Original Description
Shell subequally dipleuric, hemispherical, with eight relatively short, slender, straight, divergent, twiglike feet, their tips sharp, and the outer sides roughened; shell divided by a vertical, fairly deep, groovelike, sagittal stricture, the two lobes relatively adherent, the surface with large, oval, subcircular, or squarish, gatelike pores, five on one side of one lobe, in three rather regular rows, the largest pores median; otherwise the shell as in G. cystophora cystophora n. subsp.

Length of shell, 69.4µm; of foot, 21.0µm; breadth of shell, 102.4µm; diameter of largest gate-pore, 25.4µm. Distinguishing characters (rw): Gorgospyris cystophora brevipes n. subsp. differs chiefly from G. cystophora cystophora n. subsp. in having shorter feet (not very well shown in the photograph since the specimen was oriented in such a way that the feet were not in the best focus when the shell was) and in lacking spines over the shell surface.

Editors' Notes
