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.
