Show 338 MR. E. A. SMITH ON THE [Apr. 1 general colour of the shell appears to be brown or reddish, but on close examination it will be seen that the spiral striae are whitish, and the interstices or lirae only are coloured. PLEUROTOMA (MANGILIA) CASTA, Reeve. The single shell collected by Capt. Turton agrees in many respects with the type of this species, which, unfortunately, is in rather bad condition, and only exhibits faint indications of spiral stria?. The specimen from the " Sea-horn " is beautifully striated, is rather shorter, and has one costa less than the type. Nevertheless, I have a strong belief that it belongs to the same species. The locality of P. casta was unknown to Reeve. MUREX (OCINEBRA) PURPUROIDES, Dunker. Hab. Cape of Good Hope. COLUMBELLA (ANACHIS) KRAUSSII, Sowerby. Columbella kraussii, Sowerby (1844), Thesaurus, Conch, vol. p. 144, pi. xl. figs. 180, 181 ; Reeve, Conch. Icon. fig. 213. Buccinum cereale (Menke, MS.), Krauss (1848), Siidafr. Moll. p. 122, pi. vi. fig. 17; Reeve, Conch. Icon. (Columbella), pi. xxi. fig. 118. Columbella (Anachis)fulminea, Gould, Proc. Bost. Soc. Nat. Hist. vol. vii. p. 334; Otia, p. 131. This seems to be rather a common shell on the South-African coast. C. fulminea was described from Simon's Bay, Krauss cites the Cape Coast for it, and in the Museum there is a series labelled Natal. Two specimens only, of a rather dark tint, were obtained at St. Helena. COLUMBELLA (MITRELLA) PROSCRIPTA. (Plate XXIV. fig. 12.) Testa minuta, angusta, tenuis, nitida, pallide fuscescens, infra linea saturatiore cincta, versus apicem dilute rosacea; anfractus 5, primi duo magni, laves, convexi, cceteri convexiusculi, striis paucis spiralibus pallidis (in anfr. ultimo circiter 12) sculpti ; apertura angusta, longit. totius £ vix cequans leviter incrassatum, superne subsinuatum, ad marginem fusco tinctum ; columella rectiuscula, callo tenui induta. Longit. 4 millim., diam. 1|. A small shining pinkish-brown shell, exhibiting a few spiral pale striae. The penultimate and antepenultimate volutions show indications of longitudinal plication. PURPURA SQUAMOSA, Lamarck. Hab. Cape of Good Hope and Natal coast (Krauss and others); St. Vincent, Cape Verde Islands (Dunker). Only one young specimen of this common South-African species was sent by Capt. Turton. The locality given by Reeve (Con. Icon. sp. 48), " Tigre Bay, Abyssinia," requires confirmation. It may be correct, but the number of species common to South Africa and the Red Sea is not large. |
