308 VESPERTILIONIDJE. 



This species appears to connect the genera Vespertilio and Keri- 

 voula, agreeing with the species of the former genus in detention 

 and, slightly, in the form of the ears ; while the form of the head, 

 the semitransparent ears marked with glandular papillae, the great 

 length of the tail, the long calcanea curved backwards, and fringed 

 interfemoral membrane connect it closely with the species oiKerivoula.

Vespertilio bechsteinii, Leisler,KuM, Dewtsch. Flederm. Ann. Wetterau. 

 Gesellseh. Naturk. Bd. i. p. 30 (1819) ; Temm. Monoqr. Mammal, ii. 

 p. 184 (1835-41); Bell, Brit. Quadrup. p. 40, fig. (1837); Wagner, 

 Suppl. Schreh. Siiugeth. v. p. 723 (1855) ; Blasius, Fauna DeutscM. 

 p. 85, figs. 58, 69 (1857). 

 Ears narrow, much longer than the head ; outer margin of the 

 ear-conch very shghtly flattened beneath the tip, the remaining por- 

 tion as far as the base of the tragus convex, then slightly emarginate, 

 and terminating in a convex lobe : tragus long, attenuated, and 

 curved outwards above ; upper half of the inner margin convex, outer 

 margin correspondingly concave above (Plate XVIII. fig. 12, ear, en- 

 larged). 



Wings from the base of the toes ; the last rudimentary caudal 

 vertebra free. 



Fur, above and beneath, dark brown at the base ; the extremities 

 of the hairs above light reddish, beneath white. Distribution of the 

 fur as in V. murinus. 



Length (of an adult specimen), head and body 2", tail 1""5, head 

 0"-75, ear 0"'95, tragus G"-48, forearm l"-55, second finger 2"-7, 

 fourth finger 2"'l, tibia 0"'8, foot and claws 0"'35. 



Hah. Europe (from Southern England to Southern Eussia, and 

 from Sweden to the Alps). 



V. bechsteinii resembles F". murinus in general form, but is readily 

 distinguished from that species by the proportionally much longer 

 ears, by the very different form of the tragus, by the wing-membrane 

 extending quite to the base of the toes, and also by its considerably 

 smaller size.
