[Reprinted from the Journal of Conchology). JOURNAL OF CONCHOLOGY, on MARINE SHELLS OF SOUTH AFRICA. By G B. SOWERBY, F.Ls:, F°Z.S: (Read before the Conchological Society, November 3rd, 1893). Tue following species have been brought to my notice since the publication of my work with the above title in 1892. The references are not always to original descriptions, but to figures in well-known works. Murex ramosus Linn.—Sow., ‘Thes. Conch.,’ vol. -iv., pl. 387, fig. 69. Natal. Tritonidea subrubiginosa, — Smith, ‘Proc. Zool. Soc.,’ 1879, p. 200, pl. 20, fig. 40. Natal (Burnup). Pleurotoma cingulifera Lamk.—Reeve, ‘Conch. Icon.,’ vol. 1., Plewrotoma, fig. 1. A young shell from Knysna. Mangilia cerea (?) Carpenter.—A small shell bearing a very close resemblance to this species has been submitted to me by Langley Kitching, Esq, from near Cape ‘Town. Triton gemmatus.—Reeve, ‘Conch, Icon.,’ vol. ii., Z7/on, pl. 15, fig. 60. Natal. Triton tuberosus Iamk.—Reeve, ‘Conch. Icon.,’ vol. ii, Triton, pl. 1, fig. 1. Natal. Triton gallinago,—Reeve, ‘Conch.

Testa acuminata, solidiuscula, luteo-albida; spira acute turstta, ad apicem obtusiuscula ; anfractus 6 primt (2) laves, sequentes granulatt, spivaliter sulcatt, longitudinaliter plicati, sulura 6 SOWERLY : MARINE SHELLS OF SOUTH AFRICA. anguste canaliculata divisi ; anfractus ultimus spiram paulo superans, leviter inflatus ; apertura latiuscula ; columella leviter tncurva, callosa. Long. 19, diam. maj. 9 millim. Fab. Natal, Durban. A very distinct species which may be at once recog- nized by its granular sculpture. Oliva ispidula Linn.—Sowb., ‘Thes. Conch.,’ vol. iv., p. 21, pl. 343, fig. 248. Fasciolaria trapezium Linn.—Sowb., ‘Thes. Conch.,’ vol. v., pl. 426, fig. 22. Natal. Latirus abnormis Sowerby, n. sp. Testa elongato-fusiformis, crassa, utringue acuminata, umbilt- cata, castanea ; spira turrita, acuta, sutura trregularts ; anfractus 6-7, leviter convext, nodts conspicuis rotundatis armati , spiraliter sub-obsolete livati ; anfractus ultimus superne leviter concavus, obtuse bt-angulatus, ad angulum superum valde nodosus, ad angulum inferum nodts levigatis munitus, inferne leviter concavus, in cauda breviuscula de- sinens ; apertura oblonga ; columella rectiuscula, albo-callosa, glabra, haud plicata ; canalis latiusculus, medtocriter longus. Long. 57, diam. maj. 23 millim. Hab. Natal. This species, though evidently a Zatirus, shows no signs of the columellar folds supposed to be characteristic of that genus. In this respect, however, it does not stand alone, the same being observed with regard to Z. gidbudlus Gmel., and the species from the Cape de Verde Islands, to which I recently gave the name of Z. maxtmus (‘The Con- chologist,’ 1893, vol. ii., p. 139, pl. 1, fig. 5). Voluta festiva I.amk.—Sowb., ‘Thes. Conch.,’ vol. i., pl. 52, figs. 79, 80. A young specimen of this rare species was recently found on the Natal coast by Mrs. Trotter. Mitra literata Lamk.—Sowb., ‘Thes. Conch.,’ vol. iv., pl. 372, fig. 436. Natal. Mitra limbifera Lamk.—Sowb., ‘Thes. Conch.,’ vol. iv., pl. 366, fig. 261. Natal. J.C., yit., \pril 1894. SOWERBY: MARINE SHELLS OF SOUTH AFRICA. 7 Marginella rufula Gaskoin (MSS.).—Reeve, ‘Conch. Icon.,’ sp. 149. Green Point, Cape of Good Hope. Marginella perminima Sowerby, n. sp. Testa minuta, oblongo-ovalis, albida, postice rotundata, antice leviter attenuata; spira immersa, apertura angusta ; columella triplicata ; labrum crasstusculum. Long. Th, lat. } millim. Fab. South Africa (Captain Turton). A minute species with immersed spire, allied to JZ mintma Guilding, but more cylindrical in form. Columbella kitchingi Sowerby, n. sp. Testa breviuscula, crassa, imperforata, albida, fusco-bifasciata ; spira aculiuscula ; anfractus 5, convext, sutura anguste canaliculata sejunctt, longttudinaliter costati, costis circ. 8, rotundatis ; anfractus ultimus leviter inflatus, infra medium contractus ; apertura auriformis ; labrum arcuatum, intus valde quadriplicatum ; columella rectiuscula, levts. Long. 6, maj. diam. 3 millim. Hab. Green Point, Cape of Good Hope. This species somewhat resembles C. cereadrs, but it has plain-brown bands in place of the zig-zag markings, and is notably distinguished by the dentiform plice in the mouth. The type-specimen was found in the above locality by Langley Kitching, Esq., after whom I have pleasure in naming it. There are also specimens in the British Museum. Columbella (Mitrella) pyramidalis Sowerby, n. sp. Testa angusta, crasstuscula, levts, lutea, fusco sparsim strigata ; spira elongata, acuta; anfractus 8, plant, levis, sutura linearts ; anfractus ultimus infra medium obtuse angulatus ; apertura latiuscula, utringue attenuata ; columella incurva, truncata ; canalis brevissimus.

Long. 7, maj. diam. 8 millin. Tab, Natal. A small species somewhat resembling JV. zmperforata, but distinctly perforate. It differs in form from JV. foraza, and the umbilicus is smaller. Natica sebz.—Souleyet, ‘Voyage de la Bonite,’ pl. 35, figs. 6, 7; ‘Thes. Conch.,’ vol. v., pl. 457, fig. 79. Natal. Natica teeniata Menke=N. ala-papilionis Chemn. “Thes.
