POLYCHAETES FROM MONTEREY BAY. 

 BY RALPH V. CHAM BERLIN. 



The small collection of annelids listed below was made by 

 the writer in July of 1909 incidentally to other work. The 

 material was secured at or near Pacific Grove along shore or 

 at only moderate depths. Several of the records are new for 

 the locality and five of the species have seemingly not been 

 described before. The types of the new forms are deposited 

 in the Museum of Comparative Zoology at Cambridge.
