Description

Shell—High, narrow, fusiform, subscalar, bicarinated, tubercled, fulvous, with brown specks between the carinal tubercles. Sculpture: Longitudinals: there are rough lines of growth. Spirals—the whole surface is covered with very unequal threads; immediately below the suture is a broadish thread, puckered by the lines of growth; below this on the shoulder of the shell there are 3 feeble threads rather widely and quite shallowly parted; the corner of the shoulder has a strongish rounded keel cut into white blunt tubercles, between which are chestnut spots ; below this keel is a broad and somewhat constricted furrow in which are some (3 to 6) feeble threads ; the lower. Bide of the furrow is formed by another keel also tubercled and speckled, but weaker than the upper keel. Between these two keels the shell Is cylindrical; from this point it begins to contract, has one feeble thread, then plainly within the base 2 strongish threads, which are subtubercled; below this on the front of the b(ase and on the pillar are about 10 threads; the point of the pillar has no threads, but is very rough. Colour fulvous, with whitish aud chestnut specks; the point of the snout is white. Spire high, narrow, conical, slopingly scalar. Apex coronated (?); it is somewhat rubbed, but seems to consist of 3 to 4 whorls. Whorls 7, exclusive of those of the apex; they are bicarinated, constricted above and below, of slow and regular increase; the last is small, with a rounded elongated base and a small somewhat longish snout. Suture strongly marked by the constriction above it, and marginated by the puckered thread below. Mouth club-shaped. Outer lip thin, with a sinus strong rather than deep, V-shaped, extending from the suture, and having its apex at the keel. Inner lip thin, concave above, then direct, and then at the canal strongly cut off to the left, and having a slight twist on its edge. H. 0,92 in. B. 0,3. Penultimate whorl, height 0,14. Mouth, height 0,44, breadth 0,16.
