1T7HILE I was out on the reef, that fine June morn- 

 VV ing, gathering specimens of the shell already 

 described and of other interesting kinds, the tide 

 began to come in and my investigations were some- 

 what disturbed. As the shore was a good way off, I 

 began to make my way across the rocks for the beach ; 

 but the water gained upon me, though at last my wet

 would beg my readers to never run serious risks in 

 collecting shells ; especially on the sea-coast keep a 

 sharp lookout for the waves and the tide, for more 

 than one person has been swept away from a lack of 

 watchfulness. 



Considerable space has been given to a consideration 

 of the first species, not because it is the most inter-

 explanation of its parts may serv^e as a guide in the 

 study of many other species. 



Authors differ very widely in the order they adopt 

 for the classification of shells ; but as this book is not
