144 MAMMALS 



Although I visited Ngamba every week between March 

 and August 1914, I did not find these bats congregated 

 after April. 



Since the expanse of wings is about two feet, they look 

 large creatures in flight, and the beating of the wings 

 makes a considerable noise when one disturbs a large 

 congregation. 



At night the " Ekinyira " in the forest keeps up a most 

 insistent loud noise at intervals of about a second. For a 

 long while I thought it was produced by a large frog. 

 It is a sharp note, between a high-pitched croak and a 

 grunt, with something of a bark in it. It may be heard 

 from shortly after sunset for hours on end, and, if one 

 awakes in the middle of the night, may still be heard 

 coming from the same spot !
