Aulus japonicus, Dunker, Proc. Zool. Soc. 1861, p. 426. Cultellus , Sowerby, Conch. Icon. pi. v. f. 15 6 (non 15a). Machcera japonica, Clessin, Conch.-Cab. p. 63, pi. 18. f. 5. Hab. Japan. The shell figured by Sowerby (fig. 15 a) is in the Cumingian collection labelled "pulchra, Gould," and not "pulchra, Dunker," as stated in his synonymy. It seems to m e different from S. japonica, for although the colouring is very similar in both species, S. pulchra has the umbones more excentric and has not the keel-like ridge which defines the dorsal area in S. japonica. " S. pulchra, Gould," is given in Conrad's Catalogue of Solenidse 1 without any reference, nor have I been able to discover where it was described. 229. TUGONIA NOBILIS, A. Adams. Hab. Assab, Kamaran (Caramagna). This species is very like the West-African T. anatina, and seems distinguished merely by the absence of radiating striae anteriorly. It is very variable in form, some specimens being much more globular than others. " West Africa," assigned to this species in the ' Conchologia Iconica,' may not be incorrect, although we scarcely expect to find the same species at Senegal and Aden. T. semisulcata, A. Ad., I regard as the young of this species, and T. siphonata, Reeve, and T. compressa, Reeve, are likewise young specimens of T. anatina, Gmelin. 230. VENERICORDIA ANTIQUATA (Linn.). Hab. Ceylon. 231. VENERICORDIA CUMINGII, Deshayes. Hab. Borneo. This species, described in the Proc. Zool. Soc. 1852 (p. 102, pi. 17. f. 15), is not so pointed posteriorly as the preceding. In other respects it is very similar, and it is probable that the two forms pass one into the other. V. canaliculata, Reeve, appears to be another form of the same species. 232. CARDITA (BEGUINA) GUBERNACULUM, Reeve. Hab. Zanzibar, Madagascar. 233. LUCINA (CODAKIA) EXASPERATA, Reeve. Dab. Honduras (Reeve). New Caledonia, N. Australia, Ami-rantes Islands, and Red Sea (Brit. Mus.). The Caribbean locality has not yet been confirmed, but it is quite possible it may be correct, for another well-known species of this 1 Arner. Journ. Conch, vol. iii., Appendix, p. 23. PROC.
