Ilab. Unknown. 

 _ This very peculiar species of Vesperugo resembles V. Jcuhlii in 

 size and in general form ; but the absence of the first minute upper 

 premolar and the shape of the muzzle at once distinguish it. The 

 shape of the muzzle is so peculiar as to lead me to suspect it may 

 be an mdividual peculiarity. As the specimen from which the de- 

 scription is taken is well preserved in alcohol, this flattening of the 

 front of the muzzle and extremities of the nostrils is not due to im- 

 perfect preservation.

Head scarcely raised above the face-line. Ears moderately long, 

 inner margin above the basal lobe slightly convex to the tip, which 

 is shortly rounded off ; nearly the upper half of the outer margin 

 concave, the lower convex, slightly emarginate opposite the base of 

 the tragus, and terminating midway between the posterior margin 

 of the tragus and the angle of the mouth in a distinct lobe. The 

 tragus reaches its greatest width slightly below the middle of its 

 inner margin ; at the base of the outer margin is a small triangular 

 lobe, succeeded by a shallow concavity, above which the tragus 

 reaches its greatest width, and the outer margin then curves in- 

 wards and slightly upwards to form the narrow rounded extremity, 

 which is slightly curved inwards owing to the concavity of the upper 

 third of the inner margin. The glandular prominences between the 

 nostrils and the eyes are well developed and smoothly rounded, and 

 the nostrils do not project. 



Wing-membranes to the base of the toes ; postcalcaneal lobes very 

 narrow or absent ; the extreme tip of the tail alone free ; feet rather 

 large and thick. 



Above and beneath, the hair of the body extends upon the wing- 

 membrane as far as a line drawn from the middle of the humerus to 

 the knee-joint ; the base of the interfemoral about the root of the 

 tail is alone covered. Beneath, a few fine hairs arise from the trans- 



* The type of Vespertilio hesperida, Temni., is not now to be found in the 

 collection of the Leyden Museum.
