This distinct species, the mainland representative of 

 C. Ogilbyi, is readily distinguishable from that animal by the 

 reversed hairs of the nape, the much broader dorsal streak, 

 which does not run on to the tail, the light-coloured feet, and 

 by the less swollen frontal region of its skull. 



It is still possible that C. Ogilbyi may occur on the main- 

 land, but these Fanti specimens are certainly not referable 

 to it. 



XXXVIII. — On Three new Races of Tragulus kanchil, 

 RaJ^es, with Remarks on the Genus. By J. Lewis 

 BONHOTE, M.A. 



A FEW months ago ]\Iessrs. Stone and Rehn published a paper 

 on some mammals from Sumatra*, and included in it a revision 

 of the genus Tragulus. 



With their findings as a whole I quite agree, and, having 

 Lad occasion lately to look up the genus, I find that we have 

 in the British Museum three apparently undescribed forms of 

 the smaller Chevrotain from Borneo, Bunguran Island, and 

 Cochin China, which I propose to describe. 



Before doing so, however, it may perhaps be as well to 

 make a few remarks on the whole genus. 



Many naturalists cavil greatly at the mass of names that 

 is slowly but surely rising round each group, which they 

 would call a single species, and thereby refuse to recognize 

 geographical forms. Now these races, which arise from their 

 geographical position, represent no doubt the initial differen- 

 tiations of new species, and, far from being ignored, should 

 be most closely studied. The easiest and simplest method of 

 doing so is to describe them and recognize them by means of 

 trinomials. 



I cannot agree with those who, while using trinomials for 

 continental races, refuse to allow them for insular races^ on
