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

;CRUSTACEA. 533Transit-of-Yenxis Expedition at Eodriguez, I have already alluded tothe geographical distribution of this verj' variable species *.The specimens in the Museum collection are from Eodriguez{H. H. Slater) ; Eed Sea, El Tor (Major MacDonald), and Gulf ofSuez (R. J\IcAndrew and J. K. Lord) ; Eiji Islands {E.M.S.'Herald');Samoa Islands (Rev. S. J. Whitmee).The variety meJanodactylus is usually less pubescent than thetypical C. andreossii, and the lower part of the outer surface ofthe larger chelipede is usually, but not invariably, destitute ofgranules or tubercles.A male and female, from the Dcedalus Shoal, Red Sea (Lt.-Col.Pkujfair), which may be designated C. andreossii, var. quadrilohalHs,are distinguished from all other specimens of the genus Ihave seen by having the front armed with four very distinct equaland equidistant rounded lobes or teeth. In this variety the carapaceis very distinctly granulated on the protogastric and hepatic regions,and the chelae tuberculated on the whole of their outer surface, thetubercles being very hii'ge, rounded, and granulated on and near theupper margin ; the fingers were dark- coloured.In both specimens there is a red spot on the gastric, cardiac, andbranchial regions of the carapace. It may perhaps prove to bespecifically distinct.33. Actumnus setifer (De Haan).Of this species, upon whose synonymy and distribution I haveremarked on p. 225, a male and three females were collected at theSeychelles, 4-12 fms. (No. 194), a small female at He des Neufs,15 fms. (No. 187), and two males and a female at Providence Island,17 fms. (No. 217).The length of the carapace of the smallest ova-bearing female isless than 3 lines (6 millim.).Actunmus miliaris, A. Milne-Edwards f, an allied species, also fromthe Sevchelles, seems to be well distiuguislied by the much less prominentand acute lobes of the antero-lateral margins, and by thedeflexed index or immobile finger of the larger chelipede.34.

I'hilad. p. 37 (1858) ;nom.genericumjjreeoc.A male and female were obtained on the beach at Poivre Island(No. 198).In the British-Museum collection is a male from the Eiji Islands,Totoya (U.M.S. ' Herald^). Specimens from the Keeling or CocoaIslands (Lt.-Col. Burnahy) possibly belong to a different species, asthey have the antero-lateral margins of ihe carapace less distinctly* Phil.
