96 BRITISH MAMMALS 



much less common in the east or south-east. It extends into 

 Scotland as far north as Aberdeenshire and Banff, and has been 

 found in the north, north-west, and south-east of Ireland. 



Daubenton's bat is sometimes confounded with the notch- 

 eared bat (Myotis emarginatus), a very doubtful British species, 

 which is described on p. 102. It may be distinguished at 

 once from the notch-eared bat by the absence of a very marked 

 indentation in the outline of the outer margin of the ear. The 

 feet in Daubenton's bat are larger proportionately than those of 

 Myotis emargmatus, and there is scarcely any trace in the former 

 of the two bats of that fringe of long hairs on the sides of the 

 upper lip and muzzle which is so marked a characteristic of the 

 whiskered and notch-eared bats. Daubenton's bat, no doubt, in 

 its wide range from Ireland to Burma, and from Finland to 

 North Africa, develops not a few local varieties which approximate 

 towards other distinct species. 



Myotis nattereri. THE REDDISH-GRAY BAT 



This bat is just under 2 in. in measurement from the tip 

 of the nose to the base of the tail, and the tail is a little over 

 i|- in. long. The ears are nearly three-quarters of an inch 

 in length, somewhat pointed at the extremity, but in general of 

 an oval shape. The inner margin is turned outwards, and does 

 not form any lobe by curving in the reverse direction towards the 

 middle of the ear. The outer margin nearly meets the inner at 

 the base, and its lower portion curls over towards the centre 

 of the ear. The tragus is narrow, sharply pointed, and curves 

 outwards. The eyes are very small. The nostrils are oval in 

 shape and surrounded by a naked patch above and below, which 

 is somewhat swollen. There is a thin moustache along the upper 

 lip, and a prominent sebaceous gland on each side of the face 

 above the lip. The head on the whole is rather small in size 

 proportionately. This appearance is, no doubt, the result of the 

 hair on the forehead and the nape of the neck being no longer 

 than that of the body. The interfemoral membrane which 

 connects the hind legs with the tail is supported by the calcaneum>
