Leptochelia tenuis (G. M. Thomson), 1880.
Paratanais tenuis Thomson, 1880: 2, pl. 1, fig. 1.
Thomson, 1881: 207–208.
Heterotanais tenuis, Thomson, 1913: 245.
Thomson, 1921: 113.
Leptochelia mirabilis Stebbing, 1905: 6–7, pl. 1.B.
Material Examined: Station BOL (VUZ. 43), 1 specimen; Station GUL (VUZ. 54), several specimens, 1-2-2-2 mm length, 1 female ovigerous at 1–7 mm.
Distribution: Dunedin Harbour; rock pools along the coast: Cook Strait; Gulf of Manaar, Ceylon.
Discussion: Although Thomson's figures are a little sketchy, there is no difficulty in identifying these specimens with his species. The specimens were referred to Dr. Karl Lang of the Naturhistoriska Riksmuseet of Stockholm for generic confirmation and I am grateful to him for the following comment: "There can be no doubt that Paratanais tenuis is the same species which Stebbing (1905) has described as Leptochelia mirabilis. The species is consequently to be named Leptochelia tenuis (Thomson) and L. mirabilis is a synonym of this species."
