DAUBENTON'S BAT. 65 



parts of Germany, is common at Hanau, in Wetteravia, 

 and was taken by Dr. Natterer in Vienna. According 

 to M. Temminck, it occurs in Sardinia, but not in the 

 north of Europe, a statement which is certainly incor- 

 rect, as in the first edition of this work it was shown, on 

 the authority of Dr. Beck, to be a Danish species, and 

 we find it included by M. Nilsson in his Scandinavian 

 Fauna, as well as by Prof. Brandt in his work on the 

 Russian Mammals. Dr. Eversman has described a 

 variety of this Bat under the name of Vespertilio Volgensis, 

 which he met with on the slopes of the Ural Mountains, 

 and near the river Volga. Finally, we add Japan to the 

 enumeration of localities from which examples of Vesper- 

 tilio Dauhentonii have been received, as an examination 

 of Japanese specimens in the Leyden Museum has satis- 

 fied us not merely that the Noctule occurs there, as stated 

 by M. Temminck, but that the Vespertilio macrodactylus 

 of that distinguished zoologist is referable to the species 

 we have now under review. 



The head is rather small ; the forehead somewhat ele- 

 vated, and the top of the head a little flattened ; the 

 muzzle obtuse, with numerous long and stiffish hairs, and 

 a moustache of soft long hair on each side of the upper 

 lip, which is also tumid from a congeries of sebaceous 

 glands on each side. Ears of moderate size, about three- 

 fourths the length of the head, oval, bending a little 

 outwards ; the external margin very slightly notched, the 

 inner margin with a fold near the base. Tragus some- 

 what lanceolate, narrow, sub-acute at the apex, turned 

 a little inwards, half as long as the ear. Tail a little 

 longer than the fore- arm, exserted at the extremity for 

 about a line. Hinder extremities robust ; the feet strong, 

 and the outer toe very distinct from the rest. Wing 

 membranes extending only to the distal extremity of
