444 Zoological Society : — 



The fur is everywhere thick and cottony, and is either bicoloured 

 or tricoloured, with a tendency to spread on to the upper surface of 

 the interfemoral membrane. 



At present I have not had the opportunity of examining the cra- 

 nium of either of the species, but am able to observe in the sj)eci- 

 raens in spirit and in those in skin, that the front teeth are of con- 

 siderable substance in relation to their length, and that the upper 

 incisors are placed in pairs, the pairs being separated from the canines 

 by a considerable interval on each side, and from each other by a 

 central interspace. 



From the Kerivoula picta, and a few more allied species, this 

 group differs remarkably in not having the top of the head elevated, 

 in ha^dng the muzzle much thicker relatively, in the greatly inferior 

 development of the ear-conch, and in several other minor details. 

 However, it agrees with Kerivoula in the form of the tragus, and in 

 some measure in the texture of the fur.

Although the present well-marked species is cancelled froxn the 

 European list by MM. Keyserling and Blasius, it is certainly a per- 

 fectly distinct and easily recognizable species, and not uncommon in 

 several localities on the continent of Europe ; but does not I believe 

 occur in the British Islands. I have seen and examined specimens 

 in the Museums of Leyden and Paris ; in the latter, the type spe- 

 cimens from Charlemont and Abbeville, together with others col- 

 lected by jNI. de Selys-Longchamps in Belgium ; but I sought in 

 vain for the specimen which M. Brongniart obtained near Dover. 

 I believe that it was merely an old female of V. jni/stacimis ; and per- 

 haps from its cranium the illustration was taken which accompanies 

 the description given by M. Geoffroy. At any rate that figure re- 

 presents with tolerable accuracy the cranium of V. mystacinns, and 

 is obviously too small for the V. emarginatus, as well as being too 



very much on the elongation of the phalange next to the one bearing the claw ; 

 and it is the corresponding phalange of the thumb that is so much the longest. 

 It would appear worthy of inquiry whether the corresponding phalanges of the 

 fingers are relatively longer. This I do not find to be absolutely the case, although 

 in Miniopteris reversed proportions of the comparative length of the toes with 

 the remaining part of the foot take place, accompanied by corresponding reversed 

 proportions in the length of the phalanges of the fingers. Thus the toes are 

 short, and the phalanges of the fingers which answer to them, equally short ; in 

 the present group the toes are long, and the joint of the thumb which corresponds, 

 elongated in accordance with them ; but the wing-joints exhibit no such relative 

 proportions.
