It is interesting to compare this list with that of the similar list recently 

 published for Plymouth,' a district where tlie Annelids have been very well 

 worked. The same five groups of Annelids have a total number of 153 

 species, including 144 Polychaetes, as against a total of 115 species, including 

 93 I'olychaetes from Dublin Bay. The deficit in the Dublin Bay list is 

 largely accounted for liy the almost complete absence of the southern or 

 Lusitauian group, whicli is very prominent at Plymouth. For instance, in 



' Journal Mar. Biol. Assoc, N.S., vol. vii., 1904, p. 219.
