COMPLETE HARTMAN: POLYCHAETES FROM CALIFORNIA 53 



distally tapering smooth setae. Neuropodial setae are also in supra- and 

 subacicular fascicles and all of one kind; they number 5 to 10 in a 

 fascicle. The end of the shaft is ornamented with serrations and the 

 appendage is sharply curved and has serrations near the base of the 

 concave region (PI. 2, fig. 8). Setae in anterior segments and those in 

 superiormost position of parapodia have slightly longer appendages and 

 the serrated regions are more extensive than comparable ones in other 

 parts of neuropodia. 



Pholo'e is a small genus known for five species (see Hartman, 1959b, 

 p. 117). The type of the genus, P. minuta (Fabricius) from Greenland, 

 has been widely recorded from Arctic and boreal seas. It has a dorsum 

 broadly exposed and differs in other respects from P. glabra. Its several 

 subspecies or varieties include: P. minuta tecta Stimpson, from the Bay 

 of Fundy, Canada, to which P. minuta nans Zachs, from the Murman 

 coast, has been referred. P. minuta caeca Uschakov, from the Okhotsk 

 Sea, is diagnosed by Uschakov (1955, p. 165) and distinguished from 

 other species by details concerning the sizes of prostomial eyes and the 

 elytral processes. P. tuberculata Southern (1914, p. 57) from Irish seas, 

 is distinguished by having a conspicuous facial tubercle, the prostomium 

 has a deep median incision, and the ventrum is papillated. The elytra 

 leave the dorsum partly exposed. P. synophthalmia Claparede, from the 

 Mediterranean Sea, has eyes far forward on the prostomium, and P. 

 dorsipapillata Marenzeller, also from the Mediterranean Sea, has elytral 

 markings consisting of concentric rings. Diagnoses of these may be con- 

 sulted in Fauvel (1923, p. 119). P. glabra differs from these in its 

 prostomial proportions; elytra are nearly smooth and have simple mar- 

 ginal papillae ; neuropodial f alcigers are serrated along the distal end of 

 the shaft and the cutting edge of the appendage; and superior notosetae 

 are sharply geniculate and coarsely serrated along the curved region. 



Pholo'e glabra has been found most abundant off Newport Jetty light, 

 in 64 m, in green sandy silt, with temperature about 13.9°C. A bottom 

 sample measuring about 42 liters, yielded 112 individuals, together with 

 40 other species of polychaetes, numbering in all 358 specimens. Other 

 invertebrate animals included an ophiuroid, Amphiodia urtica (Lyman) 

 with nearly 600 specimens, and smaller crustaceans, especially ostracods 

 and amphipods, numbering more than 20 species and 300 specimens. 

 The most abundant polychaetes were humbrineris cruzensis Hartman, 

 Pectinaria calif orniensis Hartman, Cossura Candida Hartman, Prionospio 

 malmgreni Claparede, Nephtys ferruginea Hartman and Ancistrosyllis 

 tentaculata Treadwell. Other adjacent areas, where Pholo'e glabra
