differences, however, between them. The necks of the Bornean speci- 

 mens are perhaps not so brightly colored as are those of the Sumatran 

 examples. Only one Bornean skin, Cat. No. 153740, from the Ken- 

 dawangan River, has a distinct yellowish coloration, resembling the 

 Tragulus fulvicollis x type, instead of several such specimens, as in the 

 case of the Sumatran series. The length of hind foot, including the 

 hoof, is essentially the same in the two series, and it is distinctly longer 

 than it is in the typical Sumatran kanchils from Aru Bay and Tapanuli 

 Bay. (See table of measurements, p. 68.) A careful study of this 

 table shows that the range of variation of the Bornean skulls is slightly 

 greater than that of typical Jcanchil skulls from Sumatra ; and that the 

 skulls of males and females in Borneo are of essentially the same size, 

 the males showing, however, more variation. In the Sumatran scries, 

 on the contrary, the skulls of females average larger than do those of 

 the males. 



The relationship of the present series of kanchils from southwestern 

 Borneo with Tragulus hosei (Bonhote) 2 of northern Borneo is not at 

 all clear. The latter species is represented in the National Museum 

 by the type of T. virgicollis Miller 3 and two poor skins, badly made 

 up and much discolored by a salt-and-alum pickling fluid, from north- 

 ern Borneo. The skulls of these three specimens are indistinguishable 

 from skulls of T. Jcanchil or T. Jcanchil longipes. The skins, however, 

 show the nape stripe to be darker, narrower, and better defined than 

 it is in any of the Sumatran or west Bornean specimens. The Mount 

 Dulit specimen has rather long hind feet; the hind feet of the other 

 two from north Borneo appear shorter, but reliable measurements can 

 not be taken from them. 



At present, judging by the material at hand, I believe that three 

 forms of small Tragulus occur in Sumatra and Borneo : T. Jcanchil 

 Jcanchil, from northern and western Sumatra; T. JcancJiil longipes, 

 from the swampy lowlands of eastern Sumatra and the swampy low- 

 lands of western and southwestern Borneo; T. JcancJiil Jwsei, from 

 northern Borneo.

Four specimens of a kanchil taken on Pulo Panebangan may be 

 referred to Tragulus carimatx Miller. The skins average darker and 

 the nape stripe wider and darker than they do in specimens from the 

 mainland of Borneo. Of the four specimens only one is adult. It
