Remarks. This species has been detected in almost all the facies sampled in the SML CWC. E. echinata seems to be absent from the Recent Mediterranean but it has been reported from layers deposited during the cold phases of the Pleistocene ( Breman, 1975; Peypouchet and Nachite, 1984; Moncharmont-Zei et al., 1985). According to Barra and Bonaduce (2000), this species can be considered as a cold water indicator.
