Report on the zoological collections made in the Indo-Pacific Ocean ...

:;CRrSTACEA. 54115 millim.), Tritliout exact locality (II.3I.S. Herald ' '), the carapacehas three brilliant jxatches of red—one on either side of the middleline on the frontal region, and one on the cardiac region reachingto the posterior margin. No trace of this coloration appears in thespecimen from Darros Island, but in other particulars they areclosely alike. This species, although rare, has a wide Oriental distribution.Stimpson's types were from the island of Ousima, andA. M.-Edwards records it from New Caledonia ; Hilgendorf (thoughdoubtfully) from Mozambique. By Kossmann {t. c. p. 47) thisspecies, as also T. crenata, is united with T. pripnna, Herbstpossibly therefore it occurs also on the coasts of the lied Sea, butthere is nothing to show whether Kossmann had among thq specimenshe refers to T. prymna any examples truly referable toT. picta, Stimpson.52. Lissocarcinus orbicularis, Dana.A small male from the Seychelles, 4-12 fms. (No. 194), seems tobe referable to this species ; it has the carapace very prettilymarked with circular spots of a dusky purplish colour with darkerborders. Specimens are in the British-Museum collection from tlioSamoa Islands {Rev. S. J. Whitmee) and Suwarrow Island (li.Hart). In these specimens, as in the one figured by Dana from theFijis, the purplish markings usually predomiiuite, so as sometimesnearly to cover the carapace.Of the type of the genus {L. polyhioidcs, Ad. & White), which hasa more elongated carapace with more prominent front and more distinctlydeveloped lateral frontal lobes, there are, besides the originalspecimens from Borneo, two examples from Ceylon {E. W. H.Holdsworth) in the Museum collection.53. Gelasimus annulipes, M.-Edw.A series of specimens was obtained on the beach at Mahe Island(No. 196).To the localities (whence the Museum possesses specimens) mentionedin 1879, in my <strong>Report</strong> on the Crustacea of the Transit-of-Venus Expedition, the following arc to be added :—Iliver Zambesi{H. War/horn) ; Port Natal, D'Urban Bay (Alfred E. Craven)Celebes {H.M.S. Samarang ' ') ; Batjan (coll. Dr. Bleel-er) ; andTimor Laut {H. 0. Forbes), received together with G. tetragonumand G. vocans.Kossmann (t. c. p. 53) records a variety (albhnamis) from the BedSea, which is apparently scarcely distinguishable from the typicalform of the species.54. Gelasimus dussumieri, M.-Edw.A specimen obtained at Mahc Island with the preceding speciesis referred here, although with some hesitation. G. dussumieri hasbeen hitherto a desideratum in the Museum collection.
