Catalog entries: Sphaeropyle robusta

Original description: Four concentric shells. Innermost shell robust, spherical, with circular pores of uniform size, irregularly arranged, 34 per half-circumference. Second shell (outward) robust, spherical,
with circular pores of fairly uniform size, quincuncially arranged, 6-7 per half-circumference, weakly framed. Third shell, usually
relatively thin-walled (particularly in later representatives), spherical to subspherical, with circular pores of variable size but conspicuously large relative to other shells, 7-9 per half-circumference, with tiny by-spines at most bar intersections. Cortical shell robust, subspherical to elongate, protruding at one end, bearing a pylome which is surrounded with a corona of stout teeth; pores circular, irregularly arranged, usually with well-developed frames, about 20 per half-circumference; bar intersections often developed into short by-spines.

Approximately 6 radial bars connect the inner three shells, many
times this number between cortical and next inner shell. Stout radial main-spines are usually short in Leg 18 material, but appear broken and could be better developed (preserved) elsewhere.
Remarks on original description: Earlier populations are smaller with peristomal teeth fused into a rim. They are otherwise similar although it may eventually be possible to separate these forms as a new species.
This species is found in high and middle latitude sediments
