Not Clorodius Desmarest, 1823 ; de Haan, 1833. I am unable to agree with Bathbun and Ortmann as to the necessity for a new name for this genus, and prefer to follow Alcock in considering that Milne-Edwards's name holds good. 50. CHLORODIUS NIGER (Forskai), 1775. Cancer niger, Forskai, Descr. Anim. p. 89 (1775). Clorodius niger, Riippell, Krabben roth. Meer. p. 20, pi. iv. fig. 7 & pi. vi. fig. 14. Chlorodius niger, H.

The lobes of the antero-lateral edge in all the specimens are low and rounded, and not procurved into spines. . Funafuti; one male, one female. Botuma ; five males, four females. 51. CHLORODIUS BARBATUS, n. sp. (Plate XLI. fig. 4.) Diagnosis: " A small Chlorodius with the areas of the carapace faintly demarked; chelipeds unequal; the fingers of the large hand widely gaping, less strongly toothed than in C. Icevissimus Dana 1852, and more hollowed at the tip ; the large hand bearing a tuft of hairs at the base of the fingers on the outside, hiding the proximal part of the fingers; the first tooth of the antero-lateral edge wanting altogether, and not, as in C. Icevissimus, merely obsolescent." The third maxilliped is shown in fig. 4«, and the abdomen of the male in fig. 46. Colour in spirit: white with brown fingers. Measurements of largest specimen (a male) : length 4*5 mm.; tip to tip of longest side-teeth 7 mm.; front 7 mm.; fronto-orbital breadth 6 mm. The species is closely allied to C. Icevissimus Dana, but differs from it in several points indicated in the definition. Funafuti; thirty-five males and twenty-four females, all but one male from 15-25 fathoms. Botuma; eleven males, seven females. Genus PHYMODIUS A. M.-Edw., 1863. 52. PHYMODIUS UNGULATUS (H. M.-Edw.), 1834. Chlorodius ungulatus, H. M.-Edwards, H. N.
