Type species. — Vespertilio auritus Linnaeus. 



Geographical distribution. — Temperate Europe, Asia and 

 northern Africa. 



Characters. — Dental formula : i *=|, c Jd, pm ||, m || = 36. 

 Skull with large, elongate and rounded brain-case, and slender 

 but normally formed rostrum ; auditory bullse larger than in any 

 other European member of the family, their greatest diameter 

 equal to about three times the distance between them. Ears 

 very large, much longer than head, joined across forehead ; 

 nostrils opening upward, their orifices continued backward by 

 slit-like prolongations, the wart-like outgrowths on muzzle not 

 specially prominent. 



Remarks. — The genus Plecotus is at once recognizable among 

 European bats by the very large ears, joined across forehead. 

 In the only other European genus with 36 teeth (Miniopterus) 

 the ears are unusually short. Seven species are known, one of 

 which occurs in Europe.
