no SMITHSONIAN MISCELLANEOUS COLLECTIONS 



with somewhat truncated extremities. Ambulatory feet, with the 

 exception of the terminal joints, naked, nearly smooth, but slightly 

 rugose, the rugae being similar in character to those in 0. ceratoph- 

 thalma, but much less strongly developed. Abdomen (of 'the fe- 

 male) with the penult joint deeply sinuated; the terminal joint set in 

 the bottom of the sinus, and reaching fully to, or a little beyond, the 

 bases of the maxillipeds. Dimensions of the carapax : Length, 0.92 ; 

 breadth, between the orbital angles, 0.96 inch. 



It differs from O. cordimana in the character of the maxillipeds, 

 smaller hand and feet. 



Found at Simoda. Japan.

Plate XV, Fig. 2 



Ocypodc cordiiiiana Desm.\rest, Consicl. sur les Crust, 121. Milne 

 Edw.-\rds, jNIel. Carcin., p. 107. 



The species here referred to O. cordimana, is distinguished by its 

 convex, faintly granulated carapax, little oblique orbits, little prom- 

 inent orbital angle, immediately behind which the lateral margin is 

 convex. The dentiform internal suborbital lobe is compressed, 

 rather broad and smooth, not denticulated. The buccal area is 

 small, narrowed anteriorly, with straight sides, and is neatly covered 

 by the external maxillipeds, which are not protuberant, as in most 

 species. The surface of the maxillipeds is glossy, with a few 

 sparsely scattered granules or points ; the meros- joint is depressed 

 in the middle, with a ridge on either side, as in O. ceratophthalma, 

 but not much granulated. The feet are nearly smooth, although 

 there are indications, on the meros- and carpus- joints, of the spinules 

 mentioned in Milne Edwards's description. They are somewhat 

 pilose toward their extremities. Dactylus of last pair much curved 

 upward and outward. Abdomen of the male much broader than in 

 other species. 



Found at Hongkong and at Loo Choo. 



173. OCYPODE L^VIS Dana 



Ocypode Icevis Dana, U. S. Expl. Exped., Crust., i, 325, pi. xx, fig. 2. 



A small, well marked species, easily distinguished by the character 

 of the larger hand, which is much dilated below, and has very short 

 and thick fingers. Our specimen is somewhat larger than those 

 found bv Dana.
