moderatelj^ developed, not causing a depression on the face above ; 

 end of nose and upper lip slightly projecting beyond the lower 

 lip; inner basal lobe of ear-conch rounded, not very convex for- 

 wards ; inner margin of ear regularly convex to the tip ; rather 

 more than the upper third of the outer margin is straight or slightly 

 concave, a narrow portion of the edge about the middle is folded 

 backwards, then emarginate opposite the base of the tragus, and 

 terminating in a long and deep, but not prominent lobe behind the 

 angle of the mouth, from which it is separated by a wart ; tragus 

 narrow opposite the base of the inner margin, expanded above, the 

 outer margin attaining its greatest convexity slightly above the 

 middle of the inner margin, which is straight or slightly convex 

 above, at the base of the outer margin a triangular lobule. 



Wings from the base of the toes, which are three fourths the 

 length of the whole foot. Calcaneum margined posteriorly by a 

 narrow lobe. The last caudal vertebra and p^t of the antepenulti- 

 mate vertebra free. 



On the upper surface the fur of the body extends upon the wing- 

 membrane almost as far as a line drawn from the middle of the 

 humerus to the knee-joint, on the interfemoral membrane as far 

 as the end of the fourth caudal vertebra. Beneath, the wing-mem- 

 brane is similarly covered ; but almost the whole interfemoral mem- 

 brane is covered with fine hairs, which abound principally along 

 the tan. 



Fur, above, dark broMm, the terminal fourth of the hairs shining 

 yellowish white ; beneath, dark brown, the terminal fourth of the 

 hairs ashy. 



Upper inner incisors long, bifid, the outer cusp shorter than the 

 inner, and placed slightly posterior ; the outer incisors unicuspi- 

 date and short, not equalling the outer cusp of the inner incisor in 

 vertical extent. Lower incisors slightly crowded, but not overlap- 

 ping. First lower premolar about half the height of the second. 



Length, head and body l"-95, tail l"-7, ear 0"-6, tragus 0"-25, 

 forearm l"-6, thumb 0"-28, third finger 2"-5, fifth finger 2", tibia

Hah. The Palajarctic Region. In Europe extending from England
