 Pulmonate. 



Fischer, P.— Remarques sur I'opercule du g. Naticina Gray 

 (Remarks on the operculum of the genus Naticina), pp.215 — 216. 



The appendage near the nucleus of the operculum of N. pap- 

 illa Gmelin, is not peculiar to the genus, but exists plainly in that 

 of Sigaretus Icevigatus Lamarck. Naticina is therefore probably 

 only a subgenus of Sigafetus, and the name must be changed hav- 

 ing been previously used by Guilding.

Zonites Hamelianus Crosse, (Pl.ix. f i) Bale du Sud ; Helix 

 Vimontiana Cr. (f2) Noume'a, a bulimiform species; Bulimus 

 porphyrostomus Pfr. var. S (Pl.viii. £2) He des Pins ; distinguished 

 by its white aperture ; B. Ouvea^ius Dotzauer var. 7 (£4) Siande, 

 also with a white aperture ; B. Hienguenensis Cr. (f.3) Hienguen 

 and Ouagap ; This species was originally described by Pfeiffer as 

 B. Eddystonensis under the mistaken impression that it came from 

 Eddystone Island in the Solomon Archipelago ; Cyprcea ?iigricafts 

 Montrouzier, (Pl.viii. £5. and Pl.ix. £3) Kanala; It is doubtful 

 whether this is a distinct species, or a black variety of C. mappa. 



Crosse, H. — Note sur une espece manuscrite de M. le pro- 

 fessor G. P. Deshayes (Note on a manuscript species of Professor 

 Deshayes), pp. 223 — 225. 



M. Crosse himself doubts very much whether this species, 

 Conus pseiidotnaruioreus Deshayes, is really distinct from Coims 

 marmoreus. The only points of difference are the smaller size, 

 more raised spire, and the very marked transverse striae of the last 

 whorl ; Judging from the figure (Pl.ix. £4) it would seem to be 

 hardly distinct.
