described; for die darker hue in the latter case is due to the 
longer and harsher hairs of the fur, which hairs being almost 
entirely wanting in M. gracilis, the softer grey under fur is 
exposed. An immature specimen of M. Dama , sent with 
the male and female from which my descriptions are taken, 
and forming part of the British Museum collection, furnished 
the dimensions given in the third column. The structure of 
the incisor teeth is the same in M. gracilis and M. Dama; 
and it will bo seen by the dimensions just referred to, that 
(making a slight allowance for measurements taken from 
skins) the proportions are the same.
