NO. 2 HARTMAN : QUANTITATIVE SURVEY 373 



Catalina harbor 

 Catalina harbor was sampled in 4 to 100 fms. Shallower depths, in 

 0.5 to 10 fms, had been previously reported ( Reish, 1964) when 43 

 species of polychaetes were named, identical with those of the mainland 

 shelf, in comparable depths. 



1. Sta. 3586, in 4 fms. A snapper took about a liter of gray mud with 

 many small animals and a large nemertean, (jcrehratulus lineolatus. 

 Most abundant were Lumbrineris limicola and L. minima (together 

 260), Prionospio r/ia/mgnni (177), Paraoriis gracilis (40), Haploscolop- 

 los elongatus (35), and Tharyx nionilaris (23'^). Small crustaceans 

 were present as amphipods, tanaids and cumaceans. Echinoderms were 

 absent. 



Numbers of species and specimens totalled : 

 polychaetes 29 species, 600"^ specimens 



mollusks 5"^ lO'' 



crustaceans 5"^ 50'*" 



others 4 17 



Total: 43"^ species, 677"^ specimens 



2. Sta, 3585, in 23 fms. OPG took 1.89 cuft of gray mud with much 

 shelly and mucoid debris and many small animals. In addition to those 

 named in the chart, there were a sand-covered and a smooth anemone 

 (2), a nemertean in mucoid tube (4), Golfingia sp. (7), an echiuroid 

 (1), Dendrostotiia sp. (2), a phoronid (1) and Glottidia albida (14). 

 1 he most conspicuous were ophiuroids. Alost numerous were Tharyx 

 multifilis (56), Amphiodia urtica (38), Nephtys ferruginea (24), 

 () phiopholis longispina (21) and Amphipholis pugetana (20). Crusta- 

 ceans were present as amphipods (many) isopods, cumaceans, tanaids. 



Numbers of species and specimens totalled : 

 polychaetes 52 species, 289 specimens 



echinoderms 1 1 106 



mollusks 7 10 



crustaceans 10^ many 



others 7 39 



Total: 87^ species, 444^ specimens 



3. Sta. 3584, in 48 fms. OPG took 2.0 cuft of gray mud with shell 

 fragments, mucoid debris, and many animals. In addition to those listed 

 in the chart, there was a loose-pannicled sea pen (1), a nemertean (2), 

 amphipods (7), anthurid and gnathid isopods (2), a cumacean (1) and 

 an enteropneust (2). Largest species were the sea pen and Pista dis- 

 junct a, and most conspicuous was Aniphiura arcystata. Most abundant 

 were A inphiodia urtica (97) and Amphiura arcystata ( 14).
