Description
Shell elongate-cylindrical, uniformly expanding, with bluntly rounded polar ends, spirotheca thin in inner 10 volutions where it seems composed of single thin layer, from 12th volution to maturity spirotheca thin but can be recognized in some specimens as composed of tectum, thin inner layer, and middle layer with dark lines normal to its surfaces that may be comparable to alveoli of other fusulinids, septa plane, composed of single, dense layer, foramina closely spaced, parachomata narrow, high, with circular lateral openings (*1929, *2094).
