Current identification: Cyphantella arachnoides


Original Description
Cortical shell very delicate and thin walled, cobweb-like, with smooth surface; pores irregular, polygonal (mostly pentagonal or hexagonal), eight to ten times as broad as the thread like bars; ten to twelve on the half meridian, six to eight on the half equator. Medullary shell spheroidal, compressed, its main axis shorter than its equatorial axis, which is about one third that of the cortical shell. (This species is very similar to the middle part of the shell of Ommatocampe profundissima., Ehrenberg, 1872, Abhandl. d. k. Akad. d. Wiss. Berlin, Taf. viii. fig. 6.)

Size: Main axis of the cortical shell 0.11, equatorial axis 0.06; meshes 0.01 to 0.02, bars 0.002; diameter of the medullary shell 0.02.

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