Original Description
Sagittal ring subpolygonal, 63 to 68 microns high, 49 to 56 microns thick, joined directly to front and back of lattice shell. No apical or axial spines; vertical spine very short. arises near base of sagittal ring long, slender. apical connector bar; short, broad. frontal connector bar. Single, small. sculptured tubercle projects from base of sagittal ring at intersect with primary lateral bars, which are joined to basal ring; no other basal connector bars.
Basal ring subpolygonal, tribladed on back exterior surface, indented laterally and sagittally, 97 to 106 microns wide, 58 to 65 microns thick, joined directly to front and back of sagittal ring. enclosing four basal pores. Lattice bars joined to basal ring irregular in number and position. Lattice shell 157 to 193 microns high, 98 to 122 microns wide, completely enclosed. surrounding apex and base of sagittal ring; slight horizontal constriction at base of sagittal ring. Four thick lattice bars joined to front-middle, front-apex, back-apex and back-middle of saggittal ring ; tribladed on exterior surface; bear short, symmetrical pairs of lattice spines, enclose four pairs of sagittal lattice pores. Distal portions of lattice shell uniformly composed of thin, smooth, lattice bars separating small, densely spaced, subcircular, lattice pores. Sagittal lattice pores
are covered by thin, perforated, lattice plates. No lattice shell tubercles. No frontal, sternal or vertical pores.
