Vespertilio Madagascariensis, n, s. 



The species which I have thus named, although not appertaining 

 to the restricted group which forms the subject of the present paper, 

 is nevertheless a true f'espertilio. It is properly a member of the 

 restricted group which is represented by F. mystacimis, V. j)oly- 

 thrix, V. Chilooisis, V. ruber, J'. Isidori, V. Hilairii, V. parvulus, 

 V. triUititius (Tenim. not Ilorsf.), and some others. As the first 

 of these is the best-known species, I shall take it as a standard for 

 comparison, and at the same time refer to any points of greater re- 

 semblance which the new species may have to others less known. 



It is of about the same size as V. Bauhentonii, but differs from 

 it in other respects considerably. The top of the head is somewhat 

 elevated, as in V. niystacinus, and, as in that species, the muzzle is 

 rather short and pointed. The nostrils are small, near together, 

 sublateral in their direction, and the space between them emarginate. 

 The ears are of medium length, rather broadly ovoid, and deeply 

 emarginate about the middle of the outer margin ; but the notch has 

 not the aj>pearance of being scooped out, as in the species previously 

 described in the present paper. It is in fact just as in V. niystacinus, 

 but deeper. The tragus is about half the length of the ear, narrow 

 and pointed, and curving slightly outwards. It has a prominent 

 angle on its outer margin near to the base. 



The thumb is small, and the two visiljle phalanges are of nearly 

 equal length. The wings are proportioned much as in V. jnysta- 

 cinus. The feet are relatively rather large as compared with those of 

 that species, but much less so than in T'. Danlientonii, and the wing- 

 membranes extend nearly to the base of the toes, the latter being of 

 nearly equal length. The extreme tip of the tail is free. 



The face is densely hairy, only the end of the nose and a small 

 space between the eyes and ears being naked. On the upjier lip are 

 moustaches of long hair, and there are a few similar long hairs pro- 

 ji'iting from the chin. The ears are somewhat hairy on their outer 

 surfaces, at the base onlv. ,V11 the membranes are naked.
