There is practically no fishery of Palinurus vulgaris in Ireland. 

 It does not occur in anything like the same numbers as the Lob- 

 ster, and it is not held in great estimation as an article of food 

 in this country, whereas on the Continent it is greatly prized 

 and preferred by many to the Lobster itself.* 



Nephrops norvegicus, usually known in Ireland as the 

 *' prawQ," occurs in immense numbers in the northern part 

 of the Irish Sea, especially between the Isle of Man and the 

 coast of Louth and Down. It is from this district that the 

 greatest numbers are brought in by the trawlers. 



Many of the Reptantia described in this paper are of import- 

 ance as a source of food supply for fish of commercial value. 

 Off the south of Iceland Nephrops norvegicus occurs in such large 

 numbers that it forms the chief food of the cod. Some of the 

 burrowing species such as Callianassa Stehhingi, Axius stirhynckus, 

 and Upogebia deltaura are much more frequently found in the 

 stomach of bottom -living fishes than taken in the trawl.
