Amphora spectabilis Gregory Figs 3, 4

Ref. illus.: Levkov 2009, p. 265, pl. 114, figs 1–5, pl. 252, figs 1–5 (SEM).

Samples: GU55B-5

Dimensions: Length 30 µm, width 12 µm, stria density 8 in 10 µm (dorsal) and 13 in 10 µm (ventral)

Diagnostics: More strongly and coarsely striated on the dorsal surface, dorsal striae often biseriate and bifurcating towards the sternum, ventral striae uniseriate.

Comment: Our specimens (seen also in Yap and Palau) are much shorter than the 68–129 µm given by Levkov (2009). A Palauan specimen (Fig. 4) seen in SEM shows that the striae are mostly biseriate, the bifurcations resulting from the two rows diverging; these images conform to the specimens shown by Levkov in SEM.
