RHINOLOPHUS LABVATUS, 
of Java. The genus Rhinolophus is one of the most remarkable among the family 
of Vespertilionidse. The individuals which compose it, are distinguished, even on a 
superficial view, by ears of excessive size, broad at the base, erect and acuminate, 
and by a greatly complicated nasal membrane. But the most striking character, 
which belongs to it exclusively, is the presence of two papillary tubercles, situated 
on the os pubis, and exhibiting the external appearance of two breasts. This cha- 
racter, as far as my inquiries extend, is first distinctly noticed by Bechstein. The 
female, he remarks, has, to appearance, four teats, two on the breast, and two on the 
region of the pubes ; the latter he always found relaxed, as if the young had drawn 
milk from them by sucking, as well as from the others. Mr. Geoffroy notices this 
character, with the following remark : " besides the two pectoral breasts, which are 
the only organs for the secretion of milk in the other Vespertilionida?, the Rhinolophi 
have two others, situated near each other, above the os pubis." He recommends this 
character to the attention of naturalists, and it doubtless deserves more careful inves- 
tigation. M. Desmarest, in his character of Rhinolophus, describes two pectoral 
mammse, and two warts, situated on the pubes (deux vermes pubiennes), having the 
appearance of breasts, but being destitute of lactiferous glands. M. KuhVs observa- 
tions on tliis subject shew, that during the first year, these lower teats are altogether 
wanting, that they are minute in the female of two years, and that only in the third 
year they acquire their full size. It appears to Mr. K. that, although connected with 
the propagation of the species, they are not breasts, as he never discovered lactiferous 
glands near them. They are connected with the cavity of the pelvis. 
The ears of the Rhinolophi resemble those of the Pteropi, in the simplicity, of 
their structure. They consist of a large membranaceous lobe, very broad at the base, 
tapering towards the extremity, but without that enlargement of the tragus, which 
constitutes the oreillon in the other insectivorous Vespertilionidae, and which affords 
them the power of rendering themselves deaf at pleasure. This organ is subject, 
however, to several variations of form, which will be described in enumerating the 
characters which have been employed in the specific distinctions. 
With the simplicity of the ears, the complicated structure of the nose forms a 
striking contrast ; this exists as well in those parts which are concealed by the in- 
teguments, as in those which are exposed to view. The external entrance to the 
olfactory organs consists of several membranes, variously disposed and folded, so as 
to constitute a funnel, the object of which is, to direct the olfactory particles to the 
nasal chambers, which occupy an extensive cavity in the anterior part of the skull. 
The lowest exterior portion of the membranaceous apparatus consists of the apertures
