effect. Underparts (except throat) and inner side of legs to heel 

 white. A dusky shade along median line of belly. Throat like neck, 

 but with a narrow white median sti'ipe, and on each side a well devel- 

 oped white lateral stripe. A white patch beneath each jaw. Tail 

 white beneath and at tip. Ears and naked parts of muzzle, face and 

 legs blackish in dried specimen. Hoofs horn color. 



Skull. — The skull is essentially similar to that of the specimen of 

 T. 7iapit from Linga Island. 



Teeth. — Teeth as in Tragulus napii with the exception of the mid- 

 dle upper premolar of the permanent dentition. In this the inner root 

 is equidistant from each of the outer roots, with the posterior of which 

 it Is nearly in line. The bases of the three roots therefore stand at the 

 corners of a nearly equilatei'al triangle. The resulting form of the 

 crown is quite different from that in the other large species of the 

 genus. 



Measurements. — External measurements of type : total length 

 534 ; head and body 464 ; tail vertebrae 70 ; pencil 30 ; hind foot 1 30 

 (107) ; ear from meatus 31 ; ear from crown 27; width of ear 31. 



Cranial measurements of type: greatest length 104; basal length 

 97; basilar length 91 ; occipito-nasal length, 96; length of nasals 39; 

 breadth of nasals anteriorly 9 ; breadth of nasals posteriorly 1 1 ; 

 median length of bony palate (measured from tip of premaxillary) 

 64; width of palate between anterior premolars 14; width between 

 posterior molars 15; diastema 9 ; zygomatic breadth 46 ; least inter- 

 orbital breadth 36.4; breadth between outer edges of paroccipital 

 processes 38; greatest length of audital bulla 20.4; greatest width of 

 audital bulla 1 3 ; distance between anterior extremities of audital 

 bullae 10; least distance between audital bullae 6.S ; depth from 

 parietal to lower edge of audital bulla 38; depth from upper rim of 

 orbit to alveolus of last molar 32 ; depth of rostrum at middle of dia- 

 stema 18.6; mandible 81 ; maxillary toothrow (alveoli) 37 ; mandib- 

 ular toothrow (alveoli) 42. 



Remarks. — This is an insular form of the napu characterized by its 

 rich, bright, color, and by the peculiar form of the middle upper 

 premolar. It is doubtless confined to Tioman Island.

One specimen, an adult female, with much worn teeth was secured 

 on Tioman Island, October 3, 1899. Its measurements are as follows :
