^ than has the 

 Philippine skull.

 ber 9, 190(). 



Five specimens from Sanggaii, one from Tyan, one from the Lan- 

 dak River, and two from the Sakaiam River. For measurements of 

 this and other species see Proceedings of the U. S. National Mu- 

 seum, XXXI, page 537. In his notes Doctor Abbott says: "Brought 

 in alive by Malays. Many of these animals are caught at this sea- 

 son (August) when tlie jungle is being felled for Jadangs (clearings 

 for paddy)." 



MACACA FASCICULARIS (Raffles). 



One skin and skull of an adult male, Cat. No. 142225. U.S.N.M., 

 from Sungei Sama, near Pontianak. 



Measurements: Head and body, 445 nmi.; tail, 570; hind foot, 140; 

 greatest length of skull, 119; zygomatic width, 77; maxillary tooth 

 row, 37.5; mandibular tooth row, 41.3. 



MACACA NEMESTRINA (Linnaeus). 



It is with much hesitation that I refer three skulls, without skins 

 to Macaca nemestrina. They were obtained by Doctor Abbott from 

 the natives, one from the Landak and two from the Sakaiam River. 

 Either the species is represented at these two places by two forms or 

 else the range of individual variation is considerably greater than the 

 specimens studied by Mr. Miller" would indicate.
