Show 384 MR. G. E. DOBSON ON THE GENUS CHALINOLOBUS. [June 1, glandular prominences. Ears similar in general outline to those of Miniopterus schreibersii ; inner margin of the ear very convex forwards iu lower half, then sloping almost horizontally backwards to the tip, the position of which is determined only by a slight flattening 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 vertically 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 has a 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. tuberculatus. 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 projecting. O n 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. O n the upper surface the fur covering the head, neck, and shoulders 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 extremities of the hairs yellowish white, while on the sides of the body and on the wing- and interfemoral membranes the fur is pale yellowish 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 2"*4; tail 2"*2 ; head 0"*75 ; ear 0"*6x0"*45, tragus 0"*28x |
