“EUTHRIA MERIDIONALIS, sp. n. (Plate IV. fig. 6.)
Shell fusiformly ovate, small, brown, pale at the apex. Whorls 6; apical one smooth, whitish, convex; the rest only slightly convex, longitudinally costate, and transversely sulcate. Suture scarcely oblique, rather deep. Costæ a little slanting, somewhat arcuate, about 14 on the last whorl, which do not attain quite to the employed lower extremity. Sulci narrow, rather deep, cutting through the costæ, not nearly as broad as the interstices, 4 to 5 in number on the upper whorls, and about 18 on the last, whereof those around the extremity are finest and closest together. Aperture elongate-ovate, producedbeneath into a short, oblique, recurved canal, and equally about two fifths of the whole length of the shell. Labrum simple, thickened exteriorly by the last rib. Columella covered with a thin, smooth, whitish callosity, arcuate at the middle. Length 9 millims., diam. 3⅓, aperture nearly 4 long and 1⅔ broad.
Hab. Stations 5 and 7.
There are but two examples of this little species, one not quite mature, and the other at some time inhabited by a Paguroid crustacean. The latter circumstance may to some extent have caused the absorption of any liræ or denticles within the labrum, if such ever existed. The first sulcus beneath the suture cuts off the tops of the costæ, which consequently present the appearance of squarish nodules.”
