Sh.e.l.l ovate conical, livid purplish-white, with one or two central, obscure brown, bands; upper whorls bluntly transversely plaited, the rest smooth, livid, except at the front part of the last, just over the groove, where it is spirally striated; the suture distinct (not channelled) marked by a white line; the inner lip distinct, raised, the outer thickened on the outer side, edge sharp, inside grooved; the throat fulvous-brown; axis one inch, diameter half an inch.

This sh.e.l.l belongs to the group of Na.s.sa, but will perhaps form a distinct genus intermediate between it and Columbella, characterized by the narrow form of the mouth. It is most nearly allied to N. olivacea, n.

(Bucc. olivaceum, Lam.) and N. ca.n.a.liculata, n. (Bucc. ca.n.a.liculatum, Lam.)

58. Clavatula striata (n.s.)

Testa ovato-lanceolata turrita albida regulariter spiraliter sulcato-striata transverse et interrupte costata, anfractuum margine superiore angulato subnodoso, cauda brevi, fauce sulcata.

Icon. --

Sh.e.l.l ovate turreted, whitish-brown, with eleven or twelve longitudinal interrupted ribs forming long tubercles on the centre of the whorls; the whorls with distant impressed spiral lines near the suture, with a rather flattened slightly nodulose band; the mouth rather more than one-third the length of the sh.e.l.l; outer lip thin inside, grooved; tail short, with a linear depression on its columella side; axis ten-twelfths, diameter four-twelfths of an inch.

59. Ca.s.sis achatina, var. Lam. Hist. 7 226.

A worn specimen, apparently a variety of this species. It is entirely smooth, polished, and has the last whorl near the spire slightly concave, edged with a scarcely raised rather nodulous line, the outer lip is very thick, grooved on its inner edge, and the columella is distinctly plaited.

It may perhaps prove to be a new kind; but the species of this genus are so exceedingly apt to vary, that I do not wish to increase the number of the already too much extended lists of Lamarck and others.

This sh.e.l.l agrees very well with the description of Lamarck, except that the whole edge of the mouth is of a fine rose-red colour.

This sh.e.l.l is very like Triton scobinator, Lam.; and the varices, like it, neither form a complete series, nor are they alternate, so that it does not agree exactly with the characters of either genus.

Sh.e.l.l very plain, top-shaped, crowned, and whitish, with two brown bands; spire rather depressed; crowned, blunt; the epidermis pale greenish-brown; the inside white, with two broad blue bands, in the front of which is enclosed the ca.n.a.l; axis one and a half, diameter one inch.
