able for feeding on fish—a circumstance which has only recently 
been fully authenticated. 
The remaining genus of this subfamily is regarded as repre- 
senting another division, which may be known as the Lhinopomu- 
tine division. : 
Lhinepoma.|—This genus, represented by the single species 
R. micrephyllum, might also be elevated to the rank of a family, for it 
is difficult to determine its exact 
affinities, a kind of cross relationship 
attaching it to the \ycteride on the 
one hand and to this family, in which 
it is here placed provisionally, on the 
other. This species, distinguished 
from all other Microchiroptera as well 
by the presence of two phalanges in Fic. 314.—Skull of Rhinczoma micro-

long and slender tail projecting far sai 
beyond the narrow interfemoral membrane, inhabits the subterranean 
tombs in Egypt and deserted buildings generally from North-East 
Africa to Burma. 
Subfamily Molossine.—Tail thick, produced far beyond the 
posterior margin of the interfemoral membrane (except in J/ysta- 
cops); legs short and strong, with well-developed fibula; upper 
incisors strong. This subfamily includes all the species of Emba/- 
lonuride with short and strong legs and broad feet (whereof the 
first toe, and in most species the fifth also, is much thicker than 
the others, and furnished with long curved hairs), well-developed 
callosities at the base of the thumbs, and a single pair of large 
upper incisors occupying the centre of the space between the 
canines. In all the species the feet are free from the wing- 
membrane, which folds up perfectly under the forearm and legs; the 
interfemoral membrane is retractile, being movable backwards and 
forwards along the tail, and this power of varving its superficial 
extent must confer upon these Bats great dexterity in quickly 
changing the direction of their flight, as when obliged to double in 
pursuing their swift insect prey, which their extremely expansible 
lips evidently enable them to secure with ease. Like the preceding 
subfamily, the genera may be arranged in divisions, of which there 
are two. 
The Jfolossing division is characterised by the production of the 
tail beyond the posterior margin of the interfemoral membrane ; it 
includes three senera.
