«Testa tenuissima, planulata, paulo inaequivalvis, albida, haud nitida, concentrice valde plicata, plicis utrinque attenuatis, undique confertim et tenuiter lirata. Auriculae inaequales, anticis majoribus, antica valva; dextrae liris gracilibus paucis squamulatis ornata, inferne profunde sinuata.
Length 18½ mm., height 20, diameter 5.
Habitat.— Station 146, east of Marion Island, in 1375 fathoms; Globigerina ooze. This beautiful species is very like Pecten fragilis of Jeffreys, but appears to differ somewhat in form and in having both valves similarly plicate and lirate. The auricles also are not "equal in size," the anterior being decidedly larger than the posterior. The right valve is rather flatter than the left, and its anterior auricle is deeply incised underneath, the upper half of it being ornamented with four or five finely squamate slender lirae.» EDGAR ALBERT SMITH, 1885
