120 REMARKS ON OLD-DESCRIBED AUSTRALIAN MOLLUSCA. 



Chili; Dr. Gould in United States Exploring Expedition, 1852, 

 ^ives New Zealand, and states that the "localities hitherto given, 

 Peru and Chili, are probably erroneous " ; Dr. E. v. Martens in 

 1873 says that "Gould corroborates Martyn's statement that it is 

 found also in New Zealand " ; Martyn never gave New Zealand 

 or New South Wales, as I have previously said ; Professor Hutton 

 in 1880 quotes New Zealand (Martyn and Gould), common in 

 Australia, and this is taken from Martens' Critical List of New 

 Zealand Mollusca, and again in 1884 he gives Wellington, New 

 Zealand, for it, and quotes Patella antipodum, E. A. Smith, as 

 being the same ; not having seen Mr. Smith's species, I will not 

 at present lump it with tramoserica. Mr. Pilsbry in Tryon's 

 Manual, Vol. xiii, p. 142, 1891, 1892, makes tramoserica and 

 antipodum one species ; the figure of the latter in the Zoology cf 

 the Voyage of H.M.S. Erebus and Terror, Mollusca, p. 4, pi. 1, 

 fig. 25, is very much like some of the many varieties of tramoserica, 

 and I doubt very much if Smith's species was ever found in New 

 Zealand. Dieff'enbach and others have made very grave errors in 

 their localities of Australian and New Zealand Mollusca ; even 

 authors in some of the recent manuals and monographs quote 

 strictly Australian species from New Zealand and New Ireland ; 

 some of them evidently take New Ireland as being near Australia 

 or a part of New Zealand. 



To sum up Helcionsiscus tramoserica is purely an Aufi- 

 tralian species there is not the least doubt, it having been found 

 in Tasmania, South Australia, Victoria, the whole coast line of 

 New South Wales, and into ISloreton Bay, Queensland ; and its 

 varieties are legion, and appear to have escaped the species-maker 

 of the Cuming school.
