REMARKS

Acanthotetrapaurinella kennecottensis Group includes three different morphotypes: a. Subtetrahedral test with polygonal pore frames and long primary spines (e.g. Tipperella kennecottensis [ Longridge et al. 2007: only pl. 7, fig. 7; Carter & Hori 2005: pl.1A, fig.4; pl.1B,fig.4]); b. Subtetrahedral test with polygonal pore frames and short primary spines(e.g. Tipperella kennecottensis [this study: Fig. 8 A-F); and c. Subsphaerical to subtetrahedral test with spongy meshwork (e.g. Spongotrochus sp. [ Carter 1994: pl. 1, fig.7]; Tipperella kennecottensis [ Longridge et al. 2007: pl.7 fig.11]; Tozerium nascens Whalen & Carter, 1998 [ Tekin 2002a: 189, pl.4, fig.1]; Tipperella kennecottensis [this study: Fig.8 G-H]).
