COMPLETE HARTMAN: POLYCHAETES FROM CALIFORNIA 77 



prostomial eyes which are also dark and have pale lenses. Prostomial 

 antennae, peristomial cirri and dorsal cirri are cirriform and lack articu- 

 lations. Dorsal cirri are alternately long and short. 



Hesperalia calif orniensis Chamberlin (1919, p. 9) from Laguna 

 Beach, California, is here considered identical. It was characterized by 

 having antennae and dorsal cirri articulated, but this is here interpreted 

 as wrinkling due to preservation. In other respects there is complete 

 agreement with Odontosyllis phosphorea Moore. 



This species is known more extensively from western Canada to 

 southern California, in littoral depths, associated with rocky substrata. 



Odontosyllis spp. 



Another species of the genus was taken off Palos Verdes, California, 

 (Sta. 3050) washed out of a kelp holdfast from a colony of Chaetopterus 

 variopedatus. The dorsum is deep purple, and dorsal and ventral cirri 

 are ivory white. Parapodia are provided with up to 15-20 composite 

 falcigers in which the distal end of the shaft is oblique, thick, and sup- 

 ports a falcigerous appendage with a sharp triangular tooth near its basal 

 cutting edge. Acicula are yellow, distally truncate and hammer-shaped. 



Still another species of the same genus was taken in a grab sample 

 10 miles out from Point Loma, in 17 meters, in rocky habitat with 

 Ophiothrix and Strongylocentrotus spp. (echinoderms). This one has 

 5 dark, longitudinal stripes extending throughout the length of the body ; 

 a large, semicircular nuchal flap and the rest of the body, including 

 cirri, are pale. Composite falcigers have an appendage that is bifid, 

 with the accessory tooth located near the middle of the cutting edge, 

 nearer the distal fang. Acicula are yellow, distally somewhat clubbed, 

 and terminate in a constricted tip. 



Genus Typosyllis Langerhans, 1879 

 Type T. krohnii (Ehlers) 1864 



The most frequently encountered member of the SYLLINAE in 

 grab samples taken from shallow littoral benthos of southern California 

 is a species of Typosyllis, approaching T. armillaris (Miiller) (see 

 below).
