MARSHALL, P. 1918. The Tertiary molluscan fauna of Pakaurangi Point. Kaipara Harbour. Transactions of the Royal Society of New Zealand, 50: 263-277 [p. 273, pl. 22, figs. 4-6]
«Pecten subconvexus n. sp. (Plate XXII, figs. 1, 5, 6.)
Shell small, fan-shaped: height, 16 mm.; breadth, 16 mm.: slightly, inequilateral. Ventral margin nearly circular. Ears unequal, the anterior distinctly the larger with 6 radiating scaly ribs; posterior ear relatively small but with the same number of ribs, though they are less scaly and less prominent than those of the anterior rib. The shell has a large number of rounded radiating ribs. Intervening grooves usually much narrower than the ribs, and both the grooves and the ribs are marked by a large number of fine cross-lines. In some valves some 5 large radiating undulations can be distinguished.
Mr. Suter, who kindly examined these specimens for me, remarks that the species is near to P. convexus Q. & G. This species is fairly abundant at Pakaurangi Point. Type in the Wanganui Museum.» PATRICK MARSHALL, 1918
