«Sp. valva superiore oblique ovata, moderate convexa, irregulariter undulate rugosa, radiatim dense costellata, costellis lateraliter compressis, rugulis, sulcis profundis aequldistantibus separatis, hie et illic tuberculis crassis, squamiformibus instructis; umbone depresso; auriculis sub-aequalibus, radiatim costellatis; lunula angusta et profunda.
The irregular undulations on the surface of the upper valve seem to be, to a certain extent at least, characteristic of this species, and have probably been produced by the shell having been sessile on corals, to which fragments have been found attached. The most marked character of the species consists in the radiating, sharp, laterally compressed ribs, these being separated by deep furrows, in thickness equal to the ribs; a few strong tubercles occur on their surface, but the ribs themselves are not thickened.
Locality.— North of Poodoopolliam, in a white earthy limestone. Formation.— Arrialoor group.» FERDINAND STOLICZKA, 1871
