Show 600 MR. G. B. SOWERBY ON NEW SPECIES OF SHELLS. [Nov. 3, Hab. Hongkong (Cuthill). The characters of this species are much the same as those of <8. Septimus (Duclos), of which Mr. Cuthill has sent me several specimens from the same locality; but the form is very different, the latter being a narrow shell of the form of S. succinctus (Linn.), which is found in Ceylon. 4. COLUMBELLA (ANACHIS) SINUATA, sp. nov. (Plate LXXII. figs. 2, 2 a.) C. testa fusiformi, rufo-fusca, caruleo-albo et brunneo variegata, tenui, pellucida; spira acuminata ; anfractibus 9, planato-convexis, lavibus, longitudinaliter regulariter valide costatis costis ad anfr actum ultimum, versus marginem medio tubercu-latis; apertura oblonga, intus carulea, costata; columella corrugata, tenuiter encaustica ; canali brevi, profundo, recurvo; labio externo superne elevato, expanso, incrassato, medio sinu lato profundo emarginato : long. 17, lat. 9 mill. Shell fusiform, reddish brown, variegated with bluish white and dark brown, thin, transparent; spire acuminated ; whorls nine in number, flatly convex, smooth, strongly ribbed longitudinally; the ribs on the last whorl towards the margin tuberculated in the middle, transversely ribbed at the base; aperture oblong, interior blue, ribbed; columella wrinkled, covered with a transparent, shining enamel ; canal short, deep, recurved; outer lip thickened and expanded at the upper part, and with a broad deep sinus in the middle. Sab. Upper California. A very remarkable little shell, almost generically distinct from any hitherto known species; T think, however, it truly belongs to the section Anachis (H. & A. Adams). The sinus is almost like that of a Pleurotoma ; only it is in the middle of the lip. 5. AMPULLARIACATAMARCENSIS, nov.sp. (Plate LXXII. fig.4.) A. testa subglobosa, imperforata, solidiuscula, lutescenti-alba, atrofusco fasciata, undique subtilissime reticulata ; epidermide tenui, lutescente; spira exserta, parviuscula,subacuta; anfractibus convexis ; apertura ampliuscula ; columella callosa, fusco sufusa ; labio externo subincrassato, vix reflexo; long. 70, lat. 60 ; apert. long. 50, lat. 35 mill. Shell rather globose, imperforate, rather solid, yellowish white, banded with dark brown, throughout very finely reticulated; epidermis thin, yellowish ; spire rather small, exserted; whorls convex ; aperture rather wide; columella thickened, suffused with brown ; outer lip somewhat thickened, scarcely reflexed. Hab. Catamarca (on the Andes of Peru). A fine species of the type represented by A. columellaris. EXPLANATION OF PLATE LXXII. Fig. 1,1a. Ovulum sinense. Fig. 3, 3 a. Strombus robustus. ' 2,2 a.
