«Pecten (Camptonectes) Hectori sp. nov. Plate XI, figs. 6-9; Plate Xll, fig. 1.
Description.— Shell ovate, pointed dorsally, inequilateral, higher than long. Valves moderately and nearly equally convex. Antero-dorsal margin long, concave; posterodorsal margin shorter, slightly convex. Anterior ear of right valve large, with its front margin nearly perpendicular to the hinge-line; posterior ear small, obtusely triangular. Anterior ear of left valve large, triangular, with its outer angle rather larger than a right angle; posterior ear small. Ornamentation of the left valve consists of numerous radial furrows curving outwards, with flat interspaces.*
Affinities.—The right valve resembles that of Pecten occulte-striatus Zittel,† from the Senonian of Gosau, but the antero-dorsal margin is relatively longer and slopes less steeply, and the byssal sinus is deeper. It is also similar to a species‡ from the Senonian of Pondoland, but the antero-dorsal margin is concave, and the shell more inequilateral. Distribution.— Ostrea bed of Selwyn River (23); Weka Creek (782); Middle Waipara (762): above Deans' Coal-mine, Malvern Hills; and McKay's Creek, Middle Waipara (149). Selwyn Rapids beds of Selwyn Rapids (589). Amuri Group (calcareous conglomerate), west wing of Amuri Bluff (13); and black grit, east wing of Amuri Bluff (8).» * Owing to imperfect preservation, the ornamentation is not seen on any of the right valves.
