Amphora sp. 1 ( Figures 87, 88 )

Description: Length 26–34 µm, width 4.5–6 µm, striae very fine and difficult to resolve in LM.

Remarks: This species is very similar to the images given by Simonsen (1992, page 73, plate 69, figures 12, 13) for Amphora lunula var. parvula Heiden , as published in Heiden and Kolbe (1928), of material collected from Antarctica. Simonsen, however, doubted the identification of this taxon which may belong to a different species.

Ecology and distribution: Marine species. Rare in Potter Cove.
