DAUBENTON'S BAT 



Genus Myotis 



DAUBENTON'S BAT 



Myotis Daubentoni, Leisler. 

 Plate 5. 



The distinguishing features of this species, by which it may be 



known at any time from Natterer's Bat, are the shorter ears and 



' tragus, large feet, the projection of the two last tail vertebrae beyond the 



interfemoral membrane, and the tiny lobe succeeded by a notch on each 



side of the latter near the tail. 



It differs from the Whiskered Bat, not only in the greater size of 

 the feet, but also in the attachment of the wing membrane, which starts 

 from the ankle and not from the base of the outer toe, as in the other. 



The expanse of wings in Daubenton's Bat is about 9 inches, 

 occasionally more. 



The ears are of medium size with rounded tips, and the tragus, 

 which is straight and pointed, measures about half their length. 



The glands are conspicuous on the muzzle, which is fringed with 

 hairs. The teeth number thirty-eight. In colour the upper parts are a 

 glossy umber brown, below pale brownish-grey. 



This Bat inhabits Europe and Asia from Scandinavia and Russia to 

 the Mediterranean countries, while eastwards it reaches Japan. 



Though known to Leisler and Kuhl on the Continent of Europe, 

 Daubenton's Bat was not fully identified as a British species till Bell 

 described it in the first edition of his British Quadrupeds in 1837.
