Original Description
Shell of moderate size, generally subrectangular, with only a slight median indentation on coryphal face, lateral sides parallel, a little convex, and slightly contracted toward basal plate, whole shell much like a high crown; great-circle a thin, prismatic hoop on inside of shell; pores small, subcircular to subelliptical, greatly differing in size even in same transverse row, in five to six transverse, subregular rows, numerous; framework delicate, generally lacelike, thin, with wide, clear shell-substance between pores which are well-separated, and with slightly sinuous transverse lines between parallel, adjacent pore rows; surface without spines or thorns; feet nine (?) or more (much broken in our single specimen), cross-connected by transverse and oblique bars somewhat as in feet of Acrospyris clathrocanium (Haeckel, 1887, pl.95, fig.17) with vertical subdivisions so that enclosed area forms an extension of lacy network of shell framework, feet bifurcate in upper 0.3 or 0.5, angled in section, bars and feet with occasional thorns; interspaces between legs low arches; basal plate with three large pores and several odd, small ones, large ones arranged like a clover leaf.

Transdiameter of widest level of shell, 92.4┬Ám. Distinguishing characters (rw): Gorgospyris perplexus n. sp. is so peculiar and rare that it is not apt to be confused with other species. Doubtfully assigned to genus and subgenus to which it is here allocated.

Editors' Notes
[Campbell and Clark here questionably list this species under the subgeneric name Thamnosphris (?) [sic, it should be (Thamnospyris)] and include the subgeneric name in the species name.
