Original Description
Cortical shell thick walled, with smooth surface, and subregular, circular pores, twice to three times as broad as the bars; eight to ten on the half meridian, sixteen to eighteen on the half equator of each chamber. Both medullary shells spherical. The cortical shell resembles very much that of Cannartiscus amphiconiscus (Pl. 39, fig. 19), but exhibits instead of the hollow polar tubes two strong solid polar spines of conical form, half as long as the main axis, and as broad at the base as the inner medullary shell.

Size: Main axis of the cortical shell (without polar spines) 0.14, greatest breadth 0.1; pores 0.008, bars 0.094; length of the polar spines 0.08, basal thickness 0.02.

Editors' Notes
There was no illustration of this species in Haeckel (1887)
Haeckel listed Cyphinidium amphistylium under the subgeneric name Cyphinidoma, but did not include the subgeneric name in the species name.[comment from RadWorld database]
