inches long, of a delicate pink hue, rendered more 

 vivid by boiling. 



It is much in demand, being deservedly esteemed, 

 and is taken on the coasts of England, chiefly near 

 a shelving sandy shore : some, however, are found at 

 the mouths of rivers and even far up. Prawns swim 

 well, and in various directions, particularly when 

 alarmed. A species is found in the East Indies, 

 which is vastly larger than ours. The Prawn is 

 infested with a remarkable parasite, (Bopyrus,) which 

 fixes itself on the gills, causing a very perceptible 

 tumour on the outside of the shell. Under one of 

 these pests, were found by Risso, eight or nine hun- 

 dred living young ones. The fishermen in the 

 Channel, consider these animals as very young Soles 

 or Plaice. 



Passing by the remaining Orders of this division, 

 one of which contains the common Wood-louse 

 (Oniscus) and Button (Armadillo) of our gardens, and 

 to which the minute pest just alluded to belongs, 

 we pause an instant to notice the second section.
