Schwagerininae

From Palaeos.org

The Schwagerininae, in current thinking, is a subfamily in the Schwagerinidae (Loeblich and Tappan, 1988) characterized by medium to large tests with variably fluted septa. Walls contain kariotheca rather than diaphanotheca. Previously the Schwagerininae was regarded simply as a subfamily in the Fusulinidae (sensu Cushman, e.g. 1950)
