BY GERRIT S. MILLER, JR.

 F. Cuvier and as represented by a specimen from Linga Island,

 may be known as: 



Trajulus canescens sp. nov.

 tional Museum. Collected in Trong, Lower Siam, September 7, 189(5 by 

 Dr. W. L. Abbott, 



Chonn-terN. Larger than Tragulus napu and much paler, less yellow

 faintly shaded with gray along median line; sides clear gray: dark nape 

 band obsolete.

 ish tips of the hairs a clear gray, faintly yellowish, strongly contrasted 

 with color of back. Flanks more tinged with buff than sides. Harsh 

 fur of shoulders, neck and nape irregularly and coarsely grizzled with
