Shell broadish, conical, sharply keeled, strong, porcellanous, with a shortish contracted base, a short snout, short narrow ribs, spiral threads, and a bulbous apex. Sculpture: Longitudinals: below the sinus-area and about one-third down the whorl from the suture arise, not quite abruptly, ribs slightly tubercled at the top, straight, direct, narrow, and parted by shallow furrows about twice their breadth; they become feeble toward the lower suture; on the last whorl they do not continue to the base, and become broader and weaker toward the mouth : there are eleven on the last and penulti¬mate whorls; on the first infra-embryonic whorl there are about seventeen, crowded, sharp, scarcely curved and oblique. The lines of growth are numerous and unequal; in the sinus-area they are sharp and delicate, on the rest of the shell coarse and puckered. Spirals: marginating the suture at the top of each whorl is a narrow scarcely swollen band; below this the sinus-area is very finely, almost microscopically, scratched; and this scratch-sculpture is continued, though less distinctly, on the rest of the surface. The projection of the top of the ribs forms a sharp keel; The rib-area is crossed by five coarsish threads, which rise into small tubercles on the ribs; one or two smaller threads come in between the lines of these spirals. The same sort of threads, but less distinct, are found on the base; those on the pillar and snout are a little more distinct. Colour dull porcellanous white. Epidermis quite gone. Spire rather short, conical, very slightly scalar, cylindrical toward the top. Apex two smooth embryonic whorls, swollen and roundedly pressed down, with a deepish suture, rather more prominent than the regular whorl which follows. Whorls 6,5 , short, of rather rapid increase; the last large relatively to the rest; from the suture to the ribbing they are concavely shouldered. The projection of the tubercles at the top of the ribs forms a carination, which does not really exist in the form of the whorls themselves; there is a very slight contraction towards the lower suture. The last whorl contracts slightly from the keel to the edge of the base, and from that point rapidly to the small, narrow, straight, and direct snout. Suture coarse, slightly impressed, and well defined by the band below it. Mouth narrowly oval, pointed above, with an oblique, short, rather .open and gradually contracted canal in front. Outer lip a rather depressed convex curve, a little concave at the top and flattened toward the, point: on leaving the body it retreats at once, forming a shallow, blunt V-shaped sinus, from the lower side of which, with little of angulation, it advances very straight to the edge of the canal, whence it slowly curves backward round the open point of the snout. Inner lip spreads as a very narrow porcellanous glaze; it runs very obliquely to the base of the shortish narrow pillar, below which point it is a very little hollowed. The point of the pillar is cut off with a very slight obliquity, and has a blunt and very slightly twisted edge. Operculum small, oval, smooth, with hair-like striae, apex terminal, colour pale brownish yellow. H. 0.5 inch. B. 0.23 inch. Penultimate whorl, height 0.1 inch. Mouth, height 0.24 inch, breadth 0.12 inch.
