Samlandia reticulifera
Samlandia reticulifera Cookson and Eisenack, 1965
Holotype: Cookson and Eisenack, 1965, pl.15, fig.10
Locus typicus: Browns Creek Clays, SW. Victoria
Stratum typicum: Eocene
Original description: Cookson and Eisenack, 1965, p.126
Shell oval with a short, conical, apical and antapical projection and two lower, broader or less clearly defined projections in an equatorial position, one on each side. Wall of shell 2-layered, the inner ornamented by a complete or incomplete reticulum. The relatively thick muri support short, thin, closely and vertically arranged appendages with broadened apices (Pl.15 fig. 15) which, by their close approximation and possible coalescence, form the closely opposed outer thin layer of the wall. The archeopyle is sub-apical and the operculum approximately quadrangular or rectangular in outline.
Dimensions: Holotype--c. 114 µm long, c. 94 µm wide. Range--c. 80-114 µm long, c. 70-95 µm wide.
Affinities:
Cookson and Eisenack, 1965, p.127: S. reticulifera differs from the genotype S. chlamydophora (Eisenack 1963, Pl. 2, fig. 14) in the prominent reticulation of the inner layer of the wall and the close approximation of the enclosing membrane. In S. chlamydophora the outer membrane is widely separated from the inner wall and is supported by long unbranched lamellae. The archeopyle is sub-apical in both species.
