 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 ciliated. 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 greyish-brown above, ash-coloured below. Length 

 If inches. Breadth 7 inches.

Devonshire, Montagu — At Dartford in Kent, Mr Peel. 

 In this species, the forehead is bald, the fiir dark brown, becoming mixed 

 with silvery hairs with age. Length 4 inches ; breadth 1 1 inches. Weight 

 100 grains. Ears notched and waved on the margin. Montagu states, that 

 " the teeth are numerous in both jaws, and much jagged ; 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.

 ly placed. Summits of the grinders with conical points.
