Allied to and apparently about the size of T. napu^ F. Cuv. 

 ArraiigeniCDt of colours above much as in that species, but 

 the whole of the dorsal and lateral siu'faces broadly washed 

 ■with jet-bhiek, the hairs wiiite at their bases, then dull orange 

 and broadly tipped with black. Nape with the indistinct 

 blackish line found in T. napu. Face and sides of neck 

 mixed black and dull fulvous. Chin with the usual naked 

 glandular ])atch between the rami of the lower jaw. Arrange- 

 ment of white throat-bands quite different from that of tlie 

 allied species, jierhaps most similar to that of T. Skinleijanus. 

 All the stiipcs very narrow, sharply defined. Anteriorly on 

 each side of the naked space there is a short pure white stripe, 

 which ends abru})tly at about the level of the posterior canthus 

 of the eye ; these short stripes are completely separated from 

 each other and from the posterior stripes by a dark brown 

 space, the break in their continuity with the latter being not 

 less than one inch in length. Posteriorly the median white 

 stripe, which is very narrow and scarcely broader behind, is 

 bounded on each side^ between the lateral white stripes, by 

 deep jet-black fur, strikingly different from the fur in the 

 corresponding position in the other species. Behind the 

 stripes are separated from the white j)atch between the fore 

 limbs by a broatl blackish band. Belly-hairs broadly tij)ped 

 ■with black, but the inner sides of the thighs, as usual, wiiite.

it is untbrtunate that the only specimen obtained of this 

 new Chevrotain is both young and in bad condition; but its 

 general blackness and the peculiar character oi its throat- 

 markings separate it at once from any of its congeners.
