386 MR. G. E. DOBSON ON THE GENUS CHALINOLOBUs. [June l, 
small naked space on the lip in front of the lower incisors. These 
elevated sides of the chin are covered with short hairs and enclose a 
hollow space between. Ears very like those in Miniopterus, short 
and rather sloped backwards ; the inner margin commences ina 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 slightly 
concave, the outer regularly convex, at the base a rather large 
equilateral triangular lobule very acutely pointed. 
First phalanx of longest finger short, intermediate in length be- 
tween that of Miniopterus and that of Vesperugo, terminal pha- 
lanx 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 ; 
calcaneum long and straight, extending quite three fourths the dis- _ 
tance between the ankle and the tip of the tail; no postcalca- 
neal lobule. 
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 asa 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 
grey. 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. The 
canines are extremely long and slender, and are directed almost ver- 
tically 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 ;
