I'uces, ranging from Sumatra to Ohii)a and tlie Himalayas. He declines 

 to recognise them as different species and remarks, " I have a strong' 

 '' snspiinou that when the Serows are b-.:5tter known, that is to say 

 " when more n>aterial has been collected, gradations will be traced and 

 •■' tluTs justify tiie view I now hold that all the Serows ranging from 

 " Kashmir to Burma belong to one locally variable spedes. But, " he 

 continues, " I am not sure that future discoveries will not show that 

 " the Serows of the Straits Settlem-^nts should rank together with the 

 '" Sumitran animal, as specifically distinct. '' 



I propose, in this article, to confine m^yself to those races of 

 Serows which have been ali'eady described from this region, that is to- 

 say from the countries adjacent to Sian>. and to show afterwards how 

 they differ from the ones I have met with myself. 



It may be as well to remark at this point that Mr. Pocock has 

 re-introduced the generic tille ot CUpricornis for the Serows in the 

 place o^ Nemorhaedics, which has been used by Blanford, Lydekker and 

 other authorities for u^an}' years, and gives his reasons for so doing on 

 the grounds of ]>riority It remains to ba seeti whether or not his 

 new term will be finally acce])ted. 



In the following descriptions I have not hesitated to quote freely 

 from all the authoi-ities at my dis|><^al. The last variety to be des- 

 cribed, although stated to be found in countries far removed from Siam, 

 hxs been included here as, in colouration, it ap[)roximate« veiy closely tcv 

 specimens that have been found in this cour.trv.
