Not uncommon in England and Scotland. 
In this species, the forehead is covered with hair. The ears, which are de- 
pressed when the animal is at rest, have transverse ridges towards the outer 
edge ; and the ridge towards the internal edge is cUiated. The tail extends 
a short way beyond the membrane. The nostrils have a recess. The inci- 
sors above are 4, in pairs, remote, the two middle ones notched, and the two 
lateral ones subulated. Fur greyishdirown above, ash-coloured below. Length 
If inches. Breadth 7 inches.

In this species, the forehead is bald, the fur dark brown, becoming mixed 
with silvery hairs with age. Length 4 inches; breadth fl inches. Weight 
100 grains. Ears notched and waved on the margin. Montagu states, that 
“ the teeth are numerous in both jaws, and much ja^ed ; in the upper, four 
cutting teeth, but no canine, and a vacant space between these and the grind- 
ers: in the lower jaw six cutting teeth, and four canine or longer teeth, and 
between these last on each side is a small intermediate one : these longer 
teeth fall into the vacant space in the upper jaw.” In examining the teeth 
of bats, however, we should bear in mind, that some of these drop out at an 
early age, and that others, especially the incisors and foremost grinders, are 
frequently minute, and easily overlooked.
