Diagnosis Test lenticular, globular proloculus followed by cornuspirine tubular undivided seco"1d chamber forming about one whorl, then with gradually shortened chambers of one to onehalf whorls in length, coiling involute; wall thick, that of later whorls completely overlapping the early ones to produce a thick umbonal region, chamber lumen restricted to the peripheral area of the test, composition of the fossil test is siliceous, probably due to replacement of an originally porcelaneous calcareous wall; aperture terminal, rounded, with thickened rim, projecting somewhat above the periphery as a result of the strongly thickened chamber floor that distally restricts the chamber diameter. M. Triassic (Anisian); Turkey. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
