';102COLLECTIONS FROM MELANESIA.33. Cardium, sp. jun.Hob. Port Curtis, Queensland {Coppinger).The two young shells from the above locality are closely allied toC unicolor, Sowerby.34. Chama divaricata.Reeve, Conch. Icon. fig. 20.Hah. Torres Straits, 10 fms., sand and shell bottom {Coi^pinger) ;island of Samar, Philippine Islands {Cuming).35. Chama pulcliella.Reeve, Conch. Icon. figs. 10 a, b.Hob. Port MoUe, Queensland, 12 fms. (Ooppinger) ; Cape Upstart(Juhes).The posterior brown ray is generally rather deeply sunken in thisspecies.36. Cardium maculosum, var.Wood, General Conch, p. 218, pi. 52. fig. 3 Reeve, Conch. Icon. fig. 76 ;var., Sorcerhy, Conch. 111. fig. G8.Cardium multistriatum, Sowcrhj, Conch. III. fig. 59.Cardium areuicolum, Reeve, Conch. Icon. fig. 78,Hah. Port MoUe, Queensland, 14 fms. (Coppinger) ; Ceylon(Holdsworth in Brit. Mus.) ; Molucca and Philippine Islands{Cuming); ? (TFooc?).A single shell from Port Molle, nearly an inch long, differs fromall specimens of this species which I have examined in having fewerribs, separated by broader intervening sulci, especially down theanterior side, and in being yellowish with less and paler blotchingwith reddish purple except within the valves, where, on account ofnot being concealed by a deposit of callus, it is especially vivid.The number of cost^e in this specimen is forty, and in typical examplesthere are usually about ten more. Cardium modestum ofPhilippi is also an allied species, with still fewer and stouter ribs,numbering altogether about thirty-iive or thirty-six. C. imdtistriatumwas originally described by Sowerby in the Proc. Zool. Soc.without a locality, and subsequently was stated by him to comefrom St. Elena, West Colombia ; but this, I am inclined to tliink,requires corroboration.37. Cardium multispinosum.Soiverhy ; Reeve, Conch. Icon. fig. 10; Riimer in Kiister's Con.-Cab.p. 07, pi. 12. figs. ],2.Hah. Port Molle, Queensland, 14 fms. {Coppinger) ; China (/.Reeves in Erit.
