discussion
Remarks. The material obtained from the Mauritanian cold-water coral mound barrier was consistent with those described by Ramil & Vervoort (1992) and Ansín Agís et al. (2001) from Azores and Northwest Africa.
distribution
Distribution. An East Atlantic species distributed from Iceland and Norway to off the mouth of the Congo River and in the Alboran Sea, West Mediterranean (Ansín Agís et al. 2001). In West Africa, it was collected from Morocco (Kramp 1947; Patriti 1970; Ramil & Vervoort 1992), Mauritania (Gil & Ramil 2017 a) and off the mouth of the Congo River (Vervoort 1966). Its bathymetric range extends from 47 to 2200 m (Ansín Agís et al. 2001). Our material was collected on the cold-water coral mound barrier from depths of 405 to 561 m.
