Plecotus. MAMMALIA. CHEIROPTERA. 7 



Gen. III. PLECOTUS. Ears approximating, and united at 

 their inner edges above the eyes. Auricles semicordate. 



6. P. auritus. Eared Bat. — Ears nearly the length of the 



body, blunt. 



Penn. Brit. Zool. i. 147. tab. xiii. f. 40— Flem. Phil. Zool. tab. i. f. 1.— 

 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 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 

 1 1 inches. Breadth 7 inches. 



7. P. Barbastellus. — Ears about the length of the head, 

 broad.

 Devonshire, Montagu At Dartford in Kent, Mr Peel. 



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

 with silvery hairs with age. Length 4 inches; breadth 11 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. 



II. FERA. 



PLANTIGRADA. 



I. The second incisor on each side in the lower jaw uniform- 

 ly placed. Summits of the grinders with conical points. 

 Clavicles developed. 



A. Middle incisors produced, without intermediate small 

 ones, the lateral ones and tuslcs short. 



Gen. IV. ERINACEUS. Urchin or Hedge-Hog— Two 

 middle incisors above, cylindrical.

This species, widely distributed throughout Europe, is the Dreanog of the 

 Welsh, and the Graineag of the Gael ". The ears are short, the snout pro- 



* In giving the provincial names, E, is placed for English ; S, for Scottish;
