HAIRY-ARMED BAT. 29 



Temminck says that this Bat habitually retreats to the 

 holes of trees in the vicinity of stagnant water, a statement 

 the accuracy of which we are much disposed to question. 

 As it does not, according to him, occur in France or the 

 Low Countries, it is possible that he may not have himself 

 observed it in a state of nature. Two Swiss specimens 

 which we have examined are labelled thus : " Trouve 

 dans un vieux batiment dans le village Meyrengen au 

 printemps ;" which statement probably conveys a pretty 

 accurate idea of the resting-place of this species. 



The Hairy-armed Bat has been found in Germany and 

 in Switzerland, and we have seen specimens in the col- 

 lection of M, Verreaux of Paris, which had been re- 

 ceived by him from Sicily. Eversman includes it in 

 his list of species of the Ural Mountains, and Brandt, in 

 his work on Russian Mammals, mentions its occurrence 

 near the river Volga. We possess specimens from 

 Madeira, and have reason to suppose that it occurs also 

 with the Noctule in Algeria. 



The head is short and flattened ; the muzzle rather 

 elongated; the nose depressed and naked ; the nostrils 

 crescent-shaped ; a large sebaceous gland exists above 

 the commissure of the lips. Ears hairy on the inner 

 surface, oval-triangular, two-thirds the length of the 

 head, very broad ; the outer margin not reaching to the 

 corners of the mouth ; tragus half the length of the ear, 

 terminating in a rounded head, which is slightly curved 

 inwards, and produced on its outer margin. A band of 

 short hair, about four lines in breadth, extends along 

 the inferior surface of the fore-arm to the wrist, being 

 thickest and most extended about the latter part. Fur 

 long ; above deep brown at the base, bright chestnut at 

 the surface; beneath dusky at the base, dark greyish 

 brown at the surface. The two Swiss specimens to
