RHINOLOPHUS LARVATUS. 
of the nares, which are confined by a delicate membrane, and have a circular or oval 
form. These are bounded, at the sides and underneath, by one or by several folds of 
a membrane, which has some resemblance to a horse-shoe, whence the name of 
Horse-shoe Bat has, from time immemorial, been applied to the European species 
of Rhinolophus. Above, these nasal apertures are defined by a large membrane, 
which either rises perpendicularly to a point, in form of a lance, or stretches 
transversely across the nose, and constitutes a prominent arch or conch. These are 
the two principal forms which have been observed in the membranaceous appa- 
ratus of the Rhinolophi, and according to which they may be divided into two 
sections ; but each has again several modifications, which serve to distinguish the 
species. A cartilaginous partition of the nose projecting forward, which is called the 
crest, and which may be compared to the bill of a cock, surmounted by its comb, 
exists in several of those species, in which the superior membrane is lance-shaped 
and erect. In considering this nasal apparatus, it should be observed, that it is 
likewise a character in several other genera of this family, but in Rhinolophus it 
lias by far the greatest degree of development. 
The structure of the lips is very complicated: some of the fibres separate, and 
are extended to the forehead, leaving a vacancy, which has been compared to a 
funnel, at the bottom of which the nostrils are situated. The tail is long and entirely 
enveloped in the interfemoral membrane ; its relative proportion to the legs, affords 
a character which is employed in the discrimination of the species. The fur is gene- 
rally characterized by a great length and softness; in several of the Javanese species 
it possesses, on the upper parts of the body and on the breast, an uncommon degree 
of tenderness and delicacy. 
The Rhinolophi belong to the second tribe, established by M. G. Cuvier, among 
the Insectivorous Bats ; in this, the phalanx of the index is single, short, or rudi- 
mentary, and each of the other fingers has only two phalanges. Of the other genera 
which are contained in the Museum of the Honourable East India Company, Mega- 
derma, Nycteris, and Vespertilio, also belong to this tribe. 
The teeth are very uniform in all the Javanese species of Rhinolophus ; their 
structure is clearly exhibited in the natural character ; a few slight modifications of 
the front teeth, above and underneath, will be noticed in the detail of the species. 
In describing the Rhinolophi, wliich I have collected in Java, I have to acknow- 
ledge my obligation to Mr. Geoffroy, for the general illustration of this genus, which
