TYPE MATERIAL. Five syntypes: NHM-G26359, NHM-G26360 NHM-G26361, NHM-G26362, NHM-G26363 (Santa Cruz).
REMARKS. Sowerby mentioned also San Julián as a locality for this species (the figured specimen is presumably from Santa Cruz), but it remains unclear from what horizon it comes. South American turritellids are badly in need of revision, so the generic placement – while certainly not Turritella s.s. – must remain uncertain at present. The other species described by Sowerby from Chile, Turritella suturalis (= T. pseudosuturalis d’Orbigny, 1852), seems to be distinct.
