 pi. XX. fig. 18. 



Shell readily distinguished from all other Australian species 

 of Cardita here alluded to by its solidity, elevated umbonal 

 region, with correspondingly large hinge area, but especially by 

 its smooth, bold, radial costae, to the number of about eighteen ; 

 margins strongly crenulated. 



Dimensions. — Jleight 9 mm. ; length 9'5 mm. 



Form, and Loc. — Miocene : Muddy Creek, Victoria.

In his diagnosis the author remarks that this shell resembles 

 that of C. delicatula, Tate, but differs in not being so abruptly 

 truncate posteriorly, the umbones are placed a little farther backj 

 from the anterior margin ; it has fewer, broader, and much more 

 coarsely ornamented costae. It has also fewer and broader ribs thani 

 has C. tasmanica, Tate, whilst the interspaces are narrower, andj 

 the form of the two shells diff'ers. 



Dimensions. — Height 10*5mm. ; length 10 mm. 



Form, and Loc. — Eocene: Maude, Victoria.

Shell ovate, very inequilateral, truncated posteriorly ; surface 

 ornamented with about twenty-two radial costas, typically nodose 

 in the early growth of the shell, but becoming transversely 

 striated on nearing the margin ; lunule very small. 



The species name is here changed, the appellation intermedia 

 having been used for different kinds of Cardita, before Professor
