In the present Catalogue, I am enabled, from my own collection, 

 and by the favor of a few friends, to give a catalogue of 428 

 American species, namely — 



Melanosperms ..... 93 



Rhodosperms .... . 181 



Chlorosperms . . . . .154 



Total . .428 



Professor Bailey's Catalogue . .172 



256 

 Being an increase of 256 species ; and as the subject commands 

 more attention, and the intelligence, industry, and energies of our 

 Naturalists are awakened, many are the additions which must be 

 discovered in our vast sea-boards. And when Dr. Harvey shall 

 have lain a solid foundation in his Neries Borealis Americanum ; 

 and when Professor Bailey shall devote himself to produce an 

 American Classification, aided, as he will be, by a number of tire- 

 less coadjutors, — then will the United States stand fairly represented 

 to the scientific world in her Marine Botany.
