 Hab. — Western Port, San Remo, Portland (Maplestone). 

 Obs. — Mr. C. Hedley in the Proceedings of the Linnean 

 Society of New South Wales, vol. xxvii., pt. 4, pp. 597-599, 

 April, 1903, states that the identification of the South Australian 

 bivalve, by Professor R. Tate, as Mactra pura, Deshayes, is 

 erroneous (Tate, T.R.S. S.A., vol. ix., p. 83). The Mactra pura 

 of which Mr. Hedley gathered an example on the beach at Green 

 Island, off Cairns, Queensland, is stated to be a larger and flatter 

 species with a smooth dorsal area. Mr. Hedley has had South 

 Australian specimens compared with the type of M. abbreviata, 

 Lamarck, but identification with that species seems unsatisfac- 

 tory, even his correspondent preferring to regard our shell as a 

 distinct species. Mr. Hedley's conclusion to call the shell M. 

 abbreviata var., appears rather unfortunate, especially as the 

 figures given on plate 29, figures 1-3, do not appear to illustrate 

 the Victorian representatives of what is usually referred to here 

 as M. pura, Deshayes.
