CHIEOPTERA 



above a light drab tinged with grey or with ecru-drab, the 

 general effect paler and more greyish than in any of the other 

 European species ; underparts pale buffy grey, rather strongly 

 contrasted and with moderately well-defined line of demarcation 

 along sides of neck. Underfur slaty black. Muzzle and 

 cheeks faintly dusky. Ears and membranes an indefinite rather 

 light brown. 



Skull. — In all respects the skull so closely resembles that of 

 Myotis daubentonii that it is only distinguishable by its larger 

 size. Erom the skulls of M. nattereri and M. emarginatus it 

 differs in its greater breadth, a character perhaps most readily 

 appreciable in the form of the post-palatal region. 



Teeth. — Except for their larger size the teeth resemble those 

 of Myotis daubentonii. The crown area of upper molars is 

 relatively less than in M. nattereri and M. emarginatus, though 

 m 3 retains the broader outline characteristic of M. daubentonii 

 and M. mystacinus. Upper molars with protoconule and its 

 accessory small commissure, and m 1 and m 2 with commissure 

 between hypocone and metacone as in M. daubentonii. 



Measurements. — Average and extremes of forearms in four 

 males and eight females from Lugano, Ticino, Switzerland : 

 males, 39-9 (38-8-41); females, 39-4 (38-8-40-4). Sicily 

 (type): tibia, 15- 6; foot, 12; forearm, 39-2; thumb, 10 ; third 

 finger, 56 ■ 2 ; fifth finger, 50. Adult male from Oorleone, Sicily : 

 head and body, 49 ; tail, 38 ; tibia, 16 ; foot, 10 ; forearm, 41 ; 

 thumb, 8 • 2 ; third finger, 68 ; fifth finger, 55 : ear from meatus, 

 1 5 ; width of ear, 10-4. Two adult males from Sassari, Sardinia : 

 head and body, 50 and 51 ; tail, 37 and 37 ; tibia, 16 -4 and 17 ; 

 foot, 10-6 and 11 ; forearm, 39-4 and 41-6 ; thumb, 8-4 and 

 8-6 ; third finger, 66 and 69 ; fifth finger, 51 and 56 ; ear from 

 meatus, — and 14*4; width of ear, 10 and 10. For cranial 

 measurements see Table, p. 191. 



Specimens examined. — Seventy-two, from the following localities : — 



Austria-Hungary : Herkulesbad, 1. 



Switzerland : Near Lugano, 49 (B.M., U.S.N. M., and Mottaz).

Hemarlts. — In general appearance this species resembles 

 Myotis daubentonii ; but it is immediately recognizable by its 

 even larger foot, and by the densely pubescent upper surface of 

 leg, the latter character unique among European bats.
