NE refers to the Newport shelf, bounded on the east by Newport 

 Bay, on the north by Newport canyon, and on the west by the San Pedro 

 slope ; it extends oceanward as part of the San Pedro slope. 



LS refers to the Lasuen seamount, located beyond the outer end of 

 Newport canyon, in depths of 58 to 385 fms, and to Sixmile bank, ap- 

 proximately six miles northeast of Avalon, Santa Catalina Island. 



CL refers to the leeward side of Santa Catalina Island. A narrow, 

 long shore shelf borders the island, from East End at the southeast, to 

 West End at the northwest ; oceanward the shelf gives rise to the slope 

 which merges with the San Pedro basin (Hartman and Barnard, 1958, 

 1960). 



CW refers to the windward side of Santa Catalina Island. The nar- 

 row, long shore shelf extends westward as a slope, ofifshore rocks and 

 banks; it is dissected by the Catalina canyon, and in greater depths it 

 merges with the Catalina basin. 



Each of these areas has characteristic associations of organisms, for 

 which the details are explained below. 



An inshore area, in 2-5 fm depths, can be recognized as having some 

 species characteristic to it. Analyses for this area have been previously 

 published (California, 1965b, pp. 302-318).
