Aphorais Gracilis

  • Aphorais gracilis Aldrich, 1886

Original Description of Aphorais gracilis by Aldrich, 1886, p. 32:

  • "Shell fusiform, whorls eight, spire high; embryonic whorls smooth, the others to the body whorl with longitudinal ribs which curve to the left into the suture and are crossed by fine revolving lines; body whorl expanded into a broad outer lip, furnished with two digitations, the posterior one the largest, rising in some specimens into a long, sharp point, strongly grooved to the apex. The outer lip extends up the spire to the top of the body whorl only; the groove in the anterior digitation rather faint; surface of body whorl with two revolving carina marking these grooves and covered with faint revolving lines; aperture small, inner lip with a spreading callus; canal moderate, terminating in a sharp point slightly recurved."

Comment: The name might be a junior synonym of Aporrhais gracilis von Koenen, 1885
