either coast of the Pacific Ocean as was previously supposed, but its 

 occurrence farther north may well be expected. 



Fucus ceranoides f. Harveyanus (Dec'ne) Kjellman, collected and 

 determined by De Alton Saunders at Pacific Grove, California, and 

 distributed in Tilden's American Algae, no. 339, is Hesperophycus 

 Harveyanus (Dec'ne) S. and G.. in Gardner, Variation in Nuclear 

 Extrusion, 1910, p. 127, and in Gardner, New Fucaceae, 1913, p. 317, 

 pis. 36. 37. 



In conclusion, it affords me much pleasure formally to acknowledge 

 my sincere gratitude to Professor W. A. Setchell for encouragement 

 and many valuable suggestions in the preparation of this work, to 

 Dr. M. A. Howe and Dr. Carl Skottsberg for prints of photographs 

 of type specimens, and to Mr. T. S. Brandegee for rendering the Latin 

 diagnoses of the new species and forms presented here.
