Remarks. Previously Antennuloniscus simplex was known only from the type locality in the Rockall Trough at 1900 m ( Lincoln 1985b). During the BIOICE project it was sampled mainly at several neighbouring stations in the Iceland basin and at two station in the Irmiger Basin, south of the Iceland-Faeroe Ridge at depths between 1558 and 2295 m ( Fig. 12 A, Table 1), extending the known distribution of the species to about 63°N.
