A COLLECTION OF MAMMALS FROM SUMATRA. WITH A REVIEW OF 

 THE GENERA NYCTICEBUS AND TRAGULUS. 



BY WITMER STONE AND J. A. G. REHN. 



The Academy of Natural Science;* of Philadelphia has recently- 

 received, through the geuerosity of ^Ir. Alfred C. Harrison, Jr., 

 and Dr. H. M. Hiller, a valuable zoological collection from Suma- 

 tra, which was made by them during their exploration of the island, 

 from August to November, 1901. 



The mammals contained in this collection form the basis of the 

 present paper. The authors are also indebted to the U. S. National 

 Museum for the privilege of examining certain specimens in con- 

 nection with their study of the genus Nycticehus, the material 

 having been loaned by Mr. Gerrit S. Miller, Jr. , Assistant Curator 

 of Mammals. 



The Harrison and Hiller collection comprises sixty-five speci- 

 mens, secured mainly at Goenong Soegi, Lampong District, at an 

 elevation of less than 500 feet, and partly in the highlands of 

 Padang Bovenland, at Batu Sangkar, Tanah Datar, 1,500 to 3,000 

 feet. 



Sus vittatus Mull, and Schl. 



Sus vittaius Miill. and Schl., Vecli. I, p. 172, Pis. 20 and 32, fig. 5. 

 Two head skins and skulls, male and female, loaned for exam- 

 ination by Dr. Hiller appear to belong to this species. 



Tragulus napu (Cuv.). 



3/oschus napu (F. Cuvier), Hist. Nat. dcs Mum., IV, livre 37, 

 November, 1822. 



Three specimens, Goenong Soegi, Lampong District, October- 

 November, 1901. These agree very well with the figure in the 

 Hist. Nat. des Mavi.; the color of the dorsal surface, the limbs 

 and the sides agreeing very closely, the only difference being the 

 presence of a well-defined transverse gular bar which is absent or 

 else very faintly defined in the figure.
