DR. J. E. GRAY ON THE PTEROPINE BATS. [Jan. 23, 



of this species, if that were possible, would have the colours also more 

 intensified, instead of less so. 



I have great pleasure in naming it after Mr. Wallace, who has en- 

 riched our Museum with so many new and beautiful species. It is 

 most like Pteropus personatus, but very distinct, and about one- 

 third less in size. 



The only other species that has the face ornamented is P. perso- 

 natus ; but that has only brown lines on the side of the face and 

 round the eyes. It, like this, is a small species in the genus. 



As P. personatus lias not yet been figured, I have given figures 

 of the heads of the two species for comparison.

Deep black ; the under surface and the rump with interspersed 

 white hairs, most abundant on the latter part ; a small round tuft 

 of bright yellow hair on the upper part of each shoulder. 



Hab. Island of Johanna, Comoro group (Dr. Livingstone).
