Mimachlamys curtisiana Iredale, 1939
IREDALE, T. 1939. Mollusca. Part 1. In Great Barrier Reef Expedition 1928-29, B.M.(N.H.), Scientific Reports, 5 (6): 209-425, pls. 1-7. [p. 351, pl. 5, figs. 19, 19a]
«Mimachlamys curtisiana sp. nov. (Plate V, figs. 19, 19a.)
Smith in the "Alert" Report (p. 116) included Pecten funebris Reeve ('Conch. Icon.' VIII, pI. xxii, sp. and fig. 85, May, 1853: "Bathurst, Australia" = Bathurst Island, Northern Australia), from Port Curtis, collected by Coppinger, and hence this specific name appears in the Queensland list. Many specimens from Port Curtis disagree in shape, number of ribs and detailed sculpture with Reeve's figure, and specimens from North-West Australia exactly coincide with the latter, so that the Queensland shell is here described. The specimen I recorded ('Proc. Zool. Soc. (Lond.), 1914, p. 666) from the Monte Bello Islands as C. lentiginosus var. is undoubtedly funebris, and Hedley, in his West Australian list, included it as P. cruentatus Reeve var. lentiginosus Reeve, which entry must now be amended to funebris Reeve. The Port Curtis shell is comparatively small, both valves convex, the left of greater convexity than the right, posterior ear very small, right ear fairly large, shell stout for its size. The ribs are rounded, twenty to twentytwo in number, bearing regular rather crowded erect scales, which become a little less prominent with age. The umbonal portion is smooth and is followed by well-developed radial ribs, the interstitial sculpturing varying a little in the two valves; a punctulate "Camptonectes" form persisting in the left valve, but being replaced at an early stage by a radial scratching in the right valve. The type measures: height 28 mm., breadth 25 mm.»
