 like the back, individual hairs 20 ram. long.

The black mask is very noticeable ; in a series of nine 

 specimens it is absent in only one, in which the face-hairs 

 are markedly longer, more coarsely annulate, and a red- 

 brown is substituted for the usual pale buff. 



In the general colour there is a strong likeness between 

 M, m. Lasti and M. melanurus of the West Coast, but the 

 black face suffices to distinguish the former. Even the excep- 

 tional individual mentioned above has a quite different look 

 to the minutely but distinctly grizzled mask of M. melanurus.
