Diagnosis Test low conical, planoconvex, all chambers visible from the convex spiral side, only the final pair of the last whorl visible on the flattened umbilical side, periphery carinate, the keel projecting from the basal surface so that it supports the test and prevents it from resting on the umbilical wall, proloculus followed by undivided coiled tubular chamber of one to three whorls that form in a single growth stage, later stage in the agamont with two broad and low crescentic chambers per whorl, under favorable conditions gamonts may reproduce immediately after formation of the spiral chamber, but semicircular chambers are formed if reproduction is delayed, distal end of the tubular chamber and of later biserial chambers turned sharply toward the umbilical area so that the aperture opens toward the umbilicus, chambers subdivided in the outer part by numerous short radial septula and may have an additional intercalated series of shorter septula, the septula extending for about the width of the chamber that is visible from the spiral side but not extending to the umbilicus of the opposite side, interior with a scroll-like median septum resulting from the sharp turn of the two edges of each chamber where the aperture is directed toward the umbilicus, those of successive whorls building a median columella; wall calcareous, acting as a single crystal of high magnesium calcite with preferred orientation of c-axis parallel to the umbilical surface and a-axis parallel to the axis of coiling, growth occurs by lateral accretion along the edge of the chamber wall and does not form an organic template, wall of a new chamber first forms on the spiral side and radial septula and underlying basal plates then arise from the peripheral carina, continued growth and fusion of the basal plates forms the lower wall of the test, basal plates in early development showing angular edges that correspond to the crystal faces and a funnel-like central depression consistent with development as a crystal skeleton in a supersaturated solution, pseudopores originate as indentations in the upper chamber wall between the septula, are filled with organic matter, and locally suppress calcification during wall construction, pores closed internally by pore sieve-plates that do not allow passage of cytoplasm but may allow transfer of gases or dissolved nutrients, test surfaces covered by a thin organic membrane continuous with that of the pore canals, that prevents deposition of secondary lamellae; aperture a low opening at the end of the semicircular chamber, where it turns sharply toward the umbilicus, later covered by a broad T-shaped apertural plate with recurved ends, apertures of successive chambers approximately 180¡ apart, each successively in a lower plane, rarely more than one aperture may be produced due to bifurcation of the chamber near the umbilical termination. L. Cretaceous (Aptian) to Holocene; cosmopolitan. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
