Pinna inerniis, Tate, 1886, Trans. R. Soc-. S. Austr., vol. IX., 

 p. 71, pi. IV., Fig. 5. 



Prof. Tate records this species from St., Vincent's Gulf, and 

 generally from Eucla to the s:outh-east coast of South Australia. It 

 is found "partially buried vertically in mud or sand in a few 

 fathoms water." 



In some respects the fossil shell resembles the earlier portion of 

 P. virgata, Menke, a West Australian living form, but is distin- 

 guished by the feeble radial ridges, which in the living species are 

 very distinct.
