exceeding the second premolar in the upijer jaw in vertical extent ; in 

 the lower jaw the second premolar slightly exceeds the canine ; first 

 upper premolar minute, placed slightly inside the tooth-row, but 

 distinctly visible from without.

Ears like those of V. temmincMi, but narrower above, and the 

 tragus resembles that of the preceding species, tapering towards the 

 tip, which is subacutely pointed ; at the base of the outer margin a 

 triangular lobe is placed, succeeded by an emargination, immediately 

 above which the tragus reaches its greatest width, thence it quickly 

 lessens towards the subacute tip ; the inner margin is straight, the 

 outer convex opposite the base of the inner margin and straight in 

 its upper third (Plate XII. fig. 7). The glandular prominences on the 

 muzzle are moderately developed. 



Thumb large : tibia long ; feet very large, the toes more than 

 half the length of the foot ; no postcalcaneal lobe ; last vertebra of 

 tail quite free. 



Above, dark brown at the base of the hairs, the terminal third 

 of the hair light yellowish brown ; beneath similar, but of a lighter 

 shade. 



The fur of the back extends upon the basal half of the interfemoral 

 membrane, and long hairs clothe the leg as far as the ankle ; be- 

 neath, the wing-membrane is covered as far as a line drawn from 

 the elbow to the knee-joint; the base of the interfemoral mem- 

 brane is clothed with long hair, and the rest of the surface with 

 short hairs occurring more densely along the tail. 



The upper incisors are more like those found in the genus Vesper- 

 tilio ; the inner incisor is directed inwards, and has a cusp on its 

 posterior and outer surface ; the outer incisor is directed vertically 

 downwards, is unicuspidate, and about three fourths the length of 

 the inner one. The incisors are thus directed differently, and are 

 separated by a considerable interval at their extremities, as in Ves- 

 pertilio mystacinus, V. adversus, and other species of that genus. 

 The canine is separated by a rather wide interval from the second 

 premolar, through which the small first premolar is distinctly visible 

 from without, and is much larger than in either V. pipistrellus or 

 V. ahramus. The lower incisors are not crowded ; the first lower 

 premolar is less than half the size of the second i)remolar.
