Griffiths discovered in Torbay a plant possesing apparently the 

 leading or essential characters of the Norfolk one, but growing 

 in the open sea and always as a parasite on Bhodomenia palmata. 

 Meanwhile Agardh described a new Ectocarpus brackiatus, a native 

 of the Baltic, and conferred the name E. craciatus on the E. Bot. 

 species. The name brackiatus no doubt belongs to the Norfolk 

 plant, and if the Torbay individuals now figured and described, 

 and of which excellent specimens have been published in Mrs. 

 Wyatt's " Alga Danmoniensis " are essentially different, a new 

 name should be conferred on them ; and Agardh's E. brachiatus, 

 if it be not the same with E. splicer ophor us, Carm., might be 

 called E. Agardhianus.
