REMARKS

The specimens from both stations have shells similar to that described by Hoek (1883: 143) with the carina very convex ( Fig. 28 ). Altiverruca obliqua was redescribed and discussed by Young (1998b: 46). It was first described from off Southwestern Spain ( Hoek 1883) and subsequently recorded from the Azores region ( Young 1998b, c) from depths between 1003 to 2788 m. These new records agree with the previous distribution. They were collected south of the Azores Archipelago at depths of 945 and 1000 m.
