 part, tubercled and sharply squamate at the angle, 

 columella very strongly four-plaited, aperture oblong,

Hab. 



The r. Inleostouia is very distinctly characterized by its 

 scjuare thickened growth, squamate tubercles, and pattern 

 of colouring, consisting externally of a very dark brown 

 transverse net-work, and internally of a bright saffron 

 yellow. Martini's figure of the species, Conch. Cab. vol. iii. 

 pi. 07. f. 930, appears to have escaped observation.

The LYRE-SHAPED Volute. Shell fusiformly turreted, 

 spire acuminated, very much produced, globosely 

 papillary at the apex, whorls convex, longitudinally 

 closely ribbed throughout, ribs and interstices longi- 



tudinally striated, last whorl transversely grooved in 

 u wi-inkled manner at the base, columella many- 

 plaited, lower plaits larger, the rest small, aperture 

 rather small, oblong, pale flesh-colour, painted in a 

 banded manner with blue, chestnut, and reddish spots 

 and lines.

llab. East Coast of Africa. 



This beautiful shell in our national collection, the only 

 one of the species at present known, is remarkable for its 

 elongated growth, ribbed sculpture and richly variegated 

 painting. 



The shell figured by M. Kiener for rolula lyr/pfunnin 

 appears to be the V. mcgaspira which follows.

The LARGE SPIRE Volute. Shell fusiform, turreted, 

 rather thin, spire elongated, exserted, apex globosely 

 papillary, whorls transversely finely striated, longitu- 

 dinally plicately ribbed, ribs gradually fading towards 

 the aperttire, columella five-plaited, upper ))laifs 

 small, somewhat obsolete, aperture oblong, rather 

 small, lip scarcely thickened; light flesh-brown, irre- 

 gularly blotched and waved with reddish clir>rnut.

Hab. Japan; Siebold. 



This elegant fusiform species is of rather light growth, 

 deUcately plicately ribbed, the ribs being sharp and com- 

 pressed, and nearly obliterated on the last whorl. Tlu' 

 specimen here figured from Mr. Cuming's collection, was 

 l)rought from Japan by Dr. Siebold. There is a specimen 

 in the collection of M. Delessert in Paris, figured erro- 

 neously by Kiener for the V. Igrceformis, and another 

 in the Museum at Levden.
