sists of cindery or coarse sand particles cemented 
together. 
Originally described from Washington, this 
species has since been reported from British 
Columbia (Berkeley, 1929). The present records 
are from Cold and Lazy Bays, in depths to 
30 fm. 
Nicomache lumbricalis (Fabricius) 
Sabella lumbricalis Fabricius, 1780: 374. 
Nicomache carinata Moore, 1906^: 242-244, 
pi. 11, fig. 36-39. 
Nicomache lumbricalis Berkeley, 1942: 199. 
Collections. Stations 62-40 (1); ? 35-40 
(posterior end). 
A single anterior end and a posterior frag¬ 
ment were taken. The anterior end lacks spots 
but is colored uniformly reddish brown. The 
first three setigerous segments have one (or 
two) large yellow spines in neuropodia. There 
are no transitional rostrate hooks; the fourth 
setigerous segment has series of 10 to 12 much 
smaller rostrate hooks, continued posteriorly. 
There are two preanal achaetous segments. 
Berkeley (1942: 199) has referred N. cari¬ 
nata Moore to this species—a conclusion which 
seems justified. The present records are within 
the known range, including southern Alaska 
south to Vancouver Island, Canada. 
Genus Petaloproctus Quatrefages 
Petaloproctus tenuis borealis Arwidsson 
Petaloproctus tenuis borealis Arwidsson, 1907: 
118-122, pi. 3, fig. 85-90, pi. 8, fig. 268-272; 
Berkeley, 1942: 199. 
Collection. Station 70-40 (1). 
A single tiny individual, only 11 mm. long 
and very slender, is probably a juvenile; it is 
partly surrounded by a sandy tube. The anal 
plaque is large and entire; the margin is not 
crenulate. There are 21 setigerous segments and 
two preanal, achaetous ones. The first three 
neuropodia are provided with heavy, acicular 
spines. 
Originally described from Scandinavia, this 
species has been reported from British Colum¬ 
bia by Berkeley (1942); the present individual 
is from Cold Bay, in 15 to 35 fm. 
Genus Asychis Kinberg 
? Asychis lacera (Moore) 
new combination 
Maldane lacera Moore, 1923: 235-237. 
Collection. Station 139-40 (1-, anal plaque 
missing). 
A single incomplete individual is question¬ 
ably referred to this species. The first setigerous 
segment has a conspicuous collar, deepest on 
the ventral side. The cephalic plaque is crenu¬ 
late along its margin and has about 12 lobes on 
the dorsal margin. The first setigerous segment 
lacks neuropodia but the second one has a 
transverse series of rostrate hooks, as do those 
farther back. 
This species remains unknown except through 
the original account, based on a single complete 
individual, 55 mm. long, dredged from southern 
California in 549 to 585 fm. Through the 
courtesy of the administration of the U. S. Na¬ 
tional Museum, I have been able to examine the 
type. The prostomial keel is only weakly ob¬ 
servable, hence it is here referred to Asychis 
Kinberg. Both cephalic and anal plaques are 
crenulate' at their outer margins. The cephalic 
plaque has deep lateral incisions and 12 nearly 
equitriangular lobes around its dorsal margin. 
The lateral portions are set off from the entire 
ventral lobe, and the shorter lateral lobes have 
three to five irregular, crenulate lobes. The anal 
plaque has deep, circular incisions; its ventral 
margin has four pointed, triangular lobes; the 
dorsal edge has seven shallow, triangular lobes. 
There is a conspicuous, sheathing, complete 
collar at the anterior margin of the first setig¬ 
erous segment, highest on the ventral side; it 
has a lateral incision just above the first setal 
fascicle. 
The single fragment in the collection is re¬ 
ferred to this species largely because of the deep,
