PACIFIC SCIENCE, Vol. II, January, 1948 
patch; area IV has about 25 cones in a crescent, 
the largest ones on the side toward area III. On 
the oral ring, area V has none, area VI has seven 
or eight small circular cones; areas VII and VIII 
(continuous) have seven larger pointed cones 
in a row on the maxillary side and about six 
to eight irregular rows of many tiny cones; 
those on the oral side are gradually smaller. The 
largest cones are on areas II and IV and those 
on the maxillary side of VII. 
The proportions of dorsal ligule to other 
parts of the parapodium, especially in far pos¬ 
terior parapodia, differ somewhat from those 
described (Malmgren, 1867) for individuals 
from the type locality, in that in the present 
case the dorsal ligule is relatively larger, but in 
other respects there is agreement. 
Originally described from Greenland, this 
species has been reported from both sides of 
the Atlantic. The present record is Canoe Bay, 
25 to 40 fm.

This species is well known in the north 
Pacific, from Alaska south to central California. 
The present records are from shore stations in 
southwestern Alaska.

Mitrofania Bay (2 male epitokes). 
This species is apparently common through¬ 
out littoral areas of the northeast Pacific. In 
some individuals the parapodial ligules are 
opaque white, in others fuscous to dusky black, 
as typical for N. neonigripes Hartman (1936). 
In all, however, the proboscidial parts are much 
alike and the proportions of parapodia are 
similar. Homogomph falcigerous notosetae are 
present from a premedian segment and are 
continued posteriorly to the end. In the two 
male epitokous individuals from Mitrofania 
Bay, there are only 16, instead of 17, anterior 
setigerous segments, and natatory parapodia are 
continued posteriorly to the end. I am now 
inclined to regard N. neonigripes Hartman 
(193 6b: 471-472) from California as a variety 
of N. pelagica, if not merely a color phase. In 
living individuals the dark parapodial ligules of 
the latter are striking but they tend to fade out 
in fixed specimens. 
N. pelagica has been widely reported from 
all seas. 
Nereis neoneanthes new species 
Fig. 7 a-d. 
Collections. Station C 150-41 (1), western 
Oregon (1). 
A single incomplete individual was removed 
from within a sabellid tube; it is over 100 mm. 
long but the body is soft and slightly macerated. 
There are over 131 segments; the body is long 
and slender. The prostomium has four circular, 
embedded eyes in the usual arrangement. The 
paired palpi have long bases that project for¬ 
ward beyond the paired antennae; their pal- 
podes are subspherical. The peristomial ten¬ 
tacles are short, simple, and tapering; the longest 
reaches back to about the third setigerous seg¬ 
ment, the shortest is almost twice as long as a 
prostomial antenna. The peristomial ring is 
nearly twice as long as the first setigerous ring. 
The proboscis is unique in having many 
paragnaths. The oral ring has many rounded 
paragnaths, all similar in appearance but those 
on the maxillary side increase in size gradually. 
The paragnaths cover most of the oral ring of 
areas VII and VIII and are only slightly sepa¬ 
rated by a narrow space from those of paired.
