Type localitii. — Hanau, Hessen-Nassau, Germany. 



Geographical distribution. — Central and southern Europe, 

 west to England, north to southern Sweden. 



Diagnosis. — Size slightly greater than that of M. nattereri 

 (forearm about 40, condylobasal length of skull, 16 to 17) ; ear 

 elongated, extending about 8 mm. beyond tip of muzzle when laid 

 forw^xrd, the conch broad (about 15 mm.), its posterior margin 

 obscurely emarginate above, the tragus scarcely half as high 

 as conch ; foot about half as long as tibia ; wing membrane 

 extending to base of outer toe. 



External characters. — In general like Myotis nattereri, but with 

 broader ears and relatively as well as actually larger legs and 

 feet (combined length of tibia and foot about 30 mm. instead of 

 less than 25). Muzzle with moderately developed glandular 

 swellings (these less evident than in M. mystacinus). Ear extend- 

 ing considerably beyond nostril when laid forward, its length thus 

 about as in M. nattereri, but its breadth so much greater (about 

 17 mm. instead of about 10 mm.) that the ear is relatively larger 

 than in any other European bat except Plecotus auritns ; form 

 of ear essentially as in M. mystacinus, the upper half of posterior 

 border faintly concave ; inner surface of conch wath about eight 

 rather ill-detined transverse ridges near posterior border ; anti- 

 tragus about 2 • 5 mm. in length along ba.se, rather abruptly
