Species o/VespertilionidEe. 261 



beneath, the basal half of the hairs is dark, the terminal half 

 white. 



Length (of an adult male preserved in alcohol) — head and 

 body 2*5 inches, tail 2*3, head 0'9, ear 0'85, tragus 0*4 x - l, 

 forearm 2*2, thumb 0*45, second finger 3*7, fourth finger 3, 

 tibia 1*05, foot and claws 0*45. 



Hab. Gaboon, W. Africa. 



This species belongs to the same section of Vespertilio as 

 V. murinus of Europe, which it very closely resembles in 

 general form, in size, and even in the colour of the fur. It 

 is, however, at once distinguished by the much shorter ears, 

 acutely pointed tragus, and great development of the glands 

 of the muzzle. The wing-membrane also does not extend so 

 far outwards along the foot as in V. murinus, and the inner 

 side of the ear-conch is less hairy. 



Though thus readily distinguished from V. murinus of 

 Europe, I am induced, on account of its very close general 

 affinities to that species, to consider it a subspecies only. 



Type in the collection of the British Museum. 



b. Feet very large; wings to the ankles or tarsus. (Subg. Leuconoe.) 

 Vespertilio megalopus, n. sp. 



Very similar to V. Daubentonii ; but the ears are longer, 

 much narrower and more acute, and, laid forwards, the tips 

 pass beyond the end of the nose at least one tenth of an inch ; 

 the inner margin, instead of forming a regular arc from the 

 base to the tip, is flattened along the upper third, and the 

 narrow extremity of the ear is sharply rounded off. The 

 tragus is also longer and narrower, and the upper third of the 

 inner margin is slightly concave ; but the extremity is not 

 directed inwards. 



The wing-membrane does not extend so far down on the 

 tarsus as in V. Daubentonii ; and the second upper premolar is 

 slightly drawn inwards. In other respects, in general form 

 and in the colour and distribution of the fur, this species closely 

 resembles V. Daubentonii, of which it may be considered the 

 African representative. 



Length (of a male specimen preserved in alcohol) — head and 

 body 1 '65 inch, tail 1'6, head 0*6, ear 0'55, tragus 0*3, fore- 

 arm 1'45, thumb 0*35, second finger 2'3, fourth finger 1*9, 

 tibia 06, foot and claws 0'4.
