TATE, R. 1886. The lamellibranchs of Older Tertiary of Australia (part 1). Transactions and Proceedings and Report of the Royal Society of South Australia, 8: 96-158, pls. 2-12. [p. 108, pl. 10, figs. 1a-b]
«Pecten Peroni, spec. nov. Plate x., figs, 1a—1b.
Shell ovate-orbicular, equilateral, equivalve, nearly flat, umbos acute, depressed, ornamented with numerous acute or subacute scaly ribs flanked on each side by a scaly riblet; interspaces very shallow, a little wider than the ribs, minutely granular. The primary ribs vary from about 35 to 40, and with the riblets are covered by crescentic scales or short triangular spines. Ears as in P. Eyrei, but the posterior ones with the dorsal margin usually serrately fringed.
Dimensions.— Length, 39; height, 42; thickness through both valves, 11 millimetres. Localities.— Polyzoal limestone, Aldinga Bay; Adelaide bore. This species is more depressed, equilateral, and lias more ribs than P. antiaustralis and P. australis, whilst the anterior ear of the left valve is not winged. This species is dedicated to the memory of M. Peron, the naturalist to the Baudin Expedition, as a mark of my appreciation of his geological observations on Kangaroo Island.» RALPH TATE, 1886
