PORIFERA 



The serious difficulties attending the satisfactory identification of many of the sponges have 

 resulted in the accompanying list becoming in places a mere compilation. Large quantities 

 of material from Polperro, off the Dodman, and from Falmouth Bay have been examined from 

 time to time, but the rigorous exclusion of all records where there was any uncertainty as to 

 the identification has made the list in places simply an enumeration of the county specimens 

 mentioned by Bowerbank in his monograph. The classification and nomenclature is that given by 

 Dr. R. Hanitsch in his ' Revision of the generic nomenclature and classification in Bowerbank's 

 Spongiadae,' (Proc. Liverpool Bio!. Soc. viii).
