DIAGNOSIS (English translation of Nazarov [1975b] by E. Roden – in the rad database microfiche collection of Bill Riedel). — “The small shell is irregularly spherical in outline and has short outer spines. The short conical spines which are tapered at the distal end, are best expressed around the pores. Thin outer shell of the skeleton with irregularly distributed angularly oval, more rarely hexagonal pores. To judge from sections, the inner spine was centrally located. Because of the poor preservation of the material at hand, the number of its rays is hard to establish, but obviously there were not more than ten.” (translated from Nazarov 1973: 8).

REMARKS

It is not possible to determine the nature of this radiolarian from the figured specimen. However, Nazarov (1975b) reassigns the type specimen to Polyentactinia Foreman, 1963 .
