other two were rare. In Carnarvon Bay it was found that 

 the form so abundant between the Mersey entrance and 

 Blackpool was quite absent, but the other two were present 

 in immense numbers. Off New Quay the abundant 

 member of the northern waters was also absent, and the 

 other two rare. The Copepoda were very unequally 

 distributed, large numbers were found off New Quay, a 

 fair quantity in Carnarvon Bay, and only a very few in 

 the North District. Fish eggs were only observed in the 

 collection from New Quay. The distinction between the 

 constituents of the plankton on the Welsh and Lancashire 

 coasts is very marked 



The following two results show the conditions 

 existing close to land and in the open sea. On May 22nd 

 one collection was taken off the entrance to the Bibble 

 and one close to the Liverpool North-West Lightship. 

 The latter is about seventeen miles S.W. from the former.

 were more numerous in the open sea than close inshore.
