Erycina parva, Deshayes.

Kellia parva, Desh., Pro. Zool. Soc., 1855, p. 182. Id., Tryon, Proc. Acad. Nat. Sci. Philadelphia, (2), iii, 1872. p.231. Erycina acupuncta, Hedley, Mem. Austr. Mus., iv, 1902, p. 321, fig.60.

The species appears to be more common in New Zealand than in Australia. Mr. R. Murdoch suggested their identity to me. Comparing the few separate valves by which the species is known in Australia, I find that the New Zealand specimens are larger, being 3·6 mm. in length and 2·27 mm. in

height, more solid, and with stronger concentric sulci. I believe the two to be variants of one species.

The New Zealand shell was named for me by Mr. H. Suter, for whom in turn it was determined by Dr. W. H. Dall, probably from co-types distributed by Hugh Cuming. The occurrence of the species in space and literature induces me to suspect an error parallel to that of Ledu fastidiosa, and to conjecture that it did not come from the Philippines, but that it was originally dredged in New Zealand waters by F. Strange during the cruise of H.M.S “Acheron” in 1849.

It has been detected by Mr. R. Murdoch in the Tertiary beds of Wanganui.
