COMPLETE HARTMAN: POLYCHAETES FROM CALIFORNIA 91 



Hooded hooks are present in both notopodia and neuropodia of pos- 

 terior segments. A median parapodium has 6 superior long, slender, 

 distally pointed setae, 7 pairs of more inferior setae, each set with an 

 acicular, distally entire, or bifid hooded hook, and a long pointed seta. 

 The corresponding neuropodia have 13 pairs of acicular curved hooded 

 hooks, and an equal number of long, slender capillary setae like those in 

 notopodia but somewhat slenderer. The first three ventralmost setae are 

 the longest ; they are directed ventrolateral^. 



The subspecies differs from the stem, Nerine foliosa, in that neuro- 

 podial hooks are first present at about segment 27 instead of 58-60, and 

 notopodial hooks are present at about segment 30, whereas in the stem 

 they occur from segment 60-67. Branchiae are completely bordered by 

 the postsetal lamella in the stem species, whereas they have a short free 

 tip in the subspecies. The hooded hooks are very similar in both forms. 



Nerine foliosa occidentals has been taken from silty sediments 1.9 

 mi west of Newport Beach, 5.4 mi from Point Fermin light, and 16.5 

 mi from Santa Barbara light, in 11 to 23 fms. It is associated with a 

 diversified polychaete fauna including other spionids, Laonice cirrata 

 (Sars), Prionospio pinnata Ehlers, P. malmgreni Claparede, Spiophanes 

 bombyx (Claparede), S. missionensis Hartman, Tharyx tesselata Hart- 

 man and other cirratulids, and numerous other polychaetes numbering 

 76 species and 600 specimens from a grab sample measuring 0.63 cuft 

 of gray black sand, in 11 fm, black sand.

This is a small species; total length is about 15 mi; width 0.9 mm; 

 segments number 61. The prostomium is longer than wide, rounded in 

 front (PI. 12, fig. 1) and has 4 eyes at its posterior end; they are in 

 crescentic arrangement with the anterior pair widest apart, and the 

 posterior eyes located between the palpal bases. A pair of dark pigment 

 patches is present at the frontal bases of the palpi, and a similar pair 

 of spots on the peristomium, in front of the first parapodial segment. 

 The ventral side of the body is pale, has black, paired narrow bars in 

 segmental grooves, mainly between segments 3/4 to about 16/17. On
