SOME NEW LOCALITIES FOR MARINE ALGAE. 
BY J. ADAMS, M.A. 
Some time ago I submitted a parcel of Algae collected 
during several years from various parts of Ireland, to Mr. 
A. D. Cotton, of Kew, who kindly named the rarer species 
for me. Among these there appear to be three not 
previously recorded from Ireland, namely, Enter omorpha 
crinita, J. Ag. ; Ascocyclus sphaerophorus, Sauv. ; and 
Calluhamnton scopulorum, Ag.^ Particulars concerning the 
distribufion of some commoner species are also given, as. some 
of these though common on several parts of the coast are 
entirely absent from several counties.
