THE MARINE FAUNA OF THE HUMBER DISTRICT. 37 



"Notes on Polyzoa found at Cleethorpes," Vines (Nat, 

 Jan. 1892). 



With the exception of Cardium echinatum (listed with the 

 hope that search will be made for it on the Humber sands), 

 and possibly some of the polyzoa dredged off Hornsea, all 

 the species recorded here have been obtained alive. Many 

 others have been collected on the beach after storms, but it is 

 impossible to say how far these may have travelled, and 

 therefore it has been thought advisable that they should be 

 recorded separately.
