LXXIII. — On a Collection of Bats from Yola, Northern 

 Nigeria, collected by Mr. G. W. Webster. By Guy 

 DOLLMAN, B.A. 



The British Museum owes to the generosity of Mr. G. W. 

 Webster a collection of bats from Northern Nigeria, and, 

 being the first collection received from this region, it proves 

 of very great interest. In addition to some extremely rare 

 bats, it contains one new species, and there can be little 

 doubt that when the Nigerian fauna is thoroughly worked 

 out many other new forms will be discovered.
