BATHYMETRIC DISTRIBUTION. — Recorded depth in Guadeloupe: 0-150 m (live specimens at 3-23 m); some intact adult shells obtained by KARUBENTHOS 2 between 204-482 m, but they must be regarded with caution. Recorded depth in Martinique: 0-80 m (live specimens at 4-70 m). Previous recorded depth in the West Atlantic: 0-160 m, with discrepant records down to 480 m ( Fernandes & Pimenta 2020).
