Material examined. BIOICE stn. 2859, RV Bjarni Saemundsson, RP sled, 29 August 1995, 61°5022N, 16°5286W, 2270 m, 2.37°C, 39 specimens (IMNH 37022); BIOICE stn. 2860, RV Bjarni Saemundsson, RP sled, 30 August 1995, 61°4343N, 16°5748W, 2295 m, 2.60°C, 57 specimens (IMNH 37023).

Remarks. Hansen (1916) described H. spinifer from specimens collected at depths of 1505–3474 m in the Labrador basin and at the eastern margin of the deep Reykjanes Ridge. Here, the species was only found at two deep stations south of the Ridge in the Iceland basin ( Fig. 11 C). Lincoln (1985b) did not report the species from the Rockall Trough or the Porcupine Sea-Bight. The species has a very wide distribution and has been reported in the South Atlantic Ocean ( Brökeland & Wägele 2004) and in even in the Southern Ocean (see Meyer-Löbbecke et al. 2014), and has been suggested to be a potential species complex.
