Diagnosis Test large, up to 4 mm in diameter, asymmetrical and subpolygonal to discoidal, protoconch and deuteroconch surrounded by thick wall and then by nepionic spiral, embryonic and nepionic chambers not apical but eccentric in position and situated some distance from the periphery in both microspheric and megalospheric generations, with some equatorial chambers lying between the early stage and the marginal fringe, equatorial chambers spatulate to ogival, lateral chambers present on both sides of the equatorial layer. L. Miocene (Aquitanian, ?L. Burdigalian); Mediterranean region of Europe and Africa; USA: California, Mississippi, Florida; Mexico; Puerto Rico; Ecuador; Panama; East Indies.
