Diagnosis Test free, large, flattened, early stage planispirally enrolled and evolute, later uncoiled and rectilinear, with broad, low and centrally arched uniserial chambers, interior subdivided by vertical exoskeletal beams that project from the outer wall a short distance into the chamber cavity, those of successive chambers not aligned, vertical beams interconnected by few horizontal rafters, probably only one horizontal partition per chamber, leaving the lower half of the chamber lumen open in the interior; wall calcareous, microgranular, agglutinated, a few large globular particles incorporated in the septa; aperture apparently multiple, a row of small pores in the terminal face. M. Jurassic (Bathonian, and possibly U. Bajocian); Saudi Arabia. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
