the point becomes worn or the inner incisor grows longer, and it is 

 then slightly or considerably shorter. The length of this incisor, 

 however, is variable within a short compass ; and I have found it in 

 the same individual shorter than the outer cusp of the inner incisor 

 on one side of the mouth, and longer than it on the other. Lower 

 incisors very slightly crowded, in the direction of the jaws. The 

 second upper premolar is separated by a small space from the canine, 

 and through this interval the summit of the small internal first 

 premolar is visible, which is larger than in V. ahramus.

Hah. The Palaearctic Eegion, apparently generally distributed. 



V. lacteus, Temminck, which I have identified with this species, 

 was founded on two specimens from an unknown locality, which 

 the describer thought was probably South America, as they were 

 discovered in a collection made in that region. These specimens, 

 which are preserved in the collection of the Leyden Museum, agree 

 in all respects in structure and in the colour of the fur with speci- 

 mens of V. pipistrellus from the sandy deserts of Eastern Turkestan ; 

 and it is probable that this species has always very pale-coloured 

 fur when inhabiting dry sandy districts, as has been observed under 

 similar conditions in other species of Bats, as in V. Icuhlii and V. 

 serotinus. The same remarks apply to Kerivoula grisea. Gray (also 

 from unknowTi locality), which I cannot distinguish from this 

 species.
