NO. 1317. MAMMALS OF NORTHWEST SUMATRA— MILLER. 441 



the .strono- contrast between the superciliaiy stripes and the black, 

 very obscurel}' grizzled crown. Inner surface of legs, under surface 

 of tail, and entire ventral surface behind throat markintrs orano-e 

 buti'. ])riohter on legs and middle of chest, duller on tail, and paler 

 and more gray in axillary and hypogastric regions; middle of belly 

 with a distinct dusky wash. The portion of chin normally white is 

 conct)lor with cheeks, and the light throat stripes are merely indi- 

 cated by a stronger grizzle of tawny ochraceous in the general black 

 of the throat. This indication, however, is so distinct that it can not 

 be overlooked, and in many specimens it is even more evident than in 

 the type. In none of the 17 examined is it absent. The pattern thus 

 outlined is in every respect normal. Collar of normal extent, but 

 rather morc^ tawny than in Tragulus arii(Vinn<. Ears, naked area 

 around and in front of eyes, feet, and lower half of tarsus and carpus 

 covered with minute blackish hairs. 



The series is very uniform in color. Some variation is shown in 

 the distinctness with which the throat markings are indicated, and in 

 the amount of dusky wash on the belly. In many skins the blackish 

 hairs on feet and distal portion of legs are mostly replaced ])y tawny, 

 but in general the dusky feet are characteristic. None shows distinct 

 white on any part of the body. 



Shill and teeth. — While the skull is smaller than that of Traguhm 

 najju, I can see nothing to distinguish it from that of T. amcenus^ 

 with which it agrees in both size and form. The teeth, on the other 

 hand, particularly the premolars, are distinctly larger than in the 

 related species.
