Catalog entries: Spongoliva
Original description: Spongurida with spongy ellipsoidal cortical shell, enclosing a double, spherical or ellipsoidal, latticed medullary shell. Polar spines absent.
The genus Spongoliva differs from the nearest Spongodruppa by duplication of the medullary shell; it bears therefore the same relation to this that Prunulum does to Druppulla, and can be regarded as a Prunulum, in which the simple latticed cortical shell is replaced by a spongy framework.
