Show 1873.] MR. G. B. SOWERBY ON N E W SHELLS. 721 tuberculatis, tuberculis in costellas infra desinentibus, cum costellis interstitialibus ad basin confluentes; interstitiis fusco strigatis; apertura oblonga, subsinuata; columella superne callosa; labro tenui, sinuoso, serrato ; sinu angusto, profundo ; canali brevi subrecurvo. Hab. ? Shell acuminately turreted, transversely grooved throughout, yellowish streaked with brown; whorls 9, angulated, tuberculated at the angle; tubercles running downwards in ribs which intersect the ribs that proceed upwards from the base; the brown streaks run between the ribs; aperture oblong, somewhat twisted; columella callous at the upper part; lip thin, twisted, serrated; sinus narrow and deep; canal short and slightly recurved. 10. C A R D I U M A R C U A T U L U M , sp. nov. (Plate LIX. fig. 10.) C. testa parva, oblongo-subcordata, obliqua, postice concavo-de-pressa, arcuata ; radiatim costata, costis adjacentibus, confertis, subtiliter crenulatis ; albida, pallida, fulvescente tincta et maculata. Hab. ? A small species of the fragum group, with the posterior margin more arched than in jathers of that group. 11. C O N U S R A C E M O S U S , sp. nov. (Plate LIX. fig. 11.) C. testa cylindraceo-turbinata, subventricosa, solidula, leevi, superne rotundata, spira convexa, apice subobtuso ; fusco-auran-tiaca, lineis obscuris sparsim albo articulatis, transverse cingu-latis, et cumulis macularum albarum trigonarum in series tres distantes dispositis ornata. Hab. Sandwich Islands? (Mus. Frick). Shell cylindrically turbinated, somewhat ventricose, rather solid, smooth, rounded at the upper part; spire convex; apex rather obtuse, of a brownish orange-colour, with obscure transverse lines sparingly articulated with white, and clusters of white triangular spots disposed in three distant rows. Obs. At first sight this shell bears very much the aspect of C. crocatus; but it is of a more ventricose and obtuse form. The disposition of the triangular white spots in distinct distant clusters is a characteristic feature. 12. C A N C E L L A R I A T U R R I T A , sp. nov. (Plate LIX. fig. 12.) C. testa acuminato-turrita, carnea; spira exserta, acuta ; anfractibus circa 7, subplanato-convexis, superne angulatis, ad suturam subdepressis, transverse valide costatis, concentrice obscure plicatis; apertura oblongo-ovata, leevi, labio externo simplici, columella recta, tenuiter triplicata. A Cancellaria of an acuminated turret-form, flesh-colour; whorls 7 in number, rather flatly convex, angulated at the upper part, and somewhat depressed at the sutures, transversely strongly ribbed, and concentrically obscurely plicated; aperture oblong-oval, smooth; outer lip simple; columella straight, with three folds.
