1873.] MR. G. B. SOWERBY ON NEW SHELLS. 721 



tuberculatis, tuberculis in costellas infra desinentibus, cum 

 costellis interstitialibus ad basin confluentes ; interstitiis fusco 

 strigatis ; apertura oblong a, subsinuata ; columella superne 

 callosa ; labro tenui, sinuoso, serrato ; sinu angusto, prof undo ; 

 canali brevi subrecurvo. 



Hab. ? 



Shell acuminately turreted, transversely grooved throughout, yel- 

 lowish streaked with brown ; whorls 9, angulated, tuberculated at 

 the angle ; tubercles running downwards iu 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. Cardium arcuatulum, sp. nov. (Plate LIX. fig. 10.) 



C. testa parva, oblong o-subcor data, obliqua, postice concavo-de- 

 pressa, arcuata ; radiathn costata, costis adjacentibus, confertis, 

 subtiliter crenulatis ; albida, pallida, fulvescente tincta et ma- 

 culata. 



Hab. ? 



A small species of the fragum group, with the posterior margin 

 more arched than in others of that group. 



11. Conus racemosus, sp. nov. (Plate LIX. fig. U.) 



C. testa cylindraceo-turbinata, subventricosa, solidula, Icevi, su- 

 perne 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? (Mm*. 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 if is of a more ventricose and obtuse form. The dis- 

 position of the triangular white spots in distinct distant clusters is a 

 characteristic feature. 



12. Cancellaria turrita, sp. nov. (Plate LIX. fig. 12.) 



C. testa acuminato-turrita, carnea ; spira exserta, acuta ; anfrac- 

 tibus circa 7, subplanato-convexis, superne angulatis, ad sutu- 

 ram subdepressis, transverse valide costatis, concentrice obscure 

 plicatis ; apertura oblongo-ovata, Icevi, labio externo sitnplici, 

 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.
