 Mr. Gerrit S. Miller, Jr., curator of mammals, for the loan of 77 specimens 

 of African Molossidse and Vespertilionidse. Although very few of the 30 

 species represented in these loans were contained in the Lang and Chapin 

 collection, they were nevertheless of much assistance in working out the 

 species in the latter. It was therefore necessary to proceed with the work 

 almost exclusively from the basis of the literature. 



Andersen's work on the Megachiroptera 1 has rendered comparatively 

 easy the determination of the specimens of this suborder; Miller's 'The 

 Families and Genera of Bats ' 2 has been invaluable as a general guide to the 

 minor groups. Aside from a few papers reviewing special groups of species, 

 the literature is widely scattered, the latest general revision being Dobson's 

 ' Catalogue of Chiroptera,' 3 published nearly thirty years ago. 



The bat fauna of the Belgian Congo is apparently poorly represented in 

 museums, judging from the infrequency of references to specimens from 

 this region in literature. 4 A considerable number of species, however, 

 have been described from bordering districts which should naturally be 

 expected to occur in Belgian Congo, but they are for the most part un-
