Pleurotoma megalembryon Dautzenberg & H. Fischer, 1896: 420, pl. 17 fig. 14.

MATERIAL EXAMINED. — 8 sh., DW130.
REMARKS
Apart from being slightly larger, we cannot see any speciesspecific difference between the syntype of Teretia strongyla figured by Horro & Rolán (2017: 147), the Azorean type specimen of Pleurotomella megalembryon figured by Dautzenberg & H. Fischer (1896) and our material and therefore consider these as synonyms. This is therefore another amphiatlantic species, recorded from off Georgia ( Dall 1927), the Azores ( Dautzenberg & Fischer 1896) and the northern part of Bay of Biscay ( Bouchet & Warén 1980), and new to Spanish waters.
