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. 359]
«A single left valve was dredged at Station XIV, Low Isles, and it is quite unlike any of the North-West Island shells, having notable larger ears and being flatter, with stronger sculpture. The ribs are sixteen in number, regular, not flattening dorsad, and the concentric sculpture showing over the ribs from the umbo to the dorsal margin, being stronger as usual near the edge. The ears are comparatively large and flattened, the hinge weak, the cardinal crura fine and the inside white. It measures 39 mm. in height and 43 mm. in width, across the ears 29 mm. The West Australian shell is more flattened than the eastern one, the sculpture notably much stronger, the ribbing on the right (white) valve, being flattened and broadened towards the dorsal margin, the interstices being consequently narrowed and shallow; on the left valve, which is blotched with red, the ribs are stronger and more elevated and the interspaces broad, but in this valve there is an appreciably broadening, and flattening of the ribs towards the edge of the valve. The hinge is very weak, the cardinal crura very small and the interior is pure white. It is here called Annachlamys melica sp. nov., the type being a specimen measuring 7g mm. across by 69 mm. in height, collected by Mr. Arthur Livingstone, at Broome, North West Australia.»
