TYPE SPECIES . — Diploplegma cinctum Hinde, 1890 ( Hinde 1890: 48 , pl. 3, fig. 10). AGE AND LOCATION OF TYPE MATERIAL . —Upper Dapingian-Sandbian, Middle Ordovician from cherts in the Southern Uplands, Scotland . TAXON CODE. — 308. STATUS. — Nomen dubium . DIAGNOSIS. — “Liosphaerida with a relatively large inner (cortical?) test of irregularly reticulate or spongy framework and an outer shell of the same structure, the two connected by radial bars. In this genus the inner test is sufficiently large to be regarded as an inner cortical shell, and in this respect it resembles Liosphaera , Haeckel (‘Challenger’ Report, pt. i. p. 76), which has two cortical shells. It differs from Liosphaera , however, in the irregularly reticulate or spongy nature of tests.” ( Hinde 1890: 48 ). REMARK It is not possible to determine the nature of this radiolarian from the figured specimen.
