Hah. Port Curtis, Queensland (Goppinger). 

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

 G. unieolor, Sowerhy.

Hah. Port MoUe, Queensland, 12 fms. (Goppinger}; Cape Upstart 

 (Jukes). 



The posferior brown ray is generally rather deeply sunken in this 

 species.

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

 aU specimens of this species which I have exatained in having fewer 

 ribSj separated 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 caUus, it is especially vivid. 

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

 amples there are usually about ten nlore. Oardium modestwm of 

 PhUippi is also an allied species, with stiU fewer and stouter ribs, 

 numbering altogether about thirty-five or thirty-six. G. 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 odrtoboration. 



37. Cardium mnltispinosxun. 



Sowerby; Seeve, Conch. Icon. fig. 10; Somer in Eister's Con.-Cah, 

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



Eah. Port MoUe, Queensland, 14 fms. (Goppinger); China (J. 

 Beeves in Brit. Mus.) ; Philippine Islands (Guming). 

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