Ears much shorter than the head ; laid forwards, the inner margin of the conch extends slightly further than halfway between the eye and end of the muzzle; inner margins less than one tenth of an inch apart at their bases, uniting on the muzzle in a prominent rounded ridge which ends abruptly at a short distance behind and above the nostrils; inner and outer margins of the ear-conch continuous, forming almost an an arc of a circle; ear-keel short, thickened, but not expanded beneath, clothed posteriorly with short hairs; antitragus circular with a narrow base, as in M. rufus, but thickened and expanded above and posteriorly, so that its very convex superior and posterior margin projects backwards considerably beyond its base; tragus very small, as in 31. rufus, with a minute projection at the outer side of its base. Muzzle very obtuse in front, nearly vertically truncated; nostrils directed forwards and slightly outwards, connected above by au ill-defined ridge which does not extend downwards between them, the wide space between the nostrils and the margin of the upper lip occupied by a quadrilateral patch of thickly spread short hairs, the sides of the muzzle almost naked. A large gular sac in o*, as in M. rufus. Wings from the ankles; interfemoral membrane deep, including quite three fourths of the tail. Fur moderately long, but conspicuously longer than in M. rufus, dark brown above, paler beneath, the base of the hairs whitish on both surfaces. On the upper surface, a band of short fur commences in a narrow line at the beginning of the middle third of the forearm, increases in width outwards so as to cover the proximal third of the fifth metacarpal bone and fourth of the fourth metacarpal, occupying also the portion of wing-membrane between; beneath, the wing-membrane between the humerus and femur is thickly covered, and a band of fur, 0"*3 wide, extends outwards behind the forearm to the fifth metacarpal bone and to the wing-membrane beyond it, covering half the bone. First upper premolar very small, quite external to the tooth-row. Length (of an adult <^ preserved in alcohol) : head and body 3"*1 ; tail 2"*1, tail free from membrane 0"*7; head 0"*9; ear 0"*6, 47* |
