Descrição original:
(Pilsbry, 1930): “The ovate shell is decidedly more ventricose than 0. puilehella prototypus, with shorter spire and larger aperture; rather thin. Ground color dull white, with some of the very thin, glossy pale buff periostracum remaining on the last half of the last whorl; the vinaceous-slate streaks are intensified and spread to form spots at the positions of the three bands. Apex marked with a blackish-brown spot.
Most adult specimens show one narrow dark varix-streak in front and two or three on the back. The surface shows microscopic spiral striae, close, irregular and waved, where the periostracum is preserved. The aperture is large, about 65 percent of the length of the shell, strongly oblique, the lip with blackish-brown border. Columella whitish, slightly curved. The parietal wall has a weak wash of chestnut color.”
