Description
Solitary, not large, in early stages septa dilated leaving few interspaces, in cardinal quadrants major septa short and pinnate about fossula with short cardinal septum, in counter quadrants major septa long, counter septum may be very long, minor septa vestigial, as traces on upper surfaces of dissepiments in marginarium that is wider in counter quadrants than in cardinal, lonsdaleoid dissepiments develop in later stages, septa thinning first in counter quadrants, tabulae incomplete, floors declined into fossula on convex side of corallum. [There is no confirmation of Yu's view (1963, p. 310) that septal insertion occurs in counter sextants; see PAPOYAN, 1974, p. 205.]
