Polydora quadrilobata Jacobi, 1883 (Spionidae). Abundant in sand and mud
on the lower shore and subtidally in several localities in SW Iceland and one
in NW Iceland (Fig. 2). Taken with young (20—25 segments in tubes in late
March and early April.
Pygospio elegans Claparede, 1863 (Spionidae). Found at three localities in
SW Iceland; intertidally, in shallow water, and in a coastal pond (salinity 24—
