Reddish-grey Bat of Bell and others, but there are no local names. 



Distribution : — Natterer's Bat ranges through boreal and temperate 

 Europe and Asia from southern Sweden to Seville, Spain, and Arezzo, 

 Tuscany (specimens in British Museum), and from Ireland to Kiushiu, 

 Japan, where the representative sub-species is M. n. boinbitius of Thomas 

 {Proc. Zool. Soc. (London), 28th Nov., 1905, 337). It ascends to 2300 feet 

 in the Caucasus (Satunin). 



M. thysanodes of Miller {North American Fauna, 13, 1897, 80-85), 

 of the lower Sonoran zone from near the southern border of the 

 western United States to San Luis, Potosi and Michoacan, is probably 

 the representative in America. 



Thanks to Harting {Zoologist, 1889, 245-47), the distribution of M. 

 nattereri in the British Isles is now fairly well known. In England it is 

 found from Cornwall and the Isle of Wight to Durham in the north and 

 to Norfolk in the east. When Harting wrote there were fourteen 

 counties within the above area in which it had not been found. Five 

 only of these now remain, absolutely without records, viz., Wiltshire, 

 Hereford, Buckingham, Hertford, and Rutland. It has twice been 

 taken close to the Buckingham border (see Cocks ; also Steele Elliott, 

 Zoologist, 1903, 349), and our ignorance of it in this as in the other 

 counties is due almost certainly to want of observation. 



In Wales it probably occurs in every county, having been recorded 

 by William Thompson {Proc. Zool. Soc. (London), 13th June 1837, 

 52), from Harlech Castle, Merioneth, in the extreme west, a locality in 

 which J. Backhouse, jun., still finds it (Forrest, MSS., and Zoologist, 1898, 

 493, and specimen in British Museum) ; and in 1903 from St David's, 

 Pembroke (Forrest). In 1905 Coward and Oldham identified one while 

 flying in broad daylight near the Cefn cave, St Asaph, Denbigh ; in the
