( Fig. 13D)

Material examined. RV Hakuhō Maru KH-72-1 cruise, sta. 29, 2 ƏƏ ( CB 29.5 mm excluding lateral tubercles×CL 20.4 mm; 29.8× 20.8 mm), NSMT-Cr 30732; 1 ovig. $ (24.4× 17.3 mm), NSMT-Cr 30733; 1$ (27.1× 18.9 mm), NSMT-Cr 30734. — Sta. 30, 1Ə ( CB 29.3 mm excluding lateral tubercles× CL 17.8 mm), 1 ovig. $ (31.2× 18.5 mm), NSMT-Cr 30735.

Remarks. Three males and three females, of which two females are ovigerous, agree well with the photographs of Portunus gracilimanus given by Stephenson and Campbell (1959: pl. 4 fig. 1, pl. 5 fig. M), Takeda and Miyake (1969a: fig. 1), and Dai and Yang (1981: pl. 27 fig. 6) in the characteristic arrangements of the epi- and protogastric linear, transverse ridges of the carapace, and both cheliped fingers being rather prominently curved outward at the tips. Figures were also given by A. Milne-Edwards (1861) as Achelous Whitei A. Milne-Edwards , and by Chopra (1935) and Shen (1937) as Neptunus (Lupo- cycloporus) gracilimanus .

Distribution. Widely distributed in the Indo-West Pacific from the East China Sea southwards to Queensland, Australia and westwards to the east coast of India, 5–55 m depth.
