Ralfsia verrucosa, AG., {R. deusta, Berk.) For the first time in 

 America found by me at Little Nahant, October, 1871. Insig- 

 nificant looking, but probably not uncommon. 



Calliblepharis ciliata, KtJTZ. Collected by Professor Eaton, Mr, 

 Whitney, and myself, at Straightsmouth Island, off Cape Ann, 

 Massachusetts, September, 1871 ; not very abundant. Concep- 

 tacular fruit forming on some of the specimens.

 men sent to Harvey from Penobscot Bay, by Mr, J. Hooper. 



Geramium Rooperi, Harv. Straightsmouth Island. 



Fucus distichus, L. An alga, which I regard as undoubtedly this 

 species, I found growing in i^atches near high-water mark, at 

 Marblehead, Massachusetts, in May, 1871. I have seen grow- 

 ing, in considerable abundance at various stations of our 

 coast, a Fucus which I supposed at first to be an unripe state
