Table 25. — La Jolla, California, November 11-13, 1962, 5 non-quantitative 

 wash-samples of the short-tufted algal platform, 45-0-1, 0-2, T-l, W-3, 

 W-4, the most abundant species, with total number of individuals. 



Hyale rubra freguens, 1,005; Elasmopus rapax serricatus, 202; Photis sp., juvs., 138; Microjassa litotes, 115; 

 Ampithoe poller, 112; Microdeutopus schmitti, 91; Aoroides columbiae, 87; Elasmopus antennatus, 82; Am- 

 philochus litoralis, 43. 



Table 26.' — Locality comparison of the dominant Amphipoda in seven grids of 

 the Phyllospadix-pelvetiid zone of California. Numbers represent individuals 

 per square meter. Those species marked with asterisks have unidentified 

 juveniles included in proportion to adult representation in the samples. Itali- 

 cized numbers denote species dominating the particular grid. The gridwork 

 at Hazard Canyon is located on a platform of algal turf and not in the Phyllo- 

 spacfe-pelvetiid zone. The species are arranged in rank according to the totals 

 of the frequencies in the seven grids. Eight other species of high frequency 

 are listed terminally and are numbered by rank in sequence with the dominant 

 species. None of the eight terminal species is a major dominant in any of the 

 seven grids but the cumulative frequencies of several exceed the frequencies 

 of a few of the dominant species.
