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 pubhc 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. GeofEi'oy are 

 the following : — 1. Rhinolophus 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. Rhinolophus nobilis ; 2. Rh. vulgaris ; 3. Rh. larvatus ; 4. Rh. insignis ; 



5. Rh. deformis ; 6. Rh. affinis ; 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- 

 tilionidee 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 qvie 

 dans chaque region zoologique, quelles qvi'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 vm representant qiii lui appartient 

 sans ambiguite 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- 

 tviting 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 genvis 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 INI. Geoffroy's ideas, would be the 



* I should add, at the same time, that in defining this species — the Pteropus rostratus — I was not regardless of 

 the Pteropus minimus of I\I. Geoffroy ; but as he has placed it in his second divison ** des Roussettes a qmue, Ann. 

 du Mus. XV. p. 97, and as it does not agree in colour with our specimens, I decicled it to be specifically diiFerent.
