Original Description

Test low trochospiral, planoconvex, nearly flat on spiral side, convex on umbilical side, lobulate; chambers arranged in 2.5 to 3 whorls; chambers petaloid, slightly inflated on spiral side, subrectangular, convex most strongly around umbilicus, on umbilical side; final whorl consisting of 4.5 to 5 chambers increasing regularly in size as added, truncated by raised, beaded double keel; wall covered by pustulae except one or two terminal chambers that are smooth; sutures raised, curved; umbilicus broad, ordered by mildly elevated umbilical shoulder; primary aperture extraumbilical-umbilical; portici broken in material examined.

Extra details from original publication
Remarks. - M. caronae sp. n. is easily distinguishable from other cooccurring species of Marginotruncana. It differs from M. pseudolinneiana PESSAGNO in being planoconvex rather than planiform and in having fewer chambers'in the final whorl; from M. marginata (REUSS) in being planoconvex rather than biconvex, in possessing less chambers in the final whorl (4½ to 5 against 6-8) and in having planoconvex chambers in cross-section rather than subglobular or globular as in M. marginata.
