Horologinella lineata
Horologinella lineata Cookson and Eisenack, 1962
Holotype: Cookson and Eisenack, 1962a, pl.37, figs.1–2; Pestchevitskaya, 2001, pl.2, figs.17a–b; Pestchevitskaya, 2003, pl.2, fig.9 (not fig.8).
Paratype: Cookson and Eisenack, 1962
Locus typicus: Attadale Bore, near Perth, W.A. at 619 ft
Stratum typicum: Aptian-?Albian
Original description: Cookson and Eisenack, 1962, p.272
Shell approximately isodiametric divided by a relatively deep median incision on both sides into an epitheca and hypotheca of nearly the same shape. The epitheca bears a small beak-like projection adjacent to which in the mid-line lies a small, concave, terminal opening. The surface of the shell is tabulated the arrangement and shape of the fields being different on the two surfaces which for convenience are distinguished as ventral and dorsal respectively. The ventral surface is characterized by a long field which narrows gradually from near the epithecal opening to the "waist line" the remaining fields being polygonal in outline and variable in shape. The dorsal surface is divided into approximately 6 relatively large 4-5 sided fields. The wall of the shell is relatively thick and finely granular.
Dimensions: Holotype30 Ám long, 25 Ám broad. Paratype (fig. 3)--24 Ám long, 25 Ám broad; another example 22 Ám long, 23 Ám broad.
