The first part of the Marine Algae of the Pacific Coast of North 

 America, comprising an account of the Myxophyceae, or Blue-Green 

 Algae, is presented without introduction or explanation, pending the 

 publication of the other three parts which are in advanced preparation. 

 It is intended to issue with the completed volumes a statement as to 

 the principles followed, methods used, territory covered, sources of 

 information, material, etc., as well as to make acknowledgment to the 

 various authorities, students, and collaborators, who have been of the 

 greatest assistance in carrying out the long and laborious task.
