HE alga which forms the subject of the present paper 
JL was discovered by Dr. Bornet in 1854 on some speci- 
mens of Cladophora pellucida , Ktitz., from Cherbourg, but it 
was not till long afterwards, when he had written the note on 
Melobesia ( Choreonema ) Thureti , Born., which appeared in the 
Etudes Phycologiques in 1878, that he made a careful ex- 
amination of it, and even then, being anxious to verify from 
the living plant certain details which the dried material did 
not show with sufficient clearness, he made no allusion to this 
interesting alga in the Etudes. Unfortunately since 1872 
Dr. Bornet has not met with the plant. 
In the meantime, while collecting at Torquay in 1885, I 
found what I believed to be an unknown alga, and, thinking it 
generically distinct from any described form, I placed it in 
my Herbarium under the name Erythrocelis Cladophorae , 
nov. gen. et sp., intending at some future date to publish an 
account of it ; but owing to a variety of circumstances this 
intention was never carried into effect. Last year, while at 
Puffin Island, I once more found the plant, and on showing it 
to my friends Mr. G. Murray and Mr. R. J. Gibson, with whom 
I was collecting, they strongly urged me to publish the notes 
I had prepared so long before. Erythrocelis Cladophorae ,
