SANTA CATALINA ISLAND, WINDWARD SIDE 



The grab was lowered along transect lines extending oceanward, 

 from the outer side of West End, Ribbon Rock (see Map 2), Catalina 

 harbor, Farnsworth bank, China Point to Salta Verde point, and Pali- 

 sades. Analyses disclosed changes in faunal composition by place and 

 depth. Many species were found which are unknown on the leeward 

 side of the island. The finding of a conspicuous bryozoan fauna on 

 Farnsworth bank, and a large population of the lingulate brachiopod at 

 Palisades were noteworthy. 



West End 



1. Sta. 3577, in 15 fnis. A snapper sampler took black debris with 

 large tubes of Chactopterus variopedatus and many associated animals, 

 resembling those at White Cove, SCI, in comparable depths. 



2. Sta. 3576, in 36 fms. OPG took 0.37 cuft of shelly sand with 

 broken shells, chiefly MytUiis and other shelf-mollusks, also bryozoan 

 clusters, fragmented tubes of Telepsavus costariun and Phyllochnetop- 

 terus proUfica. In addition to the species named in the chart, there were 

 a small ceriantharian (5), an anemone covered with coarse, black sand 

 (12), a long ribbonlike polyclad (1), a nemertean (3), a slender sipun- 

 culid (12), a phoronid in coarse, sand-covered tube (12), amphipods of 

 several kinds (many), an anthurid isopod (several), a tanaid (7), an 

 ostracod (7), a cumacean (2), a dromiid crab (2), and Glottidia albida 

 (5). 7 he largest species was Glycera americana; none was conspicuously 

 abundant. Total numbers were estimated at more than 80 species and 

 S75 specimens. 



3. Sta. 3575, in 44 fms. OPG took 0.25 cuft of green shelly sand 

 with rock chips. The sample contained many small to very small animals, 

 like those on the leeward side of the island. Rocks had attached Fer/nili- 

 opsis and tubes of Pista. Polychaetes, echinoderms, mollusks and small 

 crustaceans were diversified and represented by immature individuals. 



4. Sta. 3573, in 88 fms. OPG took 0.31 cuft of glauconitic white 

 sand, with echinoid ( ^Lytechinus) spines, foraminiferans and many 

 small animals, like those of the leeward side of the island. None was 

 large ; most abundant species were Nothria stiginaiis ( 140) , Chloeia pin- 

 nata (52) zw^ Amphiodia digitata (45).
