The Chlorodius nodosus of Randall, as figured by Dana (/. ci), is evidently the same species and variety as the specimens from Duke-of-York Island, and is not, I think, distinct from C. sanguineus as figured by the same author. The principal character that differentiates this variety from the typical exaratus is the presence of an additional small tooth behind the last tooth of the antero-lateral margins. C. sanguineus is considered a distinct species by Dana, and, with some hesitation, by A. Milne-Edwards, but was united with C. exaratus by Stimpson in his preliminary " Report on the Crustacea collected by the United-States Expedition to the North Pacific" (Proc. Ac. Nat. Sci. Phil. p. 34, 1858). OziUS RUGULOSUS. Ozius rugulosus, Stimpson, Proc. Ac. Nat. Sci. Phil. p. 34 (1858); Heller, Voy. Novara, Crust, p. 22, pl. iii. fig. 1 (1865); A. M.-Edw. Nouv. Archiv. Mus. Hist. Nat. ix. p. 240, pl. xi. fig. 3 (1873). Three specimens of this species are in the collection-two females and a young male. Specimens are in the British-Museum collection from the Mauritius, Australian coast, and New Hebrides; and it has been recorded from the Nicobars, Bonin Islands, Tahiti, and New Caledonia. Thus it is evident that its range extends over the whole Indo-Pacific region ; but it is probably nowhere a common species. ERIPHIA LiEVIMANA. Eriphia Icevimana, M.-Edw. Hist. Nat. Crust, i. p. 427 (1834) ; Dana, U.S. Expl. Exp. xiii. Crust, i. p. 249, pl. xiv. fig. 7 (1852) ; A. M.-Edw. Nouv. Archiv. Mus. Hist. Nat. ix. p. 255 (1873). Two males and four females were collected by Mr. Brown. In the young animal the series of tubercles upon the frontal margin are not developed, the margin appearing subentire; but those on the postfrontal region and antero-lateral margins are clearly distinguishable. E. Icevimana is distributed throughout the Indo-Pacific region; there are specimens in the collection of the British Museum, from Madagascar and the Mauritius, that certainly belong to this species, and not to the allied E. smithii of M'Leay (Annulosa in Smith's Zool. S. Africa, p. 60), figured by Krauss (Sud-Afrikan. Krust. p. 36, pl. ii. fig. 3, 1843), of which specimens, from Port Natal, are in the Museum collection. OCYPODE CERATOPHTHALMA. Cancer ceratophthalmus, Pallas, Spic. Zool. ix. p. 83. pl. v. figs. 7,8(1772). Ocypode ceratophlhalma, Fabr. Ent. Syst. Suppl. p. 347 (1798) ; M.-Edw. Hist. Nat. Crust, ii. p. 48 (1837); Regne Animal de Cuvier, Atlas, Crust, pl. xvii. fig. 1 ; Ann. Sci. Nat. (Ser. 3) Zool. xviii. p. 141 (1852); A. M.-Edw. Nouv. Archiv. Mus. Hist.. Nat. ix. p. 270 (1873). In the collection are two specimens of an Ocypode, males, and both in a mutilated condition, which I refer to this species. In both specimens are to be seen the large orange-red blotches on the sides |
