XVI HORSE-SHOE BATS ED 
none; occasionally there are two. It has no claw. The ear has 
its two sides separate from their point of origin upon the head. 
The group is of Old-World distribution. 
-Fam. 1. Rhinolophidae.—The Bats of this family possess the 
leafy outgrowths around the nostrils. The ears are large, but 
have no tragus. The index finger has no phalanx at all. The 
premaxillary bones are quite rudimentary, and are suspended from 
the nasal cartilages. In addition to the pectoral mammae they 
have two teat-like processes situated abdominally. The tail is 
long, and extends to the end of the interfemoral membrane. 
The genus Rhinolophus has a large nose leaf, and an anti- 
tragus to the ear. The first toe has two joints, the remaining toes 
have three jointseach. The dentition is] $ C+ Pm2M23. There 
are nearly thirty species of the genus, which are restricted to the 
Old World. Two species occur in this country, viz. R. ferrum 
equinum, the Great Horse-shoe Bat, and the Lesser Horse-shoe Bat, 
Re hipposiderus. The name is of course derived from the shape 
of the nose leaf. 
The genus Hipposiderus and some allied forms are placed 
away from Rhinolophus and its immediate allies in a sub-family 
H@posiderinae. The type genus Hipposiderus, or, as it ought 
apparently to be called, Phyllorhina, is Old World in range, like 
all the other members of the family. 
The nose leaf is complicated, and there are only two phalanges 
in all the toes; there is no antitragus to the ear. A curious 
feature in the osteology of the genus, and indeed of the sub-family, 
is the fact that the ileo-pectineal process is connected with the 
ium by a bony bridge; this arrangement is unique among 
mammals. 
The genus Anthops, only known from the Solomon Islands, 
and represented there by but a single species (4. ornatus), has 
an extraordinarily complicated nose leaf. The tail, like that of 
the Oriental Coelops, likewise represented by a single species 
(C. frithiz), is rudimentary. 
Triaenops, Ethiopian and Malagasy, has, like the Australian 
Rhinonycteris, a well-developed tail. Z'riaenops has also a highly- 
coinplicated nose leaf. 
Fam. 2. Nycteridae.—This family is to be distinguished from 
the Rhinolophidae by the fact that the ear has a small tragus, 
and by the small and cartilaginous premaxillae. In addition to
