with hair as far as the end of the third caudal vertebra ; above, the 

 wing-membrane is covered as far as a line drawn from the knee to 

 the middle of the humerus. 



Teeth as in F. noctula ; the small first upper premolar often 

 absent. 



Hab. Japan ; China. 



There can be little doubt that the excellent full-sized figures in 

 Schreber's work, referred to above, were taken from this variety of 

 the Noctule. They correspond in all respects in measurements, and 

 could never have been hitended to represent the common form of 

 V. noctula, which, indeed, is drawn of the natural size in plate Hi.

 of V. leisleri, see Table, p. 216.)

Very similar to V. noctula, appearing on a superficial examination 

 to be but a small form of that species. It is, however, easUy dis- 

 tinguished by the colour of the fur and by the relative size of the 

 inner and outer upper incisors. 



In V. noctula the fur is unicoloured above and beneath, or the 

 colour of the hairs is slightly paler towards their bases, while in this 

 species the terminal one fourth of the hairs above is bright yellowish 

 brown, beneath light brown, the basal three fourths of the fur on 

 both surfaces dark brown. The outer incisor, also, in this species is 

 equal to the inner incisor in cross section at its base, but in V. noc- 

 tula it is double the size of the same tooth at its base. The lower 

 incisors stand in the direction of the jaws, in V. noctula they are 

 crowded and parallel. 



Hab. Europe and the temperate regions of Asia, probably gene- 

 rally distributed throughout the warmer parts of the Palaearctic 

 Region. Recorded from Ireland, England, France, Germany, 

 Middle Russia, and the Ural, extending also from Madeira and 

 the Azores through the Alps and other mountain-ranges to the 

 Himalayas.
