bat Tho flpecies may be confounded with both V. Nattereri and V. 

 mystacinu8, agreeing with both in the fiinge to the interfemoral, although 

 this character has been pointed out as distinctive ; it differs from both, 

 however, in the arrangement of the lines on this membrane ; in the 

 reddish- gray bat, these are few in number, and very strongly marked ; 

 in the whiskered bat they are numerous and distinctly marked, whilst 

 in Daubenton's bat they are numerous, but confused, running into one 

 another. 



The colour of the for separates it from F. mystacinusj being de- 

 cidedly of a reddish-brown tinge on the back in Daubenton's bat, and 

 in the other dark, almost black ; Natterer's bat is much lighter than 

 V. Daubentanit. It has been seen that it agrees with the whiskered 

 bat in bearing a moustache, but this in the whiskered bat is much more 

 prominent cmd better marked. From its great abundance in Kildare, 

 from whence my friend, F. Haughton, Esq. , has since forwarded speci- 

 mens, I think it likely it has been often overlooked elsewhere in Ire- 

 land. 



Specimens are in the National Museum, and in the Natural History 

 Society's Collection.

Professor M'Coy gives the following description of the above, tho 

 only as yet recorded Irish specimen : — 



" Spur or heel unusually long, extending nearly half-way between 

 the hind-foot and extremity of the tail ; edge of interfemoral from ex- 

 tremity of spur to the tail, crenulated and frmged with short, stiff hairs; 

 oblique glandular bands of the interfemoral membrane do not exceed 

 eighty head small ; ears nearly equalling head in length, ovate ; ^vidth

The above 8i)eciraen was until lately in the collection of the Natu-

 capture incorrectly as EnniskciTy, county of Wicklow.
