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 Y{'inc]Cs History of the British Polyzoa, 1880; 

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