Addenda to the conoidean gastropods of the outer continental shelf and slope off Galicia (NW Iberian Peninsula)

Four species of conoidean gastropods (Gymnobela lamyi, Phymorhynchus chevreuxi, Theta chariessa and Xantodaphne cf. dalmasi) are added to those recorded in a previous work on circalittoral and bathyal bottoms off the Galician continental margin. Data on three other previously mentioned species (Typhlomangelia nivalis, Austrobela pyrrhogramma and Gymnobela abyssorum) found in the same sample are also added.
