Races of Tragulus kancliilj Raffles. 295 



wliile it lacks the irregular transverse band across the vent. 

 I am doubtful if there is any specific value attaching to these 

 markings of the underparts, but perhaps it is as well that 

 they should be noted. 



If we turn to the skull we find that T. fulviventer is inter- 

 mediate in form between T. afflm's and the present subspecies. 

 It is intermediate in size, intermediate in the constriction of 

 the basioccipitalj and intermediate in the amount of swelh'ng 

 undergone by the bulla?. The pra3maxilla^, however, are of 

 the T. Hosei type. The maxillary tooth-row is precisely the 

 same length in all three forms, and in the case of T. affinis 

 and T. Ilosei the teeth are practically alike, but in T. fuhi- 

 venter there is a curious change, which I take to be merely an 

 individual variation. The second molar in the upper jaw on 

 either side is considerably broader, measuring 7 millim., as 

 against 5 millim. in T. Hosei^ and the last molar is reduced 

 to a single conical cusp. 



Tragulus kanchil Everetti, subsp. n. 



Appearance similar to T. k. Hosei, but deeper in colour 

 and rather smaller. 



General colour like T. Jc. Hosei, except that the red on the 

 flanks is much deeper, being rufous ('* ochraceous rufous," 

 Kidgw.) instead of deep buff (" orange-rufoas," Kidgw.). 



Underparts pure white, with the exception of one long 

 median ventral stripe, broad and of an orange colour over the 

 belly, but nairow and grizzled anteriorly. There is a very 

 faint trace of the transverse abdominal band, and a patch of 

 orange on the thighs narrows down the white to a thin stripe. 



The skull, which is slightly smaller than that of T. k. 

 Hosei, may be at once distinguished by its large teeth and 

 small bullae. The prsemaxill^, instead of sloping gradually 

 downwards after leaving the nasals, as in T. affinis, or 

 narrowing abruptly, as in T. Hosei. continue forwards at 

 tiieir original breadth for some 3 millim., and then suddenly 

 turn down abruptly. In other respects the skull does not 

 differ from that of T. k. Hosei.
