Annelids of Alaska—HARTMAN 
25 
before the fifth or sixth segments and the first 
few pairs are small; the last four or more seg¬ 
ments are abranchiate, but the last 10 or more 
pairs of branchiae are small and papillar. The 
proboscis has 22 rows of papillae at its distal 
end; the proximal surface (on the everted pro¬ 
boscis) is covered with low, wartlike elevations. 
N. caeca is a cold-water species, common in 
the northeast Pacific, rarely occurring south 
to central California (Hartman, 1938: 148). 
The present collections are from southwestern 
Alaska, shore to 40 fm. 
Family NEREIDAE 
Genus Neanthes Kinberg 
Neanthes brandti (Malmgren) 
Alitta brandti Malmgren, 1866: 183. 
Nereis virens Johnson, 1901: 398, pi. 3, fig. 
26-30; Moore, 1908: 344. 
Neanthes brandti Hartman, 1944£: 252. 
Collection. Lazy Bay, off Alitak Bay (5). 
This species is distinguished from N. virens 
(Sars) chiefly in the greater dentition of the 
proboscidial armature. It occurs commonly 
throughout the northeast Pacific, south to south¬ 
ern California. The present record is within 
the known range. 
Genus Cheilonereis Benham 
Cheilonereis cyclurus (Harrington) 
Nereis cyclurus Harrington, 1897: 210-220, 
pi. 16, fig. 1-3, pi. 17, fig. 1-7, pi. 18, fig. 
1-5; Johnson, 1901: 400, pi. 4, fig. 46, pi. 5, 
fig. 48-52; Moore, 1908: 343-344; Berkeley, 
1924: 292. 
Cheilonereis cyclurus Hartman, 1940: 219. 
Collection. Station 107-40 (1). 
The single individual comes from Alitak Bay, 
in 30 fm. It has previously been reported from 
Alaska (see synonymy above). 
Genus Nereis Linnaeus 
Nereis procera Ehlers 
Nereis procera Ehlers, 1868: 557-559, pi. 23, 
fig. 2; Johnson, 1901: 400-401, pi. 4, fig. 
47, pi. 5, fig. 53-59; Moore, 1908: 343; 
Berkeley, 1924: 291-292; Berkeley, 1945: 
326. 
Collection. Station 24-40 (2). 
This species has been recorded from various 
parts of the northeast Pacific. The present col¬ 
lection comes from Canoe Bay, trawled from 
125 fm. 
Nereis zonata Malmgren 
Nereis zonata Malmgren, 1867: 164, pi. 6, fig. 
34; Fauvel, 1923: 338-339,“ fig. 130. 
Collection. Station 51-40 (3). 
Length of a complete individual is 70 mm. 
for 73 setigerous segments. In one specimen 
the body cavity contains large ova. The peris- 
tomial tentacles are short, the longest reach back 
to the anterior end of the first setigerous seg¬ 
ment; the shortest are about as long as the 
prostomial antennae. Parapodial ligules do not 
change greatly from anterior to posterior re¬ 
gions, but the dorsal portion changes gradually. 
In postmedian and far posterior segments the 
differences are most notable; here the dorsal 
ligule is approximately quadrangular, the inser¬ 
tion of dorsal cirrus carried outward. Still far¬ 
ther back, the length of dorsal and ventral cirri 
comes to be increasingly great. Anal cirri are 
tapering and about as long as the last seven 
setigerous segments. 
Homogomph falcigerous notosetae are first 
present from about the thirty-second segment; 
they have a long appendage with denticulations 
on one side. The proboscis is provided with a 
pair of thick, dark-brown jaws with five blunt 
teeth on the cutting edge. On the maxillary 
ring, area I has two small cones in tandem; area 
II has about 24 larger and smaller cones in 
irregular crescentic arrangement; area III has 
about 20 larger and smaller cones in an oval
