RHINOLOPHUS LARVATUS. 
is given in his Memoir on the Rhinolophes, contained in the XXth VoL of the 
Annales du Museum, &c. This Essay contains also the most copious list of species 
which has hitherto been communicated to the public Mr. Geoffroy enumerates six ; 
these have all been adopted by M. Desmarest, in his * Description des Especes de 
Mammiferes," in the Encyclopedia- The species enumerated by M. Geoffroy are 
the following :— 1. Rliinolophus uni-hastatus ; 2. Rh. bi-hastatus ; 3. Rh. tridens ; 
4. Rh. speoris; 5. Rh. diadema ; 6. Rh. Commersonii. To these I have added from 
Java, 1. Rliinolophus nobilis ; 2. Rh. vulgaris; 3. Rh. larvatus; 4. Rh. insignis; 
5. Rh. deformis ; 6. Rh. affinis j 7. Rh, minor. A comparative view of these species 
will be given in the sequel : their number and peculiar modifications, appearing both 
in Asiatic and European forms, together with the species of other families of Vesper- 
tilionidse which are found in Java, tend to illustrate a very appropriate remark of 
M. Geoffroy, which I shall give in his own words : " n'est-il pas remarquable que 
dans chaque region zoologique, quelles qu'en soient les distances, les chauve-souris 
aient une organization qui rentre rigoureusement dans une de nos families, au plutot 
que chaque famille ait dans chacune de ces regions un representant qui lui appartient 
sans ambiguity come sans partage ?" But I may observe here, that as investigation 
extends, new types are discovered. One of these is exhibited in the Pteropus ros- 
tratus, of the Third Number of these Researches, which M. Fred. Cuvier has sepa- 
rated from the Pteropus, and described as a distinct genus * 
M. Geoffroy further points out the peculiarities of the Rhinolophi, as consti- 
tuting a genus more strictly limited and circumscribed in its characters than most 
others. One of the Javanese species in our collection deviates in a small degree from 
this peculiarity, so that I have been led to suppose that the structure of the head, and 
the erect disposition of the nasal membrane, as well as the character of the tail, tend 
to shew that it forms an approach to the genus Megaderma. It has been named 
deformis. For the present article I have selected that species, in which the peculiar 
character of the inguinal protuberances is strikingly apparent. 
The Javanese Rhinolophi may be generally divided into two sections ; the first 
having the superior lobe of the nasal membrane erect and lanceolate — the second hav- 
ing above a transverse membrane, stretching forward as a small arch. Of the former 
I have found two species, which, according to M. Geoffrey's ideas, would be the 
* I should add, at the same time, that in defining this species — the Tteropus rostratus — I was not regardless of 
the Pteropus minimus of M. Geoffroy ; but as he has placed it in his second divison ** des Ronissettcs & queue, Ann. 
du Mus. XV. p. 97, and as it does not agree in colour with our specimens, I decided it to be specifically different.
