52J» Miscellaneous* This very beautiful species is very closely allied to a shell in Mr. Cuming*s collection, which has been attributed by Mr. Sowerby, in his * Concholoj^ical Illustrations,' to M. triffonulus, Lamarck. It is also as closely allied to a shell in the collection of the King of Denmark, wliich was figured for that species by myself in the * Con-cbologia Iconica.' From both, however, it is sufficiently distinct to establish its claim to rank as a new species. C. Cyclostoma TtJBULUM. Ci/cl. festa impe7'forata, turbinata ; spira elecatiuscula ; anfractibus roUmdatiSy Icevihus ; apertura circulari ; Jabro eleganter expanso ; lutescente-alba, nigricanti' fusco rnultifasciata, Lat. \\ poll. Hab, ? This very elegant species partakes of the characters of C. Belairi and Boivini, but is quite distinct from either of those species. There is no umbilicus and very little umbilical callosity. The bands are peculiar in extending over the expanded Itp to the extreme edge. 7. Cyclostoma Eugenije. Cycl. testa subprofunde umbilicata, subdepresso-orbiculari ; spira brevi ; anfractibus ad suturam leviter impressis, deinde convexisy spiraliter dense elevato-striatis, in medio acute tenuicarinatis ; apertura circulariy labro {in hoc specimine) simplici ; fulvescetite-spadiceay infra castaneo plus minus tenue vittata. Lat. 1 poll. Hab. Mauritius (found in the heights of Flacq, at the roots of a Bois-de-Natte tree). Most nearly allied to C.Jilosumy but of lighter texture and warmer colour. MISCELLANEOUS. British Edriophthalma. To the Editors of the Annals of Natural History. Plymouth, Dee. 16, 1857. Gentlemen, — Further opportunities and more extended investi-gations compel me to make the following corrections in the Synopsis of the British Edriophthalma recently pubHshed in the Annals : — 1. Instead of adopting Dana's arrangement of the genus Orchestia, and making Talitrus a subgenus, it will be more in accordance with our present knowledge to divide Talitrus itself into two genera, as has been done by Nicolet and Stimpson, and thus adopt the genus Orchestoidea of the former (Gay's 'Chih'), which is synonymous with Megalorchestia of the latter (Proc. Nat. Hist. Society Boston, * Crust. &c. Pacific Shores of North America').
