本文记述了产于俄亥俄州页岩上泥盆统休伦段3个钙质结核中的放射虫57种，其中55新种，分布于11属，8新种。其中，5个是spumelline形式，2个被解释为原始的martellarians。其中5种被怀疑归属于古生代Albaillellidae Deflandre，1952，5种被分类为未定种（incertae sedis）。由于保存得异常完好，这一材料部分阐明了晚期放射虫的祖先。
Fifty-seven species of Radiolaria, 55 of them new, distributed among 11 genera, 8 of them new, are described from 3 calcareous concretions of the Upper Devonian Huron Member of the Ohio Shale. Of these, 5 are spumelline forms and 2 are interpreted as primitive cyrtellarians. Five species are doubtfully assigned to the Paleozoic family Albaillellidae Deflandre, 1952, and 5 are classed incertae sedis. This material, because of its unusually fine preservation, partially elucidates the ancestry of later Radiolaria.
