of the nose are of considerable extent, and, taken together, they 
form an oval figure; this is transversely divided near the middle 
by a slight fleshy ridge; the membrane in front of this ridge, and 
which encircles the nostril-openings, has its edges free, and on 
each side of the muzzle are two distinct longitudinal narrow folds 
of membrane, situated partially under the free edge of the mem- 
brane which encircles the nostrils: behind the transverse mesial 
ridge is what may be termed the posterior nose-leaf; this is of a 
semicircular form, has its margin thickened and raised, and send- 
ing forwards to the transverse ridge just mentioned three small 
ridges, dividing the interspace into four little hollows or pits. The 
ears are of moderate size, acute at the point, and have the outer 
margin distinctly emarginated. On the lips are some indistinct 
warts, and on the tip of the lower lip are two which are more pro- 
minent and distinct. 
The R. pygmaus approaches somewhat to the R. bicolor, but differs 
not only in colour, but in having the ears smaller and distinctly emar- 
ginated externally ; the hinder nose-leaf is larger. It approaches in 
size the R. tricuspidatus. ‘The ears are larger than in that species, 
and the nose-leaf is also larger, considerably more extended in the 
antero-posterior direction, and differs moreover in structure.

This species belongs to the same section as the Rhinolophus ferrum- 
eguinum,—the second section of Temminck’s ‘ Monographies,’—and 
approaches most nearly to the R. euryotis of that author, from which 
however it may be readily distinguished by the much larger size of 
the accessory lobe of the ear, and the truncated form of the foremost 
of the two membranaceous nasal appendages. It also approaches, in 
the large size of the ears and great development of the nasal appen- 
dages, the R. luctus of Temminck, but is of smaller size; the ears 
are rather less acutely pointed; the accessory lobe at the base is 
longer and proportionally narrower, and the proportions of the nasal 
membrane differ. In spirit the colour of the fur is very dark brown ; 
on the under parts of the body rather paler than on the upper, and 
inclining to greyish. The nasal membranous appendages are very 
complicated, and being evidently on the same type as the R. luctus, 
I will compare them with the corresponding parts as shown in Tem- 
minck’s figure of that species. ‘The large decumbent horse-shoe
