Chorizopora Bro?igniartii is rare on the Dublin coast, and 

 has only previously been recorded by Hassall, who described 

 Lepralia tenuis and L. assimilis from specimens he found in 

 Dublin Bay ; both these forms are C. Brongniartii, Aud. 



Cellepora Costazii has only once been previously recorded 

 from Dublin coast ; the specimens figured by Hassall in 

 Annals and Magazi?ie of Natural History, vol. vii., and 

 referred by him with doubt to C bimucronata, I,am., seem to be 

 C. Costazii, Aud., and were probably collected in Dublin Bay.
