This individual agrees very well with Dr. Anderson's description 

 and plate (quoted above), and I have no alternative but to place 

 it under his name. At the same time it should be noted that the 

 typical locality of P. yunnanensis is considerably to the north and 

 that another form of this same species, P. lylei mihi, is found 

 in Siam. It would therefore appear as if the present race was 

 in reality a Chinese form and that Annam and Yunnan form its 

 western limit. Except for the parachute the hairs of the whole 

 of the back in this individual are tipped with white, but not 

 sufficiently so as to conceal the chestnut ground-colour. 



P. lylei is much darker in general coloration than this species 

 and the anterior portion of the outer side of the ear is a bright 

 and pure chestnut. 



P. yunnanensis and P. lylei belong to a lai-ge group, of which 

 there are many geographical forms. Until, however, the group is 

 worlced out as a whole, it is best to retain them under binomial 

 names, but it should be borne in mind that they are merely 

 geographical forms of a large and widely distributed species.
