Atlantic coasts of America and Europe, which have since 

 then been assigned to their proper places as distinct species. 

 Others were given names which are not now recognized or 

 used. Names were given which are now considered as 

 synonyms. Several new species have been discovered and 

 added to the list. 



In order to assist students and collectors I have pre- 

 pared the following list, which is not to be considered as 

 complete; the names of such species are given as I have 

 been able to verify by specimens in my herbarium, or such 

 as are credited by competent authority. 



A few whose identity has not been satisf actorily de- 

 termined are preceded by an (?), and a few which have 

 been credited to us by other collectors have the names of 

 said collectors, or writers inclosed in brackets. 



This list will, perhaps, serve as a basis upon which 

 future students may enlarge, as other species are discovered 

 or noted. It will also serve as a convenient check list. 



Collectors generally gather the more striking and 

 beautiful of the species, leaving the larger and coarser 

 plants, and the minute species unnoticed, or, dismiss them 

 with a casual glance. 



The small species which appear insignificant to the 

 unaided eye are neglected, or left to be worked up by those 

 who make a careful microscopic study of the same. The 

 latter students are however, fully compensated for their 

 labor by the enjoyment of the exquisite beaut} 7 and won- 

 derful detail of structure of the minute forms presented to 

 their observation. 



The well-know influence of the peculiar conformation 

 of our coast line, whereby Point Concepcion forms a more 

 or less masked line of demarkation between the flora and 

 fauna of the North and the South, may explain the absence 

 from the list of some of the more northerly and coarser 

 species known as "Sea Weeds." It is however probable 

 that some of them may be found on the Islands of San 

 Miguel and Santa Rosa, where the prevailing winds render 

 the rock-bound coast and outlying islets inaccessable during 

 the greater portion of the year.
