Bolma myrica: Shell turbinid, roundly conical. Protoconch pinkish in color, almost planispiral, carinate. Teleoconch pinkish brown in ground color with spiral cords bearing white granules. Eight cords on penultimate whorl, among which subsutural one is strongest and following two are second strongest of all. Peripheral cord (second one above suture of subsequent whorl) also somewhat strong and even spinous on early teleoconch whorls. Basal periphery round. Base rather flat, ornamented by regularly granulate spiral cords in same fashion as lateral surface. Umbilicus closed by thick, pale pinkish callus. Aperture slightly oblique, nacreous within. Outer lip not thickened nor reflexed. Columellar lip curved with thick callus bearing a low node near base. Operculum calcareous, weakly granulated externally.
Shell height 12.5 mm, shell breadth 11.3 mm.

Bolma myrica: Only a single specimen has been available for study. This is a typical Bolma of small size. The ornamentation of white granules on the surface and base is very distinctive. There is a sign of row of spines on the periphery of very early teleoconch whorls, but no such sculpture remains on later whorls. A similar-looking Bolma, though larger in size, may be B. tayloriana (Smith, 1880), which has less compactly arrranged granules that are not whitened. A young specimen illustrated by Beu & Ponder (1979) has sharp basal periphery unlike the present new species.

Bolma myrica: Collected from bathyal depths and seamount in Japanese waters.
