 and third metacarpals are longer, but the longest digit is shorter. 

 Daubenton's Bat, on the other hand, is distinctly larger than the 

 Whiskered, and, apart from its shorter, hardly-notched ear, and 

 shorter tragus, broadest at about its centre, is easily marked out by 

 the proportions of its large foot and calcar. 



DIMENSIONS IN MILLIMETRES: 



The Whiskered Bat is probably the commonest British 

 representative of its genus. It was described by the German 

 naturalist Leisler early in last century, and was first recorded 

 as British by J. E. Gray^ in 1826. Gray supposed that 

 Montagu confused it with the Barbastelle, and stated that 

 the specimen thus named in the British Museum, which 

 belonged to Montagu, was really a Whiskered Bat. The bat 

 was afterwards obtained by Jenyns, Yarrell, and Bell, the latter 

 of whom figured it in his first edition. In Ireland, J. R. 

 Kinahan found it in County Clare in 1853, and it has since 

 been shown to be anything but rare. In fact, in the 

 west of England and Wales it probably outnumbers the
