:CRUSTACEA. 265the dactyli well developed and impinging against the producedscabrous infero-distal lobe of the preceding joint. The postabdomen(in the female) has on its left side three appendages, articulatedwith as many membranaceous dorsal plates, and each terminatingin four filaments or tiagella, which are clothed with long hairs. Theuropods on one side are imperfect, their rami ^e margined withrather long hairs ; the segment with which they are articulated hasa longitudinal groove on its dorsal surface. The coloration (whichis probably faded in both the specimens examined) is yellowish orwhitish, with very faint pink reticulations in the larger specimen ;the chelae are pink, the eye-peduncles bordered on the sides withbroad longitudinal bands' of brownish pink; the under and innersurfaces of the last two joints of the second and third legs are ofthe same colour. The length of the carapace (in the larger specimen)is about 1 inch 5 lines (37millim.), the length of the third(right) leg exceeds 3| inches (90 millim.) ; but the specimen beingdried, its exact dimensions cannot be given.Of this species a rather small adult female was taken in theArafura Sea, 32-36 fms. (No. 160). A much larger female, in mutilatedcondition, wanting the postabdomen, is among the Banksianspecimens in the British-Museum collection, from which the descriptionis mainly taken.This species resembles Clibanarius, and differs from most speciesof Fagurus in the subequal spinulose chelipedes ; in the structureof the ophthalmic segment of the eyes, the absence of a rostrum,and in other points it is a true Pagurus. In P. platytliorax, Stm., aspecies with equal chelipedes, the chelae and legs are not spinulose.The Pagurus minutus, Hess (vide Haswell, Cat. p. 156), fromSydney, is too briefly described for certain identification, but seemsto be distinguished from P. rubrovittatus by the shorter antennalappendages and tubercidated non-spinuliferous chelipedes.8.

Another specimen, presenting a preciselysimilar system of coloration, is in the British-Museum collectionf om Shark ^ay {F. M. Pagner, H.M.S. Herald '').These specWens agree with the figure of Quoy and Gaimard, anddiff'er from the sjOimens referred to C. vulgaris in the collection ofthe British Museum, in having the carapace (as well as the ambulatorylegs) marked with longitudinal pale lines bordered with redin the specimens referred to P. vulgaris this coloration does not existupon the carapace; the eye-peduncles are somewhat longer and
