SUBMARINE CANYONS OF SOUTHERN CALIFORNIA 

 POLYCHAETOUS ANNELIDS 



By Olga Hartman 



This systematic report lists the polychaetes recovered from the sub- 

 marine canyons of southern California which are given in the 

 ANALYSES (see Part 2). Each is named with its occurrence by canyon, 

 depth in meters and numbers of individuals in a sample. More complete 

 bibliographic citations may be consulted in reports by Hartman (1959- 

 1961). I am indebted to Mr. Anker Petersen for the preparation 

 of the illustrations. 



The names and locations of canyons may be consulted in Part 2.
