| Summary: | Toledonia cf. elata Thiele, 1912 Fig. 5L 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. : Published as part of Luca, Javier Di & Zelaya, Diego G., 2019, Gastropods from the Burdwood Bank (southwestern Atlantic): an overview of species diversity, pp. 41-78 in Zootaxa 4544 (1) on pages 66-67, DOI: 10.11646/zootaxa.4544.1.2, http://zenodo.org/record/2618137 : {"references": ["Thiele, J.
