218 COLLECTIONS FEOM MELANESIA.Etisodes sciilptilis, Heller, Sitz. Akad. Wien, Math.-nut. Klasse, xliii.(i.) p. 333 (1861) ;A. 3I.-Edivards, Nouv. Archiv. Mus. Hist. Nat.ix. p. 230, pi. ix. lig. 2 (1873).Chlorodius samoensis, Miers, Ann. ^ Mag. Nat. Hist. ser. 4, xvi.p. 341 (3875).A small female was obtained on a coral-reef off Clairmont(No. 151).Mr. Haswell records it from Holborn Island (as E. frontalis).In the British-Musenm collection are specimens from the Gulf ofSuez (7^. MacAndmv) ; Philippines (Cuming) ; Samoa Islands (22ev.8. J. Whitmee, types of Chlorodius samoensis) ; Sandwich Islands{W. H. Pease); and others without special locality.In this very variable species the front is usually 4-lobed (withoutincluding the inner orbital angle), but sometimes the submedianincisions are so shallow that the lateral lobes are scarcely defined ; italso varies much in the distinctness of the areolation of the carapaceand the granulation of the chelipedes. I have little doubt, however,that all the forms referred to in the synonj^mical citations givenabove are varieties of one widely distributed Indo-Pacific species.51. Etisodes anaglyptus {M.-Ediv.).An adult female from Clairmont, obtained on a coral-reef (No.151), belongs here.This specimen certainly belongs to the same species as do twospecimens in the British-Museum collection from the PhilippineIslands [Cuminc/), referred by AVhite to E.anagh/ptus : but these alldiffer from Milne-Edwards's figure in the large illustrated edition ofCuvier* in having the frontal lobes divided by a deeper medianfissure, and these lobes are themselves not merely truncated but alsohave the distal ends slightly convex, and the teeth of the anterolateralmargins are somewhat more conical and acute than in thatfigure. I may add that the lobules of the carapace have a fewscattered punctulations, the tuberculation on the outer surface ofthe hands shows a disposition to arrangement in longitudinal series,and the black coloration of the fingers in the male extends over theinner and outer surface of the palms.52. Menippe (Myomenippe) legouilloui, A. M.-Edw.Several specimens are in the collection from Port Curtis, obtainedeither on the beach (Nos. 88, 96) or dredged at 7-11 fms. (No. 85).Length of the largest specimen about 1 inch 7 lines (40 millim.),greatest breadth about 2 in. 3 lines (57 millim.). In the smallerspecimens the distinctions between the median and the rest of thefrontal teeth are much less marked than in the full-sized example.In the British-Museum collection there are, besides, only aspecimen from Swan lliver, and another from the Malaysian seas,* 'Regne Animal,' Crustac^s, Atlas, pi. xi. fig. 4.
