'^—544 COLLECTIONS FROM THE WESTERN INDIAN OCEAN.along their inner margins, which are strongly dentated. Ambulatorylegs very hairy and pubescent, with the merus-joiut slightly compressed,but not dilated ; dactyli unarmed on the inferior marginsand terminating in a small corneous claw. Colour (in spirit)jiinkish ;hairs yellowish white. Length of carapace nearly 2 lines(4 millim.), breadth about 2| lines (5 millim.) ; length of thirdambulatory leg 4 lines (nearly 9 millim.).The single female in the collection was obtained at the Seychelles(4-12 fms.).The species described by A. M.-Edwards as Carclnoplax setosa,from New Caledonia *, resembles this form in many of its characters,but has a narrower, more arcuate front, and doutated antero-lateralmargins. To it I refer a specimen from the Fijis, Totoya {H.M.S.HeralcV), and perhaps two from the Philippines, 13ohol {Cuming),in the British-Museum collection,Geratoplax arcaata, described in the earlier part of this <strong>Report</strong>, isat once distinguished by the very differently shaped carapace, acuteedgedeye-peduncles, &c.61, Grapsus maculatus {Cateshy).Two adult females of this very common and widely distributedspecies are in the collection from African Island (No. 210). Tothe localities mentioned in my lleport in 1879 on the Transit-of-Venus Crustacea (t. c. p. 489), the following are to be added :Canaries, Teneriffe {Old Collection); Lanzarote {Rev. li. T. Lowe);Madagascar, Tamatave {Rev. Deans Cowan) ; Amboina {coll. Dr.BleeJcer) ; and Loyalty Islands, Lifu {Rev. S. J. Whitmee).This species, as hitherto recorded, ranges throughout the OrientalRegion southward to the Cape of Good Hope and New Zealand,eastward to the coasts of California and Peru, and occurs in theAtlantic Region at the Canary and Cape-Vcrd Islands and St.Helena, and on the American coasts and islands from Florida toPernambueo {cf. Kingsley, Proc. Acad. Nat. Sci. Philad. p. 193, 1880,who has shown that Catesby's designation maculatus must be usedfor this species instead of pictus of Latreille). I have never seenthe edition of Catesby's work published in 1771. In the originaland pre-Linnean edition (1743) the figure and description are sobad as to be scarcely recognizable.62.
