POLYZOA 



The following list is based on personal observations, but chiefly on Mr. Alder's catalogue 

 and its supplement (Trans. Tyneside Nat. Field Club, 1857 and 1863). The nomenclature 

 used there has been corrected to that employed in Hinck's/firtary of the British Polyzoa, 1880; 

 although that nomenclature is at the present time undergoing much modification.
