N0.1317. MAMMALS OF NORTHWEST SUMATRA— MILLER. 445 



by orange-ochraceous except a veiy narrow line along- under surface 

 of tail, and two faint traces 20 mm. in length on middle of chest. In 

 the majorit}^ of specimens the under parts are as in th(> type, except 

 that the white areas are slightly more extended and the throat mark- 

 ings are normal in extent and pattern. The dark throat stripes, 

 however, are never as dark as those of T. kanchil or as those of th<J 

 specimen described as T. f\dvlventer hy Stone and Rehn. 



Shdl and teeth. — Except that they are larger throughout, the skull 

 and teeth are essentially as in the Tragulus fuhnventer of Stone and 

 Rehn.

 35 (32); mandibular toothrow (alveoli), 41 (37). 



Specimens examined. — Fifteen, all from Pulo Tuangku. 



RemarJtS. — This species is readily distinguishable from Tragidus 

 Tcanchil by its smaller size, brighter, more fulvous color, the greater 

 extension of the fulvous wash on belly and chest, and the character of 

 the throat markings. It is evidently more closely related to Tragidus 

 fulm/ventefr. With this animal it agrees in size and in the general type 

 of coloration, but differs in the very light color of the brown throat 

 markings and the tendency of the white stripes to become obsolete, in 

 the latter peculiarity showing an interesting parallelism with Tragidus 

 jugular /s of Pulo Mansalar. Of Tragulus fulviventer I. have examined 

 the specimen described by Stone and Rehn, and Mr. Oldfield Thomas 

 has sent the following measurements of Gray's type, an adult female 

 in the British Museum: Head and body (skin), 450; hind foot with 

 hoof, 122; basal length of skull, 84; palatal length, 59; interorbital 

 breadth, 24.5; combined length of three upper premolars, 18.5; com- 

 bined length of three lower premolars, 18.5. 



'^ Measurements in parentheses are those of the specimen Tragulus fulviventer of 

 Stone and Rehn, male adult, No. 642, Philadelphia Academy of Sciences.
