384 MR.G.E. DOBSON ON THE GENUS CHALINOLOBUS. [June 1, 
glandular prominences. Lars similar in general outline to those 
of Miniopterus schreibersii ; inner margin of the ear very convex 
forwards in lower half, then sloping almost horizontally backwards 
to the tip, the position of which is determined only by a slight flat- 
tening of the upper third of the outer margin; the lower two 
thirds of the outer margin is slightly convex, and terminates in a 
conspicuous lappet of skin hanging vertica!ly downwards, placed at a 
short distance behind the angle of the mouth, Tragus broad 
above, reaching its greatest breadth above the middle of the inner 
margin; the outer margin hasa slight convexity near the base, above 
it a concavity from which the tragus expands considerably outwards, 
so that the superior part of the outer margin nearly equals the whole 
inner margin in length: the inner margin is straight or slightly 
concave. Lower lip with a distinct fleshy lobe, as in C. tubercu- 
latus. ’ 
Feet small; wings to the base of the toes; postcalcaneal lobe 
rounded, well developed, at a distance equal to the breadth of 
the foot from the end of the tibia; extreme tip of the tail pro- 
jecting. 
On the upper surface the fur extends upon the wing-membrane 
as far as a line drawn from the middle of the humerus to the knee, 
and the base of the interfemoral is occupied by a triangular patch of 
moderately long hairs. Beneath, the hair extends more densely 
somewhat beyond a line drawn from the elbow to the knee-joint, a 
few hairs passing outwards behind the elbow and posterior to the 
forearm and carpus, ranged along part of the oblique parallel lines 
traversing the wing-membrane from the forearm backwards, as in 
Vesperugo noctula. This band of hairs posterior to the forearm is 
found in almost every species of this genus. 
On the upper surface the fur covering the head, neck, and shoul- 
ders is black, with a very faint reddish tinge; posterior to the 
point of origin of the antebrachial membrane the fur is dark at 
the base, the terminal half of the hairs yellowish brown, at the base 
of the tail and upon the interfemoral membrane yellowish brown 
throughout. Beneath, on the breast, the bases of the hairs dark, 
the terminal half reddish or ashy, on the abdomen the extremi- 
ties of the hairs yellowish white, while on the sides of the body 
and on the wing- and interfemoral membranes the fur is pale yel- 
lowish white throughout. 
Inner incisors unicuspidate and long: outer incisors very short, close 
to the outer and anterior sides of the bases of the inner incisors. 
Lower incisors trifid, crowded. First upper premolar exceedingly 
small, so minute as to be seen only with the aid of a lens, wedged 
in between the inner parts of the contiguous edges of the bases 
of the canine and second premolar, as in V. noctula; the second 
premolar is closely approximated externally to the canine, and the 
minute first premolar cannot be seen from without. The first lower 
premolar equals half the second in vertical extent. 
Length (of an adult ¢ preserved in alcohol): head and body 
24; tail 2-2; head 0-75; ear 06x 0"'45, tragus 0!''"28 x
