MRC. Remarks. This species was figured by both Norman & Stebbing (1886) and Lang (1955, 1968), although neither gave a figure of the habitus from dorsal view (see Fig. 5) (Lang 1955, included a photograph). Apseudes grossimanus , with its characteristic tridentate rostrum, is the only apseudomorphan species recorded previously from deep-sea chemosynthetic habitats, on the Mid-Atlantic Ridge (Larsen et al. 2006); it is otherwise widespread in the north-east Atlantic, to which distribution the present records add nothing new. Records of A. grossimanus from off South Africa and in the Mediterranean (see Sieg 1983) must be regarded with some suspicion. Neither this species nor A. setiferus (see above) shows any particular morphological adaptation to the conditions found at chemosynthetic habitats.
