(3 empty shells, in 2 samples): SPAIN • 2 sh; 42° 30.391′ N , 009° 19.517′ W to 42° 29.428′ N , 009° 17.924′ W ; 147–148 m ; 17–28 SeP. 2004 ; VERTIDOS AG-EBS-150 • 1 sh; 44° 11.652′ N , 008° 58.152′ W to 44° 11.539′ N , 008° 57.574′ W ; 908–1106 m ; 15–24 Jul. 2008 ; A SELVA DRN-7 . Remarks. As in the previous species, Manzonia crassa is very common in sublittoral bottoms from the British Islands to Morocco (not present on the Macaronesian islands) and throughout the Mediterranean ( Gofas & Oliver, 2011 ). Three eroded shells ( Fig. 21g ) have been found in two of the samples likely swept by the currents away from the coast.
