Notes on Distribution. — The species of marine algae marked * 

 are generally distributed in warm waters. The species marked f are 

 limited to the West Indian and Florida region. "Liagora elongata 

 and Cystoseira myrica are characteristic Red Sea plants; Liagora 

 Cheyneana is an Australian species. Liagora elongata and Cymopolia 

 Mexicana are, I think, new to the West Indian region, although it 

 is now considered rather doubtful whether the last-named species 

 k distiact horn Cbarbata." (F. S. Collins.)
