2 SMITHSONIAN MISCELLANEOUS COLLECTIONS [voL. 45 



which are represented more than thirty hitherto undescribed species. 

 Five of these are monkeys, two of which, a dwarf siamang and a 

 member of a new genus Simias, differ from their known rela- 

 tives by very remarkable characters. Study of these collections has 

 led to the reexamination of much of Dr. Abbott's material that has 

 been previously reported on. The seventy new mammals here de- 

 scribed have been found in the course of this work. 



TRAGULUS BATUANUS sp. nov. 



Type. — Adult female (skin and skull). No. 121,697, United States 

 National Museum. Collected on Tana Bala, Batu Islands, Sumatra, 

 February 5, 1903, by Dr. W. L. Abbott. Original number, 2226. 



Characters.- — A large member of the Tragiilus napu group with 

 wholly black neck and black throat stripes. The black of neck ex- 

 tends forward over face and cheeks more than in any other species 

 except Tragiilus amice, T. jugularis, and T. hunguranensis. From 

 all of these the Batu animal is distinguished by the normal pattern of 

 the throat markings. 



Color. — Type : back ochraceous heavily shaded by the black hair- 

 tips, neither color distinctly in excess of the other. On sides the 

 ochraceous fades to buff and the black shading becomes slightly 

 less heavy than on back. IMuzzle, loral stripe, face, except dull 

 ochraceous line 4 mm. wide bordering loral stripe, crown, ears, 

 entire neck to outer white throat stripes, and cheeks to level of 

 posterior canthus of eye, glossy black. Cheek from muzzle to pos- 

 terior canthus of eye dull grizzled ochraceous. On close inspection 

 dull ochraceous annulations may be detected on the black portion 

 of the cheeks and on the neck, particularly at sides. These are 

 nowhere sufihciently numerous to break the clear black effect, ex- 

 cept at front of shoulders, where they rapidly increase in number, 

 producing a rather abrupt transition to the color of the back. 

 Underparts and light throat stripes white. A brownish stripe 

 60 mm. long and 4 mm. wide on middle of chest. Dark throat 

 stripes clear black ; collar black, noticeably speckled with dull 

 ochraceous. The throat pattern is in every way normal, though the 

 black stripes are perhaps narrower than usual. At anterior termi- 

 nation these stripes are about 10 mm. apart, and there is no brown 

 wash on the white in front of them. Legs like back externally, 

 the inner surface white. On hind legs the white disappears at about 

 middle of tarsus ; below this point the legs and feet are sprinkled 

 with dull ochraceous hairs. Tail like back above, but ochraceous 

 not as bright, white below and at tip.
