174 Miller Ttco New Malayan Manse Deer. 



slightly paler than that of Ridgway. A narrow, very indistinct line of 

 this color divides color of sides from the pure white of underparts. In 

 axillary region this line widens to cover sides of chest and send back an 

 irregular and variable streak along middle of belly. Neck ochraceous, 

 less bright than that of legs and much sprinkled with black. Nape- 

 band ill-defined, black, considerably mixed with ochraceous. Throat 

 markings normal, the dark bands like sides of neck and well defined 

 collar slightly paler. Head and face like sides of neck, but ochraceous 

 less bright and black hairs more numerous. Tail white beneath and at 

 tip, dull ochraceous above. 



Skutt. The skull shows no characters worthy of note, except that in 

 size it distinctly exceeds that of Tragulus pallidus. 



Measurements. External measurements of the type: total length, 535; 

 head and body, 470; tail vertebrte, 65; hind foot, 120; hind foot without 

 hoofs, 108. Weight, 1.9 kg. An adult male from the type locality: 

 total length, 520; head and body, 445; tail vertebrae, 75; hind foot, 112; 

 hind foot without hoofs, 102. Skull of type: greatest length, 94; basal 

 length, 86; basilar length, 82; occipito-nasal length, 89. Skull of adult 

 male: greatest length, 93; basal length, 85; basilar length, 80; occi 

 pito-nasal length, 86. 



Specimens examined. Eight, all from the type locality. 



Remarks. This species is readily distinguishable from Tragulus kan- 

 chil by its pallid coloration, and from T. pallidus by its greater size. 



Tragulus borneanus sp. nov. 



Type. Aclult male (skull only) No. 34,924 United States National Mu 

 seum. Collected on the Suanlamba River, British North Borneo, by 

 C. F. Adams. 



Characters. In general similar to Tragulus napu from Sumatra, but 

 smaller and darker; toothrow longer than in the Sumatran animal. 



Color. Through preparation by means of an acid preservative fluid 

 the skins examined have been altered in color by the removal of most 

 of the red and yellow tints. The color pattern, however, remains un 

 changed. Underparts as in Tragulus napu, the middle of belly with a 

 dusky wash (probably rusty before action of acid) on tips of hairs. Up- 

 perparts with decidedly more black than in T. napu, the crown and 

 nape stripe nearly clear black, and the black clouding of the back much 

 more noticeable, in this respect suggesting T. pretiosus. 



Skull and teeth. The skull is distinctly smaller than that of Tragulus 

 napu, so much so that those of immature individuals suggest those of 

 T. kanchil. In general form there appear to be no tangible differences. 

 The ascending portion of the premaxillary is broader than in the Suma 

 tran animal, and the horizontal portion less produced forward. Teeth 

 actually as well as relatively larger than in T. napu, the difference par 

 ticularly noticeable in the lower premolars.
