it encloses the thumb. The interfemoral membrane margins the 
coccyx and legs, and is at the os calcis not more than 2 lines wide, 
at the coccyx the same, but at the knee as much as 5 lines wide. 
All the face is covered with very short fine hair, with the exception 
of the muzzle, chin, and edges of the lips, which are naked. On the 
upper lip, towards the end of the nose, are a few scattered longish 
bristle-like hairs. The fur of the back extends on to the fore-arm 
for half its length, on to the hinder limbs for nearly the whole of 
their length, and on the membranes of the flanks for the breadth of 
half an inch. Nearly the whole of the interfemoral membrane has 
its upper surface hairy, the exception being at the os caleis. Be- 
neath, the fore-arm membranes of the flanks and legs are similarly 
hairy, but more sparingly so, especially those of the latter. 
Both above and beneath, nearly all that part of the wing-mem- 
branes which is between the last finger and the body is studded with 
rows of glandular dots, each bearing a little bundle of short hairs, 
most regular on its upper surface. All the other parts of the mem- 
brane are semi-opaque, and rather distinctly veined. 
The fur of all parts of the body is short and soft, above longer and 
thicker than beneath ; it is unicolour, and of a lightish cinnamon- 
brown, with an ill-defined oval patch on the abdomen of a cream 
colour. At the base of the ears are two little patches of soft white 
fur, just on their margins; and on the shoulder is the remarkable 
tuft of long white hairs which was first noticed by Mr. Bennett, and 
at that time regarded as peculiar to the species.

Pipe OL WINES. 22a. 2 So a 8 Pe eae | 
* The spread of the wings is never a very satisfactory dimension in the Cheiro- 
ptera, for in such species as those constituting the present genus, in which the 
wings are broad and the fingers much curved, it is obvious that the real expanse 
of the wings is not given by following their curvature. On the other hand, if 
the measure taken be a straight line between the tips of the open wings, that 
line must necessarily vary in length with the degree to which they are opened—
