SYSTEMATIC LIST OF SPECIES. 

 Family TRAGHLID.E. 



TRAGULUS NAPU ( F. Cuvier) . 



1822. Moschus 7iapuV. Cuvier, Hist. Nat. des MauiniilV'res, IV. I't. 37, []>. 108], 

 November, 1822; Sumatra. 



An adult male and three immature specimens were taken at Tapa- 

 nuli Bay. (For measurements see table, page 442.) These are the 

 first representatives of the species received b^^ the United States 

 National Museum. In all respects they agree with those recently 

 recorded by Stone and Rehn" from the Lampong district.'' Tragvlns 

 napu proves to be a grayish animal quite distinct from T. pretiosus 

 and T. ntgricoUis^ but somewhat closely resembling T. ea/iesee/is of 

 the Malay Peninsula. The general appearance is well indicated Iw the 

 larger figure on Cuvier's plate. 



TRAGULUS AMCENUS, new species. 



Type.— Adult male (skin and skull), Cat. No. 114563, U.S.N.M. 

 Collected on Pulo Mansalar, off Tapanuli Ba}' , Sumatra, March 8, 1902, 

 by Dr. W. L. Abbott. Original number, 1632. 



Characters. — A yellowish, dark-necked member of the napu group, 

 somewhat closely resembling Tragidas nigricoJJix^ of Sinkep Island, 

 but smaller and more richly colored. Throat pattern normal, the dark 

 stripes blackish. 



Color. — Type: Upperparts orange ochraceous, darkening toward 

 ochraceous rufous on outer surface of legs, and lightening to a buff 

 considerabl}" yellower than that of Ridgway on sides, the hairs every- 

 where pale ecrudrab at extreme base and black at tip. The black tips 

 produce a heavy shading on both back and sides. On the former it is 

 slightly in excess of the orange ochraceous, but on sides the two colors, 

 as seen in the skin, are about equally mixed. Throughout, the grizzle 

 caused by the contrasting colors is more coarse and conspicuous than in 

 Tragulus pretiosus, a difference which may prove to be seasonal. Neck 

 mostly black, this color clear and unmarked immediately behind occiput, 

 but elsewhere speckled with dull tawny ochraceous. At sides this 

 speckling is rather conspicuous, but on dorsal surface it is not ver}^ 

 noticeable except posteriorly. Crown black, slightly speckled with dull 

 tawny ochraceous anteriorly. Cheeks and the usual superciliary stripe 

 dull tawny ochraceous, slightly grizzled with black. Throat markings 

 normal, the dark bands black, slightly speckled with tawny ochraceous;
