Original description Description: Test is large, elongate, with two stages of growth: initial planispiral part and rectilinear later part. Planispiral part has one to one and a half voluions. Septa are straight and short in this part. Straight part contains 2-8 chambers. Septa of this part are almost horizontal or with a slight inclination to the axis, and are thick; they are similar to the wall in structure. Wall is calcareous, single layered, coarsely granular, and thick. The wall consists of large grains of calcite that create the impression of an agglutinated wall. The calcareous composition of these grains was confirmed by examining the wall structure with polarized light. Aperture is terminal and simple.
Occurrence: USA, New Mexico, Gaudalupe Mountains, Dark Canyon; the upper part of the Yates and Tansill formations.
Range: Middle Permian (Capitanian).
(Nestell and Nestell (2006)).
