Spathoderma grossum Scheltema & Ivanov, 2000

Scheltema & Ivanov, 2000: 359.

( Figures 25 , 26 ; Tables 4a, 5)

Additional material examined: Guiana Basin , 5 specimens ( Table 4a); Argentine Basin, 66 specimens ( Table 5); 1 new record, from West European Basin, 50º27.3'N, 13º20.9'W, 2,506 m ( RV Chain cruise 106, stn 318, 19.08.1972) .

Distribution: Amphi-Atlantic: Eastern Atlantic from the West European Basin to the Cape Basin at abyssal depths> 4,000 m ( Scheltema & Ivanov, 2000), except shallower in the northern West European Basin; Western Atlantic from the Guiana Basin on the continental rise at 3,859 m to the abyss at 4,980 m, and not reaching the abyss in the Argentine Basin, 2,440 –3,906 m ( Figs 25 , 26 ).

Remarks: The new records indicate that S. grossum , as a primarily abyssal or lower continental rise species, occurs on both sides of the Atlantic south of 13°N, but extends further north to 50°N in the eastern Atlantic.
