Original Description

General shape similar to Glt. marginata austinensis; size, however, smaller; a double keel faint and present, in a continuous manner only in the early stages; chambers less and less overlapping toward the adult stage, growing more inflated, central depression, therefore, more pronounced. The sutures on the ventral side are radial, only a slight thickening toward the umbilicus occasionally testifies the disappearance of the umbilical raised sutures. On the dorsal side the sutures are raised and finely beaded only in the early stages. The terminal face of the last chambers maintains its triangular shape, being subangular along' the once present sutural elevations. The test is smooth, somewhat rougher in the early stages, dextrally coiling.

Size:
Dimensions of holotype: Width 0.32 x 0.28 mm.; thickness, 0.16 mm.
