NYCTONOMUS. 97 
the third finger white, between the first and third fingers black 
mottled with white along the latter. 
Dimensions.—Head and body about three inches ; tail about 
one inch ; forearm nearly three inches. 
Habitat.—South Australia. 
Reference.—Leche, Proc. Zool. Soc. 1884, p. 51, fig. 4 a. (side 
view of head showing lobature of left tragus); B. (right tragus,; c. 
(under view of head showing subsidiary sac ). 
Note.—In enumerating the points of difference between the 
typical 7. affinis of Dobson and his variety insignis, Prof. W. 
Leche lays stress on the color of the wing-membrane between the 
forearm and the third finger, but his description is word for word 
that of Dr. Dobson, so that, unless some clerical error has been 
committed, this difference (?) must be excised. In regard to the 
tragus it is noticeable that the form of the lobature in the, pre- 
sumably typical, example figured is totally different on either 
side, as indeed is noticed by its describer, leading us to surmise 
that this may be the result of accident, or else an individual 
peculiarity ; if this should prove to be the case there is nothing 
by which to separate this form from the typical species, except a 
rudimentary subsidiary gular sac in the male, hardly a sufficient 
difference on which to form even a variety. Prof. Leche can in 
any case be congratulated on having added a very distinct species 
of Taphozous to the Australian Fauna. 
Subfamily II.—Motossinam. 
Tail thick, produced far beyond the posterior margin of the 
interfemoral membrane, which is movable upon it. Legs short 
and strong with well developed fibule. Feet large ; the first toe 
and often the fifth, much larger than the others. Upper incisors 
strong. 
Genus II.—NYCTONOMUS, Geoffroy (1812). 
Extremity of muzzle broad, very obliquely truncated, projecting 
considerably beyond the lower lip, and terminated by the sharply 
cut margin of the nostrils. Ears united on the muzzle, or close 
together by the bases of their inner margins ; tragus short, never 
linear. Upper lip expansible, generally deeply grooved by vertical 
wrinkles. First and fifth toes much thicker than the others; backs 
of all the toes with long curved hairs. Upper incisors close to 
the canines at their bases, separate in front, their cusps converg- 
ing inwards and forwards.
