hollow space between. Ears very like those in Miniopterus, short 

 and rather sloped backwards ; the inner margin commences in a long 

 lobule directed backwards ; the margin of the ear is almost regularly 

 convex all round from the commencement of the inner margin to a 

 point in the outer margin opposite the base of the tragus, where it 

 becomes slightly emarginated, and immediately beyond abruptly 

 convex, forming a short erect lobe connected by a low band with a 

 wart in front at the angle of the mouth, which is continuous with a 

 horizontal lappet of thickened skin extending forwards along the 

 lower lip almost as far as a point opposite the lower canine. With 

 this lappet of the lower lip the outer margin of the ear is thus 

 directly continuous. Tragus semilunate, the inner margin sHghtly 

 concave, the outer regularly convex, at the base a rather large 

 equilateral triangular lobule very acutely pointed (Plate XIV. fig. 5, 

 head, double natural size). 



Pirst phalanx of longest finger short, intermediate in length be- 

 tween that of Miniopterus and that of Vesperugo ; terminal phalanx 

 very long, flexed forwards on the under surface of the first phalanx 

 in repose, in this position it extends nearly to the middle of the 

 metacarpal bone. Feet small ; wings to the base of the toes ; cal- 

 caneum long and straight, extending more than half the distance 

 between the ankle and the tip of the tail (Plate XIV. fig. 5 a). 



Tail as long as the head and body, wholly contained within the 

 interfemoral membrane. 



The ears and the face are nearly naked, a few short hairs only 

 appearing on the glandular'prominences between the eyes and nos- 

 trils ; the fur of the body above and beneath extends upon the wing- 

 membranes as far as a line drawn from the middle of the humerus 

 to the middle of the femur ; the interfemoral membrane above and 

 beneath is quite naked, except where a small triangular patch of 

 hair appears at the root of the tail. 



The fur is tricoloured, the basal third of the hairs black, the 

 middle third white, and the terminal third a beautiful dark silvery 

 grev. This is the arrangement of the colours about the middle of 

 the" body ; but the grey is more prevalent towards and on the head, 

 while the dark shades prevail slightly over the grey towards the 



tail. 



The integument of the ears and face pearly white ; wing- and 

 interfemoral membranes dusky white, translucent, traversed by well- 

 defined reticulations and parallel lines. 



The teeth are very peculiar. The inner upper incisors very long, 

 remarkably slender and acute; the outer incisor on each side fills 

 up the space between the inner incisor and the canine by its broad 

 base ; but its unicuspidate vertically directed summit is very short., and 

 scarcely exceeds the cingulum of the inner incisor (Plate XIV. fig. 5 h). 

 The canines are extremely long and slender, and are directed almost 

 vertically downwards and slightly outwards ; the lower canines are 

 also very slender, but scarcely more than half the length of the 

 upper ones. The upper premolar is very acute and close to the 

 canine ; the posterior upper molar little more than half the size of
