g250 COLLECTIONS PROM MELANESIA.must be referred to the variety cheverti, not only are the hepaticgranules entirely absent, but also the front has not the faintesttrace of trilobation.97. Leucosia craniolaris, var. laevimana. (Plate XXVI. fig. A.)I propose thus to designate, at least provisionally, a female specimenobtained in 10 fms. at Friday Island, Torres Straits (No. 153),which is distinguished from the very numerous examples ofL. craniolaris in the Museum collection by the absence of a seriesof granules on the inner margin of the palms of the chelipedes.The carapace is narrower than is usual in L. craniolaris, verypolished and shining, and has two white spots on either side of thegastric region. The notch in the anterior margin of the thoracicsinus is less distinct than is usual in L. craniolaris. A secondspecimen from Torres Straits, in the Museum collection, resemblesDr. Coppinger's example in its narrow rhomboidal carapace, but theinner margins of the chelipedes are distinctly granulated.Specimens of Leucosia craniolaris are in the British Museum fromTranquebar( OZcZ Collection) ; Ceylon (E. W. H. Holchwortli) ; Penan{Dr. Cantor); Borneo and Chinese seas {coll. H.M.S. Samarang^)','Formosa {Mattliew Diclcson) ; Hong-Kong {Dr. W. A. Harland andW. Stinipson).98. Myra carinata, Bell.Flinders, Clairmont, N.E. Australia. A fine male dredged in11 fms. (No. 108) seems to be referable to this species, which hasbeen recorded by Mr. Haswell * from Cape Grenville.Specimens are in the British-Museum collection from the Celebes,Macassar {coll. Dr. Bleeker), Philippines {Cuming), and Hong-Kong {Dr. W. A. Harland).These differ slightly among themselves in certain points, as e. g.the relative narrowness of the carapace, prominence of the innerand upper orbital angles, and length of the posterior spines, charactersthat may be of some importance ; but large series are needed todetermine with certainty the distinctions between the very variablespecies of this genus.99. Myra affinis, BeJl.Four specimens are referred here from Port Denison, 4 fms. (Nos.Ill, 122), first collection, and a larger female from Thursday Island,3-4 fms., second collection (No. 177), which, like the examples mentionedby Mr. Haswell from Cape Grenville and New South Wales,have a more or less distinct median longitudinal carina on thecarapace.Of M. affinis there are specimens in the British-Museum collectionfrom the Philippine Islands, Masbate, Zebu {Cuming), and fromthe Eastern seas {H.M.S. ' Samarang ') without special locality.* ' Catalogue,' p. 121 (1882).
