Toledonia elata Thiele, 1912: 249, pl. 14, fig. 22
Examined material. 1 an. and 7 sh. (MACN-In 40708). Description. Shell height to 2.3 mm (up to 3.5 mm according to Dell 1990); elongate-ovate, delicate.
Protoconch smooth, of 1.5 slightly convex whorls. Teleoconch of up to 2 whorls, slightly convex in outline; last whorl comprising about 85% of total shell height. Suture deep, slightly channeled. Surface white; only sculptured with faint growth lines. Aperture ovate, wider anteriorly than posteriorly; interior white; columella with a strong fold; callus narrow, slightly expanded over the umbilical area.
Remarks. In shell morphology the material here examined closely resembles Toledonia elata, from which however it differs by having a straight (instead of angulated) columella.
