The Calappa Granulata is a genus of Crabs, common in Europe. They are called by the French migranes 

 and cogs de mer from their crests, and also crabes honteux, from their appearing to hide their legs under the 

 shell. They are of a pale rose color. 



The Hermit Crab is not so well protected as most of his tribe, since his tail is not covered with shell. 

 He is, therefore, wont to secure his undefended tail by inserting it into an empty shell, commonly that of 

 a whelk, and then walks about, dragging after him this curious appendant. Occasionally two of these 

 creatures covet the same shell, and then they have recourse to a duel. As the Crab grows larger, he must 

 have a new shell for his tail, and it is a curious spectacle to see him trying one after another, till he suits 

 himself. They annually visit the sea in large armies. They march straight on, and save a house or other 

 insurmountable barrier, nothing can stop them. 



The Common Cray-Fish abound in most of our rivers and brooks. They lodge in holes in the bank, 

 some times excavated by themselves, but oftener the abandoned abodes of water-rats. In rocky places, 

 they live under and among the stones. The usual mode of catching them is by lowering to the bottom a 

 net, baited with meat. Soon perceiving this, the fish come in numbers to the bait, when the net is sud- 

 denly hauled up, and the most of them secured. The flesh is esteemed a great delicacy. 



The Prawn so much resembles the Shrimp, that they are not readily distinguished from each other. 

 The main distinction between them is said to lie in the appearance of the toothed ridge running along the 

 back of the head, or rather the carapace. Brown, in its natural state, the Prawn assumes a pinkish hue 

 after boiling.
