228 COLLECTIONS FEOM MELANESIA.Bcarcely any intermarginal hiatus. The ambulatory legs are deficientexcept one fifth leg, which has the joints except the lastcompressed and bordered with long hairs ; the upper margin of themerus is acute and obscurely crenulated ; dactyl hairy, styliform,and short, with a small terminal claw. Colour (in spirit) light yellowishwhite. Length of carapace 3| lines (6^ millim.), breadth4i lines (about 9| millim.).The single female in the collection was obtained at ThursdayIsland, 4-5 fms. (No. 165).There is also a female in the Museum collection obtained nearJava (H.M.S. Samaranr/ '').As I have examined no male specimens of this curious species, andam ignorant of the position of the male verges, I do not venture toremove it from the vicinity of Filumnus, in which genus it is retainedby Mr. Haswell. There is, I think, no doubt of the specificidentity of our example with the specimen figured in the Catalogue'of Australian Crustacea,' though whether this be identical with theP.Jimbriatns of M.-Edwards remains somewhat uncertain, on accountof the brevity of the diagnosis of the latter author. This speciescertainly cannot be retained in Pilumnus as at present restricted ;and I am inclined to think it should be removed from the Cancroideato the Grapsoidea. I am, however, unable at present to indicateits exact affinities.Mr. Haswell records it from Port Molle.04. Pilumnopeus serratifrons (Kmahaii).Two specimens are in the collection from Port Jackson (jVo. 104).The Eritish Museum contains specimens from Port Jackson{Cumimj), Port Phillip, Victoria (i^r. J. B. Kinahan), and the Australianseas, no definite locality {!Stutchhnry) ;also from New Zealand.In my ' Catalogue of the New -Zealand Crustacea,' p. 21 (1876),I have already pointed out the possible identity of Pilumnopeuscrassimanus, A. M.-Edwards, with P. serratifrons. I believe Mr.Haswell is right in regarding Heteropanope australiensis, Stimpson,as also synonymous with this species (Cat. p. 70).65. Ozius guttatus, var. speciosus.Ozius speciosus, Hilcjendorf, in Van der Decken^s Heisen in Ost-Afrika,iii. p. 74, pi. ii. lig. 1 (1809).An adult female is in the collection from Flinders Island, NortheastAustralia. Mr. Haswell records it from Port Denison and PortCurtis.To the same variety, as I think it must be designated, belongs anadult female in the British-Museum collection from Mauritius (LadyFrances Cole).In the typical form of Ozius guttatus, as described and figured byProf. Alph. Milne-Edwards in his <strong>Report</strong> on the Crustacean Eauna
