June 1847. Expedition Shells, 44. 
SHELL elongated, turreted, solid, olive-green, with flexuous longitu- 
dinal, dusky stripes between the folds, sometimes banded also with 
numerous well-marked, crowded, acute, longitudinal folds, fifteen to 
twenty or more in number, and everywhere covered with coarse, 
raised, revolving lines, which cross the folds, and render them some- 
what beaded, and which are coarser, and often alternately larger and 
smaller towards the base. ‘There are about four moderately convex 
whorls, and the apex is much eroded. There is a slight angle above 
the middle, where the revolving line rises into a small, sharp tubercle. 
Aperture about one-third the length of the shell, narrow elliptical, 
bluish within ; lip sharp. 
Length one inch; breadth one-fourth of an inch. 
Inhabits the Feejee and Samoa Islands. 
Of the same group as the preceding, but more slender, and re- 
markable for the lyrate appearance produced by its numerous folds, 
decussated by revolving lines, one of which, more conspicuous than 
the rest, forms a sort of beaded angle.

cimen. 
Metania scipio (Gould). 
Testa magna, solida, lanceolata, truncata, picea, sursum rufescens et

minutissime decussato-striata: spira anfractibus superstitibus quatuor
