Show 1888.J MR. G. B. SOWERBY ON NEW SPECIES OF SHELLS. 2(»9 zona angusta, albida, interrupta, infra medium cincta. Spira elata, acuminata; sutura impressa ; anfractus 11, leviter convexi ; primi 2\ politi, simplices; sequentes 4, costis Icevigatis, rotundatis instructi; cceteri Icevigati, subtilissime striati oblique malleati; ultimus vix ventricosus, spiram leviter superans, infra medium valde contractus, oblique sulcatus, in caudam brevem recurvam desinens, et canalem aperturalem formans. Apertura ovato-oblonga, spiram subcequans, fauce pallide violacea ; columella polita, albida, fusco tincta, superne plica unica, minuta, curvata munita, ad medium, angulata; labrum acutum, extus leviter incrassatum, intus subobsolete liratum. Long. 30, maj. lat. 12 millim. Hab. South Sea ? A fine handsome species, one of the largest of the genus, and entirely different from any hitherto known or described. I found two perfect specimens of this species in the collection of the late Mr. D. Filby of Hamburg with a label " South Sea," but even this indefinite locality is not to be relied on. The largest of the two, which I have taken for the type, forms part of the gift made by Mrs. Filby to the Hamburg Museum. The second specimen is about 27 millim. in length, and of the same form, proportions, colour, and markings as the type. CORALLIOPHILA TURRITA, sp. nov. (Plate XI. fig. 11.) C. testa elongala, turrita, albida, pallide roseo tincta. Spira per elata ; anfractus 9, lente accrescentes, convexi, obscure angulati, suboblique plicati (plicis rotundatis, confertiusculis), vbique spiraliter dense squamoso-lirali; anfr. ultimus parvus, rotundatus, infra medium contractus, et aliquanto product us. Apertura ovata ; columella infra medium acute angulata ; canali brevissimo ; labrum crenulatum. Long. 23, maj. diam. 9, apert. long. 6, lat. 4 millim. Hab. Mauritius. A very narrow turreted species, with a small mouth, long spire, and ribbed, scabrous, slightly angular whorls. TROCHUS (GIBBULA ?) PONSONBYI, sp. nov. (Plate XI. fig. 5.) T. testa subglobosa, anguste umbilicata, tenuiuscula, pallida, ad basin fusco maculata. Anfractus 5, convexi celeriter accrescentes ; primi 2 Iceves ; cceteri angulati, ad angulum serie tuberculorum coronati ; supra angulum spiraliter trisulcati ; infra obscure lirati. Anfr. ultimus inftatus, superne serie tuberculorum (circ. 12) coronatus; infra corona uniliratus ; ad basin convexus, ventricosus, rotundatus, liris (circ. 8) acutius-culis instructus. Apertura semilunaris; columella tenuiter callosa, superne contractu, infra medium turgidula. Alt. 13|, diam. 14, apert. long. 9, maj. lat. 7 millim. Hab. Port Elizabeth, South Africa. In the absence of the operculum it is impossible to say with certainty to what genus or section this species belongs, although I |
