Chai'acters. — Externally like Tragulus Icmicliil. Skull slightly 

 larger and broader than in the Sumatran animal, and teeth notioeabl}^ 

 hea\ier. 



Color. — The color so closely resembles that of the Sumatran Irayn- 

 Ins kanchil that 1 can detect no constant differences between the two 

 animals. Among the specimens of T. carlmatx^ however, occur the 

 individuals with the underparts most strongly suft'used with huffy and 

 with the most heavily marked nape stripe. 



Sl'idl and teeth. — The skull does not differ very noticeably from 

 that of Tragidus kanchil^ except that the specimens average somewhat 

 larger and broader, as may be readih' seen on comparing series. The 

 differences in the size of the teeth of the two animals are shown in the 

 following table:"
