THE WONDERS OF THE SHORE. 139 
The bivalve! who has burrowed into the limestone 
knot (the softest part of the stone to his jaws, though 
the hardest to your chisel) is scandalized at having 
the soft mouths of his siphons so rudely touched, and 
taking your finger for some bothering Annelid, who 
wants to nibble him, is defending himself; shooting 
you, as naturalists do humming-birds, with water. 
Let him rest in peace; it will cost you ten minutes’ 
hard work, and much ditt, to extract him; but if you 
are fond of shells, secure one or two of those beau- 
tiful pink and straw-coloured scallops (Hinnites 
pusio, Plate X. fig. 1), who have gradually incorpo- 
rated the layers of their lower valve with the rough- 
nesses of the stone, destroying thereby the beautiful 
form which belongs to their race, but not their delicate 
colour. There are a few more bivalves too, adhering 
to the stone, and those rare ones, and two or three - 
delicate Mangeliz and Nasse? are trailing their 
eraceful spires up and down in search of food. That

* Plate VIII. represents the common Nassa, with the still more 
common Littorina littorea, their teeth-studded palates, and the free 
swimming young of the Nassa. (Vide Appendix.)
