Hystrichostrogylon membraniphorum ssp. membraniphorum
Hystrichostrogylon membraniphorum ssp. membraniphorum
Autonym
Holotype: Agelopoulos, 1964, text-fig.1
Paratype: Agelopoulos, 1964
Locus typicus: Heiligenhafen, Holstein, Germany
Stratum typicum: Late Eocene
Translation Agelopoulos, 1964: Stover and Evitt, 1978, p. 164
Original description: Agelopoulos, 1964, p. 674
Diagnosis (as for the genus): Central shell spherical to oval, apparently slightly flattened, providedd with forked spines, and enclosed by a delicate, transparent, only antapically developed, somewhat concentric outer shell that lies close to the inner shell ventrally and dorsally. Slender, long, hollow processes occur in the region of the apex which is indicated by a pylome, whereas wide, broad-surfaced processes are confined to the region of the antapex and therefore to the outer shell. The central shell within the outer shell possesses no processes.
