No. 3. The Marine Algae of Santa Barbara County. 5 



Some of the Orders which should, perhaps, appear in the 

 list, have not been included, for the reason that their pres- 

 ence has not been noted or verified, but closer observation 

 will doubtless, in time, supply the deficiency. 



For the sake of uniformity in the nomenclature of the 

 Californian Alg-ae I have conformed mainly with the 

 arrangement of Dr. C. L. Anderson in his "California 

 Marine Algae," published in "Zoe" for October, 1891. 



Those portions not represented are, Class I. Cyano- 

 phyceae, (Blue Alg-ae), and the Orders Diatomaceae (K.), 

 and Squamarieae (K.). 



The Diatomaceae especially form a branch of study 

 with the microscope, and are not available for exhibition in 

 an ordinary herbarium. Nor do the others which have 

 been omitted lend themselves to the purpose of adding- to 

 the beauty of a collection. 



The writer desires to acknowledge the assistance of Dr. 

 W. G. Farlow, Professor of Cryptogamic Botany in 

 Harvard University; Professor W. A. Setchell of our State 

 University; and the late Professor Daniel C. Eaton, form- 

 erly of Yale University, in the verification of some of the 

 species. 



[Note. — For convenience of reference the Classes are numbered 

 from II. to IV. and the Orders are designated by the letters of the 

 alphabet (from C to T). This arrangement will be appreciated 

 when taken in connection with the Alphabetical Index of Genera 

 following- the list. 1
