Diagnostic characters
Shell tall, narrow, distinctly cyrtoconoid, semitransparent, with flattened, blunt apex; suture between penult and last whorl very deep, often cutting into shell profile closer to shell axis than that between antepenult and penult whorls. Without costae and usually also without apparent spiral ridges. Posterior end of foot cleft medially.
Other characters
The sides of the basal half of the shell are nearly parallel (discounting the curvature of the whorls), but bend to the rather blunt apex. If any spiral ridges occur they are extremely weakly developed. The yellow colour resides in the periostracum, the shell below being white. Up to 3 mm high, 1.5 mm broad; last whorl occupies 60% of shell height, aperture 35%.
H. vitrea is distributed from the Mediterranean north to Norway but is recently recorded only from a few Scottish and western Irish localities where it may be locally not uncommon. It lives on muddy-sandy bottoms from 10 to 50 m deep.

England, Norwegen bis Smyrna und Schwarzmeer. Nördlich 5—10 in tief, südlich tiefer (bis 120 m) auf Schlamm.
