TRAGULUS RUSSEUS, new species. 



Type.— MuM iiialo (.skin and skull), Cat. No. 114337, U.S.N. M. 

 Collected on Pulo Tuangku, Banjak Islands, February 15, 1902, by 

 Dr. W. L. Abbott. Original number, 1518. 



Characters. — Size and general appearance as in Tragulus fulvlmnter 

 Gray," but brown throat stripes not as dark and white stripes often 

 obsolete and occasionally absent. 



Color. — Type : (xeneral color above orange-ochraceous, slightly paler 

 on sides and darkening to raw sienna on neck and outer surface of 

 limbs. The hairs of the back are tipped with black, which, when the 

 fur is undisturbed, form^ a dark shading decidedly in excess of the 

 orange-ochraceous. Across shoulders this shading deepens rapidly 

 into the clear black nape stripe. On sides of body and neck the lighter 

 color is in excess of the black, which practically disappears along lower 

 edge of sides, where the color passes into the clear raw sienna of legs 

 and very pale orange-ochraceous with which the under parts are suf- 

 fused. Crown blackish, strongly grizzled with yellowish brown. 

 Cheeks distinctl}^ paler than neck, the exact color intermediate 

 between the })uff-}' ellow and straw-yellow of Ridgway. Muzzle darker 

 and duller than cheeks. An indistinct pale line borders dark color of 

 crown from ear to nuizzle. Ears blackish. Chest and belly pale 

 orange-ochraceous, fading nearly to ochraceous buff in axillary region, 

 and with white markings as follows: (1) A large patch in h^^pogastric 

 region, continued downward along inner side of hind legs and forward 

 as two narrow stripes to about level of diaphragm; and (2) a narrow 

 stripe on each side of median line of chest. Chin white to about 10 

 mm. behind median bare area, the posterior outline of the white nearly 

 straight, and 55 mm. in length. Behind this the region usually occupied 

 by the white throat stripes presents a peculiar mottled aspect, due to 

 the fact that the white is mostly replaced by clear orange-ochraceous, 

 which forms no distinct contrast with the collar and dark stripes, both 

 of which are essentially like sides of neck, therefore distinctly grizzled. 

 The white persists as a semilunar spot 20 mm. wide by 10 mm. long (the 

 concavity directed backward), the remnant of the posterior extremity 

 of the median stripe, and a very faint, easily overlooked trace of each 

 of the lateral stripes. The collar sends back a dark median stripe 90 

 mm. in length between the two white chest stripes. Inner surface of 

 front leg with a few whitish hairs, not enough to produce a white 

 area. Tail white beneath and at tip, concolor with flanks above. 



While the type represents the more extreme phase of the species, one 

 specimen (female Cat. No. 111336, U. S.N. M., original number 1507), 

 carries the peculiarities much further. In this the white is all replaced
