Remarks. This species has been found in all the facies identified in the sampled area but it is not abundant ( Table 1, Figure 2 ). M. adriatica has been reported from the Pleistocene of the Mediterranean and Aegean areas but it seems to be extinct in the Recent Mediterranean. Interestingly, Breman (1975) found M. adriatica in levels dated to the Upper Pleistocene including the AllerØd and Younger Dryas climatic stage (cores 353 in the Adriatic Sea), and considered this species as a cold water indicator.
