to affinis, and should therefore have no radiometacarpal pouch.* 
It is distinguished from australis by the presence of a rudimentary 
gular sac in the female, a lobule on the tragus, a much shorter fore- 
arm and tail and by its colour. 
Ear nearly as broad as long, as long in the face from the dorsal 
root of the ear to the end of the nose. Its dorsal margin thickened 
at the root, then palpillate, slightly concave in the middle ; tip 
rounded ; outer (caudal) edge straight, tragus broades and but 
little rounded on the summit, with rounded angles, concave on 
its inner edge, its outer edge straight, but interrupted in the middle 
by a shallow lobule. Lower lip with a triangular cushion on each 
side of its centre, rather remote. Gular sac in the male developed, 
in females represented by a marginal fold of integument and a 
naked area enclosed. Wing from the proximal end of the tarsus ; 
a radiometacarpal pouch. 
Fur. — Muzzle, as far as frontal sulcus, with stout scanty hairs ; 
on the ear the fur of the head extends on the dorsal side of the 
base ; a few long fine hairs on the base within and a very delicate 
fringe of short hair on the summit of tragus, the rest of the ear 
naked ; antebrachial membrane naked on both surfaces ; dorsal 
fur extending on the wing between the middle of the humerus 
and that of the femur, thence a short distance outwards on the 
interfemoral membrane, thence in a curved line to the exit of the 
tail ; tibia and feet naked, or with a few fine hairs between and 
beneath the toes. On the inferior surface the fur of the chin 
extending to the middle of the area in front of the gular sac ; 
on the wing the usual postradial band, the ventral fur extending 
from the middle of the humerus obliquely to the anus, its humeral 
limit prolonged in a narrow band passing along the bone to its 
distal end. 
Colour. — Above dark brown, slightly tinged with yellow, 
the hairs more distinctly ochreous at the base ; beneath, the same 
but paler, the hairs slightly yellower at the base ; ears, membranes, 
and integument uniform black. 
Teeth.— m3 not merely the transverse lamina ascribed 
to the genus by Dobson. It has a sharp median cusp and a posterior 
extension, which assimilate it to the fore lobe of m2. Palatal 
*By the great courtesy of the Curator of the Australian Museum, I have 
been able to examine Dr. Ramsay's type of T. hardgravei, and to affirm the 
absence of the pouch. When Dr. Dobson wrote that the supposed want of a 
gular sac was the only important difference between T. hardgravei and flaviventris, 
he must have overlooked the fact that Dr. Ramsay considered his species allied 
to affinis, and consequently one that did not possess the distinguishing 
character of the group to which flaviventris belongs. T. hardgravei is a sound 
species and a fine one.
