Original Description
Hemispherical dipleuric shell having eight slender, divergent, straight, twiglike legs with small, scattered thorns or merely roughened along the outer edge; shell divided by usually deep sagittal groove, but the two lobes are only slightly separated; the surface having circular or even squarish gatelike pores; the framework thick and having short spines especially on the sides and coryphal surface. Distinguishing characters (rw): Gorgospyris cystophora n. sp. has fewer feet (eight) than G. lamellosa Haeckel (1887) (Barbados), which has fifteen to twenty-five. The shape of the shell differs from that of G. eurycolpos Haeckel (1887) (Recent, Pacific), and the arms are rodlike without papillate knobs as in . G. lirope Haeckel (1887) (Recent, Atlantic), a species in which the shell resembles that of the Eocene G. cystophora n. sp. The remaining species have more than eight feet.
