lML> COLLECTIONS FROM MELANESIA.. 



33. Cardiurn, sp. jun. 



Hab. Port Curtis, Queensland (Coppinger). 



The two young shells from the above locality are closely allied to 

 C. unicolor, Sowerhy. 



34. Chama divaricata. 

 Reeve, Conch. Icon. fig. 20. 



Hab. Torres Straits, 10 fins., sand and shell bottom (Coppinger) ; 

 island of Samar, Philippine Islands (Cuming). 



35. Chama pulchella. 

 Reeve, Conch. Icon. figs. 10 a, b. 



Hab. Port Molle, Queensland, 12 fms. (Coppinger); Cape Upstart 

 i Jukes). 



The posterior brown ray is generally rather deeply sunken in this 

 species. 



36. Cardiurn inaculosum, var. 



Wood, General Conch, p. 218, pi. 52. fig. 3 ; Reeve, Conch. Icon. fig. 76 ; 



var., Soiccrby, Conch. 111. fig. 63. 

 Cardiurn rnultistriatum, Sowerby, Conch. III. fig. 59. 

 Cardiurn areuicolum, Reeve, Conch. Icon. fig. 78. 



Hab. Port Molle, Queensland, 14 fms. (Coppinger); Ceylon 

 (Holdsworth in Brit. Mus.) : Molucca and Philippine Islands 

 (Cuming) ; ? (Wood). 



A single shell from Port Molle, nearly an inch long, differs from 

 all specimens of this species which I have examined in having fewer 

 ribs, sepai'ated by broader intervening sulci, especially down the 

 anterior side, and in being yellowish with less and paler blotching 

 with reddish purple except within the valves, where, on account of 

 not being concealed by a deposit of callus, it is especially vivid. 

 The number of costae in this specimen is forty, and in typical ex- 

 amples there are usually about ten more. Cardiurn modestum of 

 Philippi is also an allied species, with still fewer and stouter ribs, 

 numbering altogether about thirty-five or thirty-six. C. multi- 

 striatum was originally described by Sowerby in the Proc. Zool. Soc. 

 without a locality, and subsequently was stated by him to come 

 from. St. Elena, West Colombia; but this, I am inclined to think, 

 requires corroboration. 



37. Cardiurn multispinosum. 



Sowerby; Reev . Conch. Icon. fig. 10; Romer in Euster's Con.-Cab. 

 p. 67, pi. 12. figs. 1,2. 



Hab. Port Molle, Queensland, 14 fms. (Coppinger); China (/. 

 Reeves in Brit. Mus.) ; Philippine Islands (Cuming). 



The number of ribs in this species may vary from thirty-one to
