Fibrocysta exiguapicis
Fibrocysta exiguapicis Islam, 1983
Holotype: Islam, 1983, pl.2, fig.10
Paratype: Islam, 1983
Locus typicus: Hampshire Basin, S England
Stratum typicum: Early Eocene
Original diagnosis: Islam, 1983, p. 338
Cyst ellipsoidal, up to 2 Ám thick, skolochorate and strongly fibroreticulate; many nontabular fibrous processes, solid, thick and stout, proximally broad and frequently joined together up to about midlength, tapering to bifid, branched or aculeate distal extremities; apical prominence indicated by group of proximally joined processes or short blunt apical horn; antapical prominence similar or absent; archeopyle precingular type P.
Dimensions: Holotype: cyst body 54 x 49 Ám, length of processes 19-23 m. Range: cyst length 62(53)47 Ám, breadth 52(48)44 Ám, length of processes 14-23 Ám. Specimens measured: 10.
Islam, 1983, p. 338: This species differs from others of the genus in possessing thick and stout processes that are frequently proximally joined, and less prominent apical and antapical features. The antapical feature is often absent.
