''Turridrupa bijubata'', common name the crested turrid, is a species of sea snail, a marine gastropod mollusk in the family Clavatulidae. ==Description== The size of an adult shell varies between 11 mm and 25 mm. The color of the shell is chocolate-brown, encircled by narrow, lighter-colored keels The second keel, which is somewhat stronger than the others, is often broken up into small tubercles. The interior of the aperture is chocolate-colored. The siphonal canal is short. It is distinguished from ''Turridrupa cincta'' (Lamarck, 1822) by its narrower form, a longer spire, sharper ridges and a darker color.〔George Washington Tryon, Manual of Conchology vol. VI p. 241; 1884 (described as ''Surcula bijubata'')〕
