account, but Hanley* later ascribed the species to New South 

 Wales, a statement which though accurate at the time, ceased to 

 be so after the political separation of Queensland. 



Reeve introduced confusion by describing this shell firstly! as 

 Pinna serra, presumably a new species, from Moreton Bay, and 

 secondlyl as P. serrata Solander, from the West Indies. The 

 species is not included in any West Indian catalogue to which I 

 have access. 



This mistake dislocated the literary history of the species. 

 Subsequent authors, von Martens,§ Smith, || and Clessin^ lost 

 si<^ht of G. B. Sowerby's original name, and have used P. serrata 

 Reeve, for the species. 



The shell seems to be a rare one. The locality of Moreton Bay 

 has been recently confirmed by Mr. G. Gross, and I have seen an 

 example from Keppel Bay. 



Standella nicobarica Gmelin. 



The first regular binomial given to this species was that of 

 Mactra nicobarica, which Gmelin** founded on an illustration 

 by Chemnitz. ft Several subsequent writers appeared to have 

 confused this Oriental species with the European S. rugosa 

 Gmelin. But Reeve figured Gmelin's M. nicohaj'ica under the 

 title of Mactra cegyptiaca. X % For a clue to this complication I am 

 indebted to a reference by Dr. Dall.§§ 



The only Australian record of this species is by Angas,|||| who 

 reported it, under the name of Merope cbgyptiaca, from Lake 

 Macquarie, N.S.W^. I can add that it extends thence north- 

 ward along the whole Queensland coast.
