Bolma bathyraphis is a species of sea snail, a marine gastropod mollusk in the family Turbinidae, the turban snails.[1][2]
The size of the shell attains 35 mm. The imperforate shell has a turbinate shape with a conical spire, nine whorls and deeply, broadly canaliculate sutures. The spire is marked by a row of granules. The white apex is obtuse and plane. The periphery is formed of a squamose keel which is spirally irregularly striated. it ascends the spire above the sutural furrow, and between it and the suture there is a series of very small white granules. Of the row of granules upon the lower half of the body whorl, the third from the periphery is a little larger than the first and second and much larger than those below. Both above and below this third row a few spiral elevated lines are noticeable. The aperture, has an irregular rounded shape. Although quite smooth within, it has the appearance of being sulcated, the pseudo-sulci corresponding to the rows of granules.[3]
