Fur. — Rough below like mohair, lying natter and smoother on

Wing. — Humerus and radius very muscular, phalanges of fingers 

 similar to those of other bats, but index ended by a small hooked 

 nail bending upwards, or outwards from the plane of wing. Wing 

 near arm clothed with scanty woolly fur. And from radius to edge 

 of the membrane extend interrupted parallel muscular strips, fifteen 

 in number : these are crossed here and there by veins, and one very 

 large strip runs along interfemoral membrane, up its centre. Carti- 

 laginous appendage from near root of inner toe running through 

 (across) interfemoral membrane, weak and small. No vestige of tail. 

 The wing membrane attaches to the root of the index finger of the 

 hind paw, spreading across front of foot or instep. 



Paws. — As in all bats — claws subequal. 



Genitals. — Male. Testes large, oval, placed on each side of 

 penis. Penis pendant, with flat denuded glans, having a lateral
