Walney Island. Like the Boosebeck Scars it is almost 

 continuous with the shore and at low-water of spring 

 tides is nearly dry, but is covered to a depth of several feet 

 at high-water. The bottom is hard and consists of sand, 

 stones and Mussel shells, quite different from that at 

 Eoosebeck, consequently the Mussels have a much firmer 

 hold of the bottom and are not so easily washed off. 



The Mussels on this bed are numerous, large and. in 

 good condition, but are covered with barnacles. 



Fauna of the Scar. 

 Besides the Mussels, Buccinum, Purpura, Littorina 

 and Garcinus were also found on the bed. An examination 

 of the mud yielded thirteen species of Foraminifera 

 representing eight genera, five species of Ostracoda 

 representing four genera, and eight species of Copepoda 

 representing seven genera. The mud also contained 

 fragments of shells, spines of Spatangus, sponge spicules 

 and a few diatoms. The following is a list of the Ostra- 

 coda, Foraminifera and Copepoda : —
