34 Miller — Eleven New Malayan Mouse Deer. 



Measurements. — External measurements of type: total length, 600; 

 head and body, 520; tail vertebrae, 80: hind foot, 132 (117); ear from 

 meatus, 37; ear from crown, 34. Skull: greatest length, 105; basal 

 length, 98; zygomatic breadth, 44. 



Weight.— 3 kg. 



Specimens examined. — One, the type. 



Remarks. — In the character of its neck and throat markings Tragulus 

 flavicollis agrees with the small, bright T. rufulus of Tioman Island and 

 represents the opposite extreme from Tragulus anna, in which the en- 

 tire region is clear black. It only remains to discover species with the 

 white of the throat obliterated by the encroachment of fulvous on the 

 white bars to complete the possible variations of this pattern. 



Tragufus formosus, sp. nov. 



Type. — Adult male (skin and skull) No. 115,511 United States National 

 Museum. Collected on Pulo Bintang, Rhio Archipelago, August 19, 

 1902, by Dr. W. L. Abbott. Original number 1907. 



Characters. — A member of the tiapu group similar in general appear- 

 ance to Tragulus pretiosus of Linga Island, but with dark nape stripe 

 less defined, fulvous of neck and throat more red, and underparts usu- 

 ally more washed with yellowish. Premolars larger than in T. pretiosus. 



Color. — Type: Upperparts bright orange-ochraceous darkening to och- 

 raceous-rufous on neck and outer surface of legs and lightening to orange- 

 buff on sides of body, the hairs everywhere drab at base and black at 

 tip. The black tips are most conspicuous over middle of back, where 

 they produce a heavy dark shading a little in access of the orange-och- 

 raceous. On sides of body they are slightly less noticeable, and on 

 sides of neck and head and outer surface of legs would readily escape 

 observation. Crown and median line of neck black, both heavily 

 sprinkled with ochraceous-rufous, the nape stripe so much so as to form no 

 striking contrast with surrounding parts. Superciliary stripe distinct, 

 about 7 mm. wide above eye, concolor with cheeks and sides of neck. 

 Muzzle and ears blackish. Throat markings normal, the hairs of the 

 dark bands blackish at base and heavily annulated with bright ochra- 

 ceous-rufous. Collar narrow but distinct, its color intermediate between 

 that of neck and sides of body. Underparts much like sides, but with 

 a drab cast, except a pure white area on chest and another on hypogas- 

 tric region, the former partly divided by a narrow brownish median 

 line. The posterior white area is continued down inner side of hind 

 legs, but that on chest is separated from white of inner surface of front 

 legs by a narrow yellowish drab line. Tail ochraceous-rufous above, 

 pure white below and at tip. 



Skull and teeth. — I cannot see that the skull differs from that of 

 Tragulus pretiosus. The permanent premolars both above and below, 

 are, however, distinctly larger than in the related animal.
