Original description General description. A large, elongate to inflated fusiform genus of six to seven volutions, attaining a length of 11 to 15 mm and a diameter of 4.5 to 8 mm. Straight to concave or convex lateral slopes end in bluntly pointed to rounded poles. The proloc- ulus is large, ranging from 0.325 to 0.575 mm in outside diameter. The generally thick spirotheca ranges from 0.125 to 0.400 mm in maximum thickness. Septa are highly folded pole to pole. Septal folds commonly reach the entire chamber height in the center of the test, are evenly to irregularly spaced, and generally form chamberlets toward the poles. Thick and irregular vesicular flut- ing similar to that in Triticites characterizes the axial region. Axial filling is absent. Massive and asymmetrical chomata, which commonly are present in all but the last two volutions, commonly reach the entire chamber height; in some species they appear to be fused to the overlying spirotheca. The narrow tunnel angle ranges from 9 to 45°, with a typical value of 10 to 15°. Cuniculi are present in both species assigned to this genus.
Age. Middle Wolfcampian. East-central California.
