310 VESPERTILIOKIDJE. 



structure except the dentition. The outer incisors equal to the 

 inner in cross section at the base, but much shorter. Lower in- 

 cisors in a semicircle scarcely overlapping each other. In this bat, 

 as in the noctule, a band of fine short hair passes on the underside 

 behind the forearm to the carpus, hence the English name. 



Colour of fur bright yellowish brown above, light brown below, 

 the basal three fourths of the hairs on both surfaces dark brown. 



Dimensions, Head and body 2'4 inches, tail 1*6, ear from crown 

 0-25, forearm 1-65. 



Distribution. Europe and the temperate regions of Asia. There 

 are in the British Museum specimens collected by Button at 

 Mussoorie, whence also the species was recorded by Blyth. It 

 does not appear to have been observed elsewhere in the Himalayas. 



Habits imperfectly known, Blasius saying that this species is a 

 high-flyer and tree-haunter like V. noctula ; whilst Bell in his 

 ' British Quadrupeds ' doubts its dwelling in trees, and states that 

 its flight is much less steady and powerful than that of the noctule. 

 It appears early in the evening. 



There is in the British Museum a skin of V. imbricatus, marked 

 Calcutta, and sent by Blyth to the East India Company's Museum. 

 As the species is not mentioned by Blyth, and no specimens 

 collected by him are in the collection at Calcutta, it is doubtful 

 if the specimen above noticed is Indian. The species, which is 

 found in the Malay Peninsula and Java, may be recognized by its 

 comparatively large well-rounded ears, and its crescentic pointed 

 tragus. The forearm measures 1 *4.
