«4. Genus SECTIPECTEN novo
Type: Pecten wollastoni Finlay (= Pecten sectus Hutton). (1) Subgenus Sectipecten s. str. Shell large, strong, subequilateral, both valves inflated, right sometimes more than the left; ears large, subequal, byssal sinus restrained, no ctenolium. Sculpture: right valve with about eight strong, rectangular folds separated by somewhat narrower, flat interspaces. The ribs later on divide, but the divisions remain grouped together and raised above the interspace which by now has developed one to three secondary ribs. Left valve with about eight strong ribs with much wider, flat interspaccs. The ribs are generally grooved down the middle, sometimes deeply so and appear as double ribs. Secondary grooves are also developed, and in the interspaccs are from two to five riblets. The whole surface except the flat summits of the ribs in the right valve with crowded, fine, regular, sharp concentric ridges. Hinge-crura scarcely developed.
