est width of 0.5 mm here. Thereafter the setigers become longer, but 
the width is only 0.8 mm. Rudiments of palps and gills are visible. 
Whereas the neuropodial bristles in the crowded section of the body 
are all about normal length, there are some threadlike setae in the 
notopodia. From about the thirteenth setiger these occur in notopodia 
and neuropodia, with a length of 0.5-0.6 mm. At the beginning of 
the exposed part, their width is about 4y, farther out only 3y; the 
thickness is about 1y here. These setae are “‘striated having a slight 
turn” as described by Moore (1903, p. 470); however, the scales ob- 
served on the large specimen from Japan could not be seen with 
1000 magnification in our material. 
Acicular spines occur in the species from the seventieth neuropod 
onward (Hartman, 1960). Our identification is based on the threadlike 
setae. 
Found at station 6 in May. New for Puget Sound. Previously 
recorded from Japan and California. 
Tharyx multifilis Moore 
Contrary to the original description by Moore (1909b), the anus of 
one complete specimen from Puget Sound is displaced dorsally by a 
very pronounced triangular ventral lip. This holds also for an in- 
dividual from Velero IV station 5027-57 off Pt. Fermin, kindly sent 
by Dr. O. Hartman. Thus the separation from this species of T. 
pacifica Annenkova continues to be doubtful as also pointed out by 
Chlebovich (1961); 7. pacifica has eyes, T. multiilis does not. The 
caudal ends of our two specimens are very slightly thickened (inflated), 
whereas Moore (1909b) and Hartman (1961) reported a slender taper- 
ing posterior end. 
A large portion of the intestinal contents of two specimens from 
two hauls at the fine-sand station 4 (mean diameter 0.10 mm) is made 
up of grains of 0.07-0.10 mm diameter, with a very few larger (0.15 
mm) particles present. Thus there seems to be only slight selection 
of particles when feeding.

There are several anterior and posterior fragments 1-2 cm long and 
0.38-0.5 mm wide. In all, there are at least 100 setigers. 
Description.—A pointed prostomium without eyes is followed by 
a 3-ringed achaetous region. The scars left by the broken-off palps at
