 The Pacific Volute. Shell oblong-fusiform, rather 

 veutricose, spire more or less exserted, scarcely papil- 

 lary at the apex, whorls smooth, tubercled rmmd the 

 upper part, tubercles sometimes rather prominent, 

 sometimes almost obsolete, columella four- to five- 

 plaited, often forming an expanded lamina, aperture 

 oblong, lip slightly reflected ; light flesh-brown, en-

 Hab. Van Diemen's Land. New Zealand. 



The light ventricose variety of this species, constituting 

 the V. eloiKjala of Swainson, is of much more common 

 occui-rence than that which is strongly tubercled. The 

 latter variety, always more richly marked, was distinguished 

 by Favanue with the name of 'La robe Turque.' Most 

 specimens have a thin lamina expanded over the columella.

The captive Volute. Shell elongately oblong, some- 

 what fusiform, rather thin, spire exserted, peculiarly 

 twi.sted and but little papillary at the apex, whorls 

 convex, rather smooth, columella two- three-plaited, 

 aperture rather narrow, lip simple ; pale fulvous, 

 painted here and there wdth longitudinally waved 

 brown streaks.

TuE SLENDER VoLUTE. Shell oblong-fusiforui, spire 

 exserted, papillary at the apex, whorls smooth, 

 slanting round the upper part, then ribbed in a 

 swollen manner, ribs gradually fading, columella 

 four-plaited, aperture oblong, lip rather thickened ; 

 pale fulvous colour, jiaintcd longitudinally with waved 

 chestnut lines.

Hab. Australia. 



By exhibiting this species anil the V. Pacijica in juxta- 

 position, each of the natural size, theii' distinctive character 

 may be readily understood. The V. gracilis is uniformlv 

 of much smaller size, the tubercles have the form of swol- 

 len ribs, and there is no expanded columellar lamina.
