«Testa mediocriter compressa, suborbicularis, costis 19 planatis, quadratis, latioribus quam sulci, instructa, undique confertim tenuissime concentrice lamellata; valva sinistra plana, albida, rufo lineata et punctata, dextra alba, umbones versus rufo tincta; umbones laeves, acuti, contigui, haud radiatim striati, nitidi, albidi, lateribus convergentibus rectis; auriculae inaequales, posticis paulo majoribus, costis paucis radiantibus tenuibus parum conspicuis instructae, transversim tenuissime lamellatae, et linea cardinis valvae dextra squamicristata; pagina interna alba.
Longit. 25 mm., alt. 23, diam. 6. A very beautiful species well characterized by the flat-topped and square-cut costae which are rather broader than the intervening grooves. The concentric fine lamellae seem liable to disappear from the grooves in the flat valve, but they are very conspicuous on the costae and towards the umbo are thickened, so that they are more like granules than lamellae. The red markings occur both on and between the ribs. In the convex valve the lamellae are as conspicuous in the sulci as upon the costae. The lamellae upon the auricles are much more delicate and closer than those upon the rest of the shell. This species probably attains larger dimensions than those given above.» EDGAR ALBERT SMITH, 1903
