Going by external characters and using the key given by 

 Pocock (P. Z. S. 1908, p. 190) for identifying his seven geogra- 

 phical races of C. sumatraensis, we find, however, that the Serow 

 from Annam differs markedly from the subspecies rodoni, the latter 

 having " breast and underside white, and sharply defined from the 

 dark colour of the rest of the body," and that it comes nearest to 

 the sub-species jamraclii, from Darjiling, though differing from it 

 by its forehead being rufous, instead of coal black, by its coat being 

 shaggy, instead of ' short at all seasons,' and other characters.
