Nuculana fossa was well distributed over the outer )rtion of the southeastern shelf and part of the outer shelf (Figs. 66-1, 66-2, and 66-10). The greatest abundance of this species occurred at Stations 18, 28, 29, 36, 47, 49, 64, 65, 70, 71, and 72 (Figs. 66-2 and 66-11; Table 66-4). It was present at 36 percent of the stations sampled by van Veen grab. The greatest biomass occurred at Stations 29, 47, 64, and 71 (Table 66-4). Nuculana fossa was associated v^rith sediment types ranging from fine sand to medium silt (; Tables 66-1 and 66-2, Figs. 66-2 to 66-6, 66-10, and 66-11, Table 66-5). Major Component of Collection: Eighty-four percent of A'^. fossa occurred in very fine sand to medium silt () with 96 percent of the clams at sediment sorting values from
