Alpheus socialis Heller, Voy. “Novara,” Crust., p. 106, pl. 10, fig. 1, 1865; Miers, Cat. N.Z. Crust., p. 82, 1876; G. M. Thomson, Trans. Linn. Soc., Zool., 8, p. 436, pl. 27, figs. 6–12, 1903.

Two specimens from under stones at low-water mark, Coral Bay, Sunday Island, collected by Mr. T. Iredale.

In one of my specimens the right cheliped is the larger, while in the other it is the left; Thomson
