PUGET SOUND MARINE STATION 

 PUBLICATIONS 



Mail addressed to the Puget Sound Marine Station often is confused 

 with that for the United States Navy Yard or for the United States Naval 

 Training Station. For that reason it is necessary to change slightly the 

 name of the series. Future numbers will therefore appear as the Publica- 

 tions of Puget Sound Biological Station of the University of Washington.
