opposite, at the bottom of a well eighty feet deep he found in calcareous 

 grit two fossil Turbines figured at plate Supp. XLIX, fig. 1, 1, which

 site side of New Holland, and Lamarck gives New Zealand as its locality, 

 so that I think it probable that it may be found also in the vicinity of 

 Garden Island.

 at an advanced age.

The testacea, of which the following paper is a descriptive list, were 

 principally collected upon the Coast of South America; and upon my 

 arrival in England, were submitted to the examination of Mr. George 

 Sowerby; who, very obligingly, selected the undescribed species from
