 Ericthonius hunteri: Stebbing, 1906, p. 673. — Enequist, 1950, pp. 314-345,

J. L. Barnard, 1962a, p. 63. 



Dahl (1946) and Enequist (1950) differ on the problem of the 

 identity of Ericthonius hunteri and E. difformis Milne Edwards; the 

 present specimens are closer to that figured by Sars (1895) as E. 

 hunteri than to E. difformis. 



Material. — cayucos: Phyllospadix--pe\vetiid grid, rare (9 per sq. 



m.). 



Distribution. — A subarctic-boreal species submerging to deep 

 waters of the shelf of southern California and probably with its 

 southern intertidal limits near Pt. Conception.

Alderman, 1936, p. 63.— J. L. Barnard, 1954a, p. 21. 



The specimens are of the Polycheria osborni kind. 



Material. — carmel: Phyllospadix-pelxetiid grid, rare (5 per sq. 

 m.); algal holdfasts, rare; coralline algae, rare; tunicates and sponges, 

 abundant, cayucos: Phyllospadix-yelx eiiid grid, scarce (23 per sq. m.) ; 

 soft polychaete tubes, moderately abundant; sponge, abundant; 

 Amaroucium sp., scarce to abundant; sponge, rare, hazard canyon: 

 sponge, abundant, corona del mar: tunicates and soft polychaete 

 tubes, scarce, la jolla: Phyllospadix-coraHine grid, scarce (16 per sq. 

 m.) ; sponge, rare. 



Distribution. — California, intertidal, burrowing in tunicates, 

 especially Amaroucium sp. If P. osborni is a phenotype or race of 

 P. antarctica then the species-complex is cosmopolitan.

 bular molar styliform; maxilla 1 lacking palp;- pereonites lacking
