Scaliola gracilis A. Adams, 1862b. Length, 3 mm; diameter, 2 mm. Shell: conical; with convex whorls sparsely agglutinated with sand grains; white. Spire: protoconch of three whorls, the apical smooth, the next with axial threads, the third unicarinate; teleoconch of five convex whorls; suture deeply impressed. Sculpture: faint axial striae; whorls sparsely covered with sand grains. Aperture: circular; outer lip thin; last whorl somewhat separated from the penultimate whorl. Color: white. These shells are found in sediments at depths of from 3 to 60 m. They are less common than are the shells of S. bella and S. glareosa.
S. gracilis was described from Japan. The shells are distinguished from those of the other two species by the lesser numbers of sand grains and partially detached last whorl.
