Original Description

Cortical shell thick walled, with irregular, roundish pores, twice to five times as broad as the bars; eighteen to twenty-four on the half equator. Between them arise over the entire surface small conical thorns, not longer than the largest pores. Irregularly scattered over the surface twenty to thirty strong, conical, radial spines, about half as long as the main axis, as broad at the base as a large pore. Both medullary shells ellipsoidal, their main axis identical with that of the cortical shell.

Size:
Major axis of the outer shell 0.18, of the middle 0.09, of the inner 0.05; minor axis of the first 0.14, of the second 0.07, of the third 0.04; pores of the cortical shell 0.006 to 0.02, bars 0.004; length of the spines 0.1, basal breadth 0.01.

Editors' Notes
There was no illustration of this species in Haeckel (1887)
Haeckel listed Prunocarpus melocacus under the subgeneric name Prunocarpilla, but did not include the subgeneric name in the species name.

Stratigraphic information for LM21 from Riedel, 1959, p.287.[comment from RadWorld database]
