The open sea contained more Diatoms than the 

 territorial waters. A few Sagitta and Autolytus were 

 present in the open sea, but entirely absent inshore. The 

 eggs of plaice and bib were taken in the open sea only, 

 and those of cod, haddock and rockling inshore. 



Two collections taken six miles apart in the area, 

 sixteen miles W.N.W. of Piel, gave practically equal 

 results on March 13th, but the constituents of the 

 plankton were very different from what prevailed in the 

 open sea off Red Wharf Bay two weeks before.
