not otily 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- 

 equinum, — the second section of Temminck's ' Monographies,' — and 

 approaches most nearly to the R. euryatis 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 

 membrane is the same as in luctus, and similarly notched in front. 

 The foremost of the two elevated appendages is nearly the same, but 

 the lateral lobes at the base are less produced and considerably 

 smaller ; joining these lobes on each side is a small membranous 

 fold extending outwards and backwards, and is attached to the 

 horse-shoe membrane. The posterior lobe is lanceolate and more 

 pointed than in luctus, has a transverse fold near its base as in that 

 species, and is joined to the anterior truncated elcA^ated lobe by 

 a longitudinally elevated membrane. The height of the posterior 

 lanceolate lobe is 3;^ lines, and of the anterior lobe 2J lines, or rather 

 more. On the side of the muzzle is a longitudinal fleshy ridge. The 

 chin presents four warts, two at the tip and one on each side of these. 

 The extreme point of the tail is free, the free portion being however 

 not more than half a line in length. 



Lastly, Mr. Waterhouse called attention to a new species of Me- 

 gaderma.
