cept that it is larger and the rostral portion is more elongate. Teeth 

 essentially as in the Sumatran animal, Chough the premolars appear to 

 be less robust. 



Measurements. External measurements of type (from well made skin): 

 total length, 560; head and body, 470; tail vertebrae, 90; hind foot, 31.4 

 (19); ear from meatus, 35.6; ear from crown, 29. 



Cranial measurements of type: greatest length, 98 (92)*; basal length, 

 90 (86); basilar length, 86 (79); occipito-nasal length, 92 (88); length of 

 nasals, 30.6 (30); greatest breadth of both nasals together, 13.8(13.4); 

 diastema, 11 (7); zygomatic breadth, 42 (40); least interorbital breadth, 

 27 (26); mandible, 75 (70.6); maxillary toothrow (alveoli), 32 (31); max 

 illary premolars (crowns), 15.4 (16); mandibular toothrow (alveoli), 36.4 

 (36); mandibular premolars (crowns), 16 (16.4). 



Specimens examined. Three, the type from Mount Dulit, an adult 

 male from Kinabatigan River and a female from the neighborhood of 

 Sandakan. 



Remarks. The two specimens from British North Borneo have been 

 so injured by the action of a preservative fluid that their color cannot 

 be compared with that of the type. The color pattern is r however, the 

 same. In general color the Bornean kanchil is not unlike Tragulus 

 ravus of the Malay Peninsula, but the back is more heavily clouded 

 relatively to the sides, and the nape stripe is of a very different charac 

 ter. In Tragulus kanchil the black clouding on both back and sides is 

 noticeably in excess of the light element in the color, while in the 

 Bornean animal this is true of the back only and even here to a distinctly 

 less degree than in the Sumatran form.

Characters. In general similar to Tragulus kanchil T but smaller (hind 

 foot of females 112-118 mm.) and more yellow. 



Color. The color pattern in all its details exactly resembles that of 

 Tragulus. kancJiil but the ground color of upperparts is bright tawny- 

 ochraceous instead of yellowish buff, and the black clouding is not in 

 excess of the ground color. Nape band, broad and conspicuous, slightly
