Palate-ridges (fig. 39).—Eive thick and prominent ridges, and two (or three) inconspicuous thin and serrate ridges close together at palation rim.

Second to fiifth ridges divided by a deep groove extending along median line of palate, broadest in front and gradually narrowing posteriorly ; /. Fig. 39.—Palate-ridges of Micropteropus pusillas (). I (linear). thus divided in the middle the ridges form four thick triangular prominences along either border of the groove ; for position of these prominences see figure. External characters.—General aspect as Epomophorus, but muzzle much shorter, centre of eye almost midway between ear and nostril (in Epomophorus much nearer the former), lips less expansible, ears relatively much shorter but scarcely differing in shape, and size of animals smaller. External tail generally more easily detected by touch than by eye (caudal vertebrse three). Interfemoral well developed in centre (depth about 3-6 mm.) and laterally, calcar one- third to one-fourth of hind foot with claws (compare Plerotes). Vertical fasciae of mesopatagium (those crossing in antero-pos- terior direction the main internal cutaneous line) few, 11-16; membranes arising low down on sides of back and inserted poste- riorly at middle or distal half of first phalanx of second toe. Pollex and metacarpals and terminal phalanges of third, fourth, and fifth digits a little longer than in Epomophorus. The table below shows in the upper row the wing-indices of Micropteropus calculated from measurements of eight adult individuals, in the lower row those of Epomophorus for comparison :— 2nd digit. 3rd digit. 4th digit. 5th diffit.
