The mouth of a very large gular sac, larger than in any other known species of this genus, extends across the throat from a point on each side near the anterior termination of the antitragus, opening forwards as in Taphozous. Wings from the distal third of the tibia. Fur moderately long; above dark reddish-brown, beneath paler; the base of the hairs on both surfaces much lighter. On the dorsal surface the wings are covered as far as a line drawn from the middle of the humerus to the distal third of the femur, also the base of the interfemoral as far as a line drawn between the knees; beneath, a narrow band of fur extends outwards behind the forearm, becoming wider in the angle between the forearm and the fifth metacarpal bone, along which it extends for half its length, and, passing over, covers the space between it and the upper third of the fourth metacarpal.
