on each side, and is formed by the 

 backward extension of the maxilla 

 meetina; the forward extension of 

 the squamosal. The skull is shorter 

 and heavier, especially about the 

 rostrum, than somewhat younger 

 skulls from the Malay Peninsula. 

 The scales of the adult are large and 

 heavy, with the markings conspicu- 

 ous. Many of the scales are scarred 

 and broken.

 Cat. No. 142460, U.S.N.M. ; head 

 and body (to anus), 500 mm.; tail 

 (from anus), 510; greatest length of 

 skull, 104. .3 mm.; zygomatic width,

Skin and skull of an adidt female, 

 from the Kapuas River below Tyan. 

 In point of color and markings this 

 specimen is indistinguishable from 

 Tragulus kancMl of Sumatra, differ- 

 ing from that species only in the 

 greater length of the hind foot and 

 somewhat greater size of the skull. 

 In most respects, it resembles the 

 type of T. virgicollis (= T. hosei), 

 but differs from it conspicuously in 

 the absence of the narrow, well- 

 defined nape stripe. With but one 

 skin from the Kapuas River, it does 

 not seem advisable, for the present 

 at least, to recognize two distinct 

 races of the JcancJiil group onBorneo.
