«Shell equivalve, equilateral, inflated, about as long as broad, covered with numerous compressed spiniferous ribs; the spines are of the nature of compressed imbricating squamae. There are usually from seven to nine primary ribs, two or three secondaries and a variable number of tertiaries between each pair of primary ribs, all similarly ornamented, the dimensions of the spines varying with the size of the ribs.
Front margin of valves curved or slightly crenulated, not at all angular. Ears equal, of moderate size, truncated; there is no byssal sinus. Dimensions of a largisli specimen, length and breadth, three and a-half inches; a large spine of the same, one inch. Locality and Horizon.— Upper Aiding series at Adelaide, Hallett's Cove, and Aldinga. This very handsome shell has much the appearance of a Spondylus, to which genus I had referred it until I succeeded in obtaining a specimen with a perfect umbonal region. The test in the umbonal region is very thin, and often destroyed, otherwise it is fairly thick; and as the matrix is very hard, it is impossible to work out the hinge.» RALPH TATE, 1882
