Yoldia amygdalea was present on the central and northwestern portions of the southeastern shelf and north and south on the central shelf (Figs. 66-1, 66-12, and 66-13). The greatest abundance of this species occurred at Stations 63, 64, 70, 70A, 71, and 72 (Figs. 66-12 and 66-13; Table 66-4). It was present at 23 percent of the stations sampled by van Veen grab. The greatest biomass occurred at Sta- tions 63, 64, 70, 71, 72, 82, 83, and 937 (Table 66-4). Yoldia amygdalea was associated with sedi- ment types ranging from medium sand to medium silt (; Tables 66-1 and 66-2, Figs. 66-2 to 66-6, 66-12, and 66-13, Table 66-5). Major Component of.
