Batiacasphaera sahii
Batiacasphaera? sahii, (Khanna and Singh, 1981), Lentin and Williams, 1993
Originally Hexagonifera, subsequently (and now) Batiacasphaera?. Khanna and Singh, 1981, stated that this species is cavate and has an apical archeopyle; however, no cavation is obvious on the holotype (fig.2, no.2). Accordingly, we questionably transfer it to Batiacasphaera, as Batiacasphaera? sahii. The specimen illustrated in Khanna and Singh, 1981, fig.4, no.4; text-fig.5, appears to represent another species of unknown generic assignment. Khowaja-Ateequzzaman, 1991, correctly noted that this species name was a nomen nudum in Singh et al., 1979, Khanna, 1979, and Khanna et al., 1981.
Holotype: Khanna and Singh, 1981, fig.2, no.2.
Age: Early-Middle Eocene
