tliat inhabiting Chili and the Argentine, to which therefore 

 a special subspecific name might be given. 

 I would propose to call it 



Grison furax melinus, subsp. n.

 exchange an example of Glironia from Yungas, Bolivia, 

 which had been in the Hamburg Museum for some years, 

 having been purchased from Rolle in 1897. 



The specimen is an immature male in spirit, and by its

 account of Glironia f and to add some further information 

 about it.

 than appeared on the skin and that the middle line of the 

 underside, instead of being naked only for its terminal three
