This author obferves, that in a young ftate it has the 

 appearance of a winged infeft, and fports in its watery 

 element with all the livelinefs of a butterfly, and formed 

 a pleafing obje£l when kept alive in a glafs of fea- water. 



We have found this fpecies in the harbour at Poole ; 

 and on the fhore near Southampton, it is by no means un- 

 common between that town and the Itchin, where the 

 fifhermen call them fea-fnails, and affured us they were 

 very lively in the water in warm weather, and fometimes 

 quitted their (hells ; this circumftance however is to be 

 doubted, Chemnitz has defcribed and figured it very 

 well, and fpeaks of it as a Dutch and Norwegian fliell : he 

 has alfo given another from Ceylon, which feems to differ 

 only in being of fuperior fize.
