224 ROBERTSON [S^^] 



The only work which has heretofore been published on the 

 Bryozoa of Alaska waters is that of Mr. Hincks in the report 

 on the Polyzoa of Queen Charlotte Islands ('82-84). Many 

 species are common to Alaska, Queen Charlotte Islands, Puget 

 Sound, and California, and under local distribution I have in- 

 cluded all the localities on the western coast of North America, 

 where I know, either from personal knowledge, or on the au- 

 thority of others, that a particular species exists.
