pores are present on setigers 3 and 4 (segments 6 and 7), contrary to 
Indian material (Fauvel, 1932). Nearly rectangular ventral shields 
occur through the thirteenth setiger. From the first setiger onward 
a wide glandular band is present ventrally and laterally behind the 
tori (without a torus being on the first, it is in the corresponding 
place). In the anterior part of the thorax it is laterally as broad as the 
tori but is hardly visible ventrally between the ventral shields. In 
the middle region of the thorax, glands occupy laterally all the space 
between the tori and the posterior border of the segments. Between 
the tori and the shields, they occupy one-half to over three-fourths 
of the length of the setigers. Ventrally, on the last four thoracic 
setigers, only the anterior one-third to one-half of the segments is 
free of glands 
All thoracic uncini have narrow, long, thin shafts (figs. 8g, h). In 
side view, the number of teeth above the rostrum appears to be five 
to six in anterior segments, and four to five in posterior segments of 
the thorax. The protuberance (‘‘x”’ in fig. 8h) on the lower anterior 
curvature of the posterior thoracic hooks is often less pronounced 
than shown.

There are three fairly well-preserved specimens from three hauls at 
station 3 in February. 
New for Puget Sound. Previously known in the North Pacific from 
the Bering Sea. 
Scionella japonica Moore 
FIGURES 82, 7 
The gills of our two specimens from station 7 agree with the descrip- 
tion by Moore (1908) and are like those of S. winogradow (Ushakov, 
1955, figs. 1483p, £), but not like those of S. japonica Berkeley and 
Berkeley (1952, fig. 176). Since the differences between these two 
species do not seem to be very clear, we give figures for the thoracal 
setae (figs. 8i, 7). Strong, long setae with very broad blades alternate 
with slightly more slender, shorter capillary bristles whose shafts are 
serrated above the short and narrow wings. Berkeley and Berkeley 
(1950) have pointed out that Moore figured only the larger setae.
