Remarks. The only previous record of Haploniscus aduncus was from the type locality in the Iceland Basin (60°7.1´– 60°8.3’N, 19°30.3´– 19°24.8´W, 2636–2646 m, Lincoln 1985b). The new records of H. aduncus were in the Iceland Basin, to the west and the north of the type locality, and additionally from the Irmiger Basin, at depths between 1543 and 2537 m ( Table 1, Fig. 10 B).
