Table 27. — List of intertidal Amphipoda which are ubiquitous in the Monterey- 

 La Jolla portion of California. They are arranged subjectively in rank from 

 the most abundant to the least abundant in occurrence. Cosmopolitan species 

 are marked with two asterisks, and those species common to the northwestern 

 Pacific Ocean are marked with one asterisk.

Table 28. — List of intertidal Amphipoda with northern affinities. They show 

 evidence of disappearance from the intertidal at the southern 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. Species which possibly 

 are amphi- Pacific-boreal in distribution are marked with asterisks. Southernmost 

 intertidal records are enclosed in parentheses. Two sections are included: 

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