NO. 2 HARTMAN : QUANTITATIVE SURVEY 333 



SANTA CATALINA ISLAND, LEEWARD SIDE 



The leeward side of Santa Catalina Island (CL) has been sampled 

 on many occasions. Quantitative grab samples noted below were taken 

 along transects extending from East End, Avalon, Willow Cove, White 

 Cove-Long Point, Isthmus Cove, Howlands Landing, and West End, 

 leeward side. The details of kinds and abundance of animals are indi- 

 cated on the separate charts (below). 



East End 



1. Sta. 3611 (no. 259), in 30 fms. OPG took 0.56 cuft of green mud, 

 sand, strands of algae (Egregia) measuring to 1 1 feet long, and many 

 animals, especially amphipods, red-striped spirontocarid shrimps, poly- 

 chaetes, echinoderms and coelenterates. Polyclads, nemerteans and sipun- 

 culids were occasional. Encrusting bryozoans on kelps were varied. The 

 most conspicuous animals were O phiothrix spiculata, Chactopterus vario- 

 pi'datus and Platynereis hkanaliciilata ; most abundant were amphipods 

 and Capitella capitata subspp. Total number of species was more than 50. 



2. Sta. 5095 (near no. 259), in 40 fms. OPG took 0.81 cuft of f^ne 

 greenish brown sand. Largest individual was a red nemertean, Lepidas- 

 thenia ?virens, and most conspicuous was Sternaspis fossor. A mphiodin 

 urtica was most abundant, with 186 specimens. Other animals than those 

 shown on the chart included an anemone, three each of ceriantharians 

 and enteropneusts, and numerous small Pyrosoma. 



The number of species and specimens totalled : 



polychaetes 1 7* species, 1 1 6^ specimens 



echinoderms 6 226 



mollusks 6 13 



crustaceans 17 45 



others 5 9+ 



Total: 51* species, 409"^ specimens 



3. Sta. 2122 (no. 259), in 48 fms. OPG took 0.95 cuft of sandy 

 mud with dead Laqucus and other brachiopod shells, and living animals. 

 7 he largest were a ceriantharian anemone, and a nemertean. Crustaceans 

 were numerous, with ostracods, amphipods, cumaceans, isopods. 



4. Sta. 3613 (near no. 259), in 50 fms. OPG took 0.31 cuft of 

 glauconitic sand and white shelly debris, with many animals. Kelps were 

 absent and there was no large or conspicuous animal. Most abundant was 

 Nothria elegans, with 145* specimens, followed by Chactozonc setosa 

 with 68, and A mphiodia urtica with 50. The polychaetes w'ere followed
