Table 29. — List of intertidal Amphipoda with southern affinities. They show- 

 evidence of disappearance from the intertidal at the northern end of the Mon- 

 terey-La Jolla coastal region. They are arranged subjectively in rank from the 

 most abundant to the least abundant in occurrence. Known or presumed 

 tropicopolitan species are marked with asterisks. Northernmost intertidal 

 records are enclosed in parentheses. Two sections are included: those species 

 found in the present survey and those taken from the literature.
