Conch, fig. 600 (vile!). Hab. Station 5. Island of Luzon (Cuming). A single specimen (fig. 53a), which I consider a variety of this species, differs from the type (fig. 53) in being nearly black, with the white zone less well defined, but marked in the same manner with short black and brown lines upon the ribs. Reeve does not mention the sculpture between the costae : it consists of well impressed lines or sulci, six in number on the upper whorls and eleven or twelve on the last, besides some strong oblique grooves at the extreme base ; the lira? between the latter, of which one is especially prominent, are spotted with white. The figure in the Con. Icon, represents the spire much too turreted and the whorls too flat. The copy of Reeve's figure in Sowerby's Thesaurus is simply as bad as possible. 86. CANCELLARIA JAPONICA. (Plate XX. fig. 54.) Shell ovate, pyramidal, white, thickish: whorls 7, convex, divided by a deep suture, longitudinally ribbed and spirally Urate ; costae rounded, oblique, about 13 on a whorl, rather broader than the interstices; transverse lira? prominent, six or seven on the penultimate whorl and twelve on tbe last: aperture small, occupying about three eighths of the entire length ; columella with two small central oblique plaits. Length 12 millims., diam. 5. Hab. Station 1. This species is remarkable on account of its elongated form and the absence of colour. The only specimen is not in very good condition, and the lira?, which are usually met with in the aperture of species of Cancellaria, are not present, and possibly have been broken away with the front part of the labrum, which is incomplete. 87.

These three species are very closely related; and it is somewhat doubtful if they are really distinct. If they prove to be so, the name fulgurata will take precedence of the other two by many years. This species was quoted by m e in the 'Annals and Magazine of Natural History ' under the name of O.fulgurata. 88. OLIVA (OLIVELLA) SPRETA, Gould. (Plate XX. fig. 55.)
