fifth setiger but are barely noticeable. From Annenkova’s description 
(1922), B. sachalina is distinguished from B. ochotensis Annenkova 
mainly by the number of segments. Our specimens are intermediate 
in this respect. Both species have been described from the southern 
Sea of Okhotsk and occur also in the Bering Sea. 
Found only at station 2. Neither species has been found in the 
eastern Pacific before. 
Family OPHELIIDAE 
Travisia brevis Moore 
Our specimens, about 1.5 cm long, have 25 setigers followed by four 
achaetous segments, whereas Hartman (1961) stated that there are 
only two achaetous rings. Imajima (1963) has reported 24 setigers 
and four achaetous segments for specimens from the Okhotsk Sea, and 
Imajima (1964) has found 23 setigers in animals collected off Hokkaido. 
Family MALDANIDAE 
Isocirrus longiceps (Moore) 
Very numerous spherical (or slightly depressed) eggs about 250u 
in diameter were observed in November.

Incomplete mature specimens with up to 27 setigers are about 6 
em long and 1 mm thick. The longest animal is without the anterior 
three setigers and the rear end and must thus have had at least 30 
setigers; probably it had at least 34 setigers. 
The cephalic plate (figs. 8a, 6) has a low rim that dorsally is almost 
absent; there is no dorsal incision. The palpode is obtuse. Nuchal 
erooves are straight and one-half to three-fifths as long as the cephalic 
plate. The proboscis has conspicuous papillae that are triangular in 
side view. There are two to three slightly bent acicular spines (fig. 8c) 
in each parapodium of the first three setigers. These setigers are 
glandularized over their entire length. There are two bundles of 14-18 
limbate capillary setae each per ramus in the fifth and sixth setiger, 
with the fibrilles arranged as in figure 8d. The edges of the setae are 
not quite smooth (not shown in fig. 8d). There are six to seven short 
and long capillary setae each per ramus in the middle part of the body. 
The shorter ones are beset with hairs (fig. 8¢) up to the tip; the longer 
ones seem to carry hairs only in the proximal half. Thoracal unicni 
(14 per ramus in the fifth setiger) have one or two fewer secondary
