Mr. C. Hedley exhibited a species of Cassidula from Cooktown, 

 Queensland, and suggested that it approached nearer to Martj'n's 

 figure of C. nucleus than do forms from New Caledonia and other 

 localities which had hitherto been identified as that species. He 

 pointed out that the genus being unknown in the Eastern Pacific, 

 the habitat ' Otaheite ' ascribed to it by Martyn was undoubtedly 

 erroneous, and that if, like so many of Martyn's shells, it was 

 collected by Captain Cook, it wotdd not at all be improbable that it 

 had been procured when the Endeavour was repaired on Cooktown .
