Abstract

The genus Rossiella Desikachary & Maheshwari occurs in the Miocene deposits, both in onshore deposits and in deep-sea cores. Six species of this genus, viz., R. paleacea, R. elongata (Barron) Desikachary comb. nov., R. tatsunokuchiensis, R. praepaleacea, R. moholensis (Schrader) Desikachary comb. Nov. and R. gombosi Desikachary sp. nov. are described and discussed. The authors consider Rossiella and Cussia Schrader as congeneric. Bogorovia Jouse, as typified by B. veniamini, is considered distinct from Rossiella.
