498 STUDIES ON AUSTRALIAN MOLLUSCA, 



It was suggested by Smith* that P. gemmata should be trans- 

 ferred to Mylitta; and this classification was accepted by the 

 author of the species, f 



In arriving at the conclusion that M. incequalis, Dall, should 

 be reduced to a synonym of M. gemmata, Tate, I have been aided 

 by material kindly forwarded by Mr. E. H. Matthews, the finder 

 of M. incequalis. 



Venus scabra, Hanley. 



Reeve, Conch. Icon, xiv., Venus, pi. xxi., sp.97, 1863. 



This species appears not to have been recorded from N.S. Wales. 

 I have found it rather common from Sydney northwards, as dead 

 shells on beaches facing the ocean. 



Glycymeris flammea, Reeve. 



Reeve, Conch. Icon, i., Pectunculus, pi. ii., sp. 7, 1843. 



On the beach at Boyd town, Twofold Bay, N.S. Wales, I found 

 recently a valve of this species Not only is an addition thus 

 made to our local fauna, but the real habitat of the shell is now, 

 I believe, first announced. On doubtful grounds this species has 

 been attributed to New Zealand. Hutton reduces it to a synonym 

 of (P.) latico status, \ a classification at variance with Reeve's 

 figures of the two shells. Reeve has quoted the species as 

 described by himself in the P.Z.S., 1843, but I find no such 

 account in the volume indicated. 



The right of the orbicular arks to the name Glycymeris is 

 shown by Dall.§ 



Cytherea lamarckii, Gray. 



Romer, Monog. Venus, i. 1855, p. 97, pi. xxvi., f. 1. 



I found a few separate valves on the beach in Twofold Bay. 

 This species is, I think, an addition for N.S. Wales.
