MONOGRAPH 



OF THE GENUS 



L I T T R I N A. 



' It sees the ocean to its bosom clasp 



The rocks and sea-sand with the kiss of peace ; 

 It sees the w-ild winds lift it in their grasp, 

 And hold it up, and shake it like a fleece. 



' The startled waves leap over it ; the storm 



Smites it with all the scourges of the rain. 

 And steadily against its solid form 



Press the great shoulders of the hurricane." 



Longfellow.
