Announcement 



The Puget Sound Marine Station Publications appear at irregular in- 

 tervals as the articles are ready for publication. The papers are numbered 

 consecutively, and paged consecutively until a volume is completed. The 

 articles are chiefly on marine animals and plants, and it is expected that 

 they will be the direct results of the work at the Station. The Publications 

 are offered in exchange for the publications of universities, learned institu- 

 tions and societies, and libraries. 



The editorial staff is composed of the following: 



T. C. Frye, University of Washington. 

 H. S. Erode, Whitman College. 

 Trevor Kincaid, University of Washington. 

 W. J. Baumgartner, University of Kansas. 

 Albert Sweetzer, University of Oregon.
