BENTHIC AMPHIPODA 

 OF MONTEREY BAY, CALIFORNIA 



By J. Laurens Barnard 



Associate Curator, Division of Crustacea 



The fauna of benthic subinter tidal Amphipoda in Monterey Bay, 

 California is compared to that of southern California south of Point 

 Conception. This study of northern Amphipoda complements a 

 study of southern Amphipoda of Baja California (Barnard, 1964a). 

 The two surveys have been conducted in order to determine the 

 affinities of various Amphipoda of southern California. 



The extrinsic distributions of southern California Amphipoda are 

 poorly known except for those species from Baja California reported 

 by Shoemaker (1925, 1942), Barnard (1964a), and those from Oregon, 

 Washington, and British Columbia reported by Caiman (1898), 

 Walker (1898), Thorsteinson (1941), Barnard (1954), Bousfield 

 (1958), and Mills (1961, 1962). Most of the cited papers have 

 treated only intertidal species. Although Monterey Bay has not 

 been considered to be a typical cold-temperate area, the present 

 analyses indicate the cold-temperate character of several California 

 Amphipoda. 



I am indebted to Dr. R. E. Stevenson of Florida State University, 

 formerly of the Allan Hancock Foundation, who directed the Cali- 

 fornia State Water Pollution Control Board survey of California.
