Sculpture: the whole surface is very harshly roughened by a network of coarse, sharp, narrow, unequal projecting bars, which give a crusted appearance to the shell, where this network is rubbed off the surface of the shell appears like frosted glass fretted in squares: the longitudinal bars run on the lines of growth, those which cross them are spirals. Colour: the surface made up of the bars is dead dirty white. Spire: a little sunken, in the bottom of a small, open, funnel-shaped depression is the mammillary apex, round which coil two whorls. Suture barely impressed. Mouth pear - shaped, rather small. Outer lip rises shortly, makes a short and narrow curve at the top, runs down with a hardly prominent edge and but slight curve to the base, where it sweeps round freely (but is barely patulous) to join the point of the pillar. Inner lip: down the body from well inside the month this lip projects as a narrow square-set shelf, which dies off on the straight longish sharp-edged pillar, which is slightly truncate at its point - L. 011. B. 007.Of this curiously marked Philine I got only two specimens, one of them young - both from about 50 fms.
