Annelids of Alaska—HARTMAN 
11 
Except for the pelagic families of polychaetes, 
the only ones not known to be represented are 
the following: Pareulepidae, Palmyridae, Am- 
phinomidae, Typhloscolecidae, Pilargiidae, Ly- 
saretidae, Apistobranchidae, Magelonidae, Diso- 
midae, and Ctenodrilidae. With the exception 
of the Amphinomidae, these are small families 
which rarely occur in collections. The amphi- 
nomids are largely tropical. 
DISCUSSION 
Family APHRODITIDAE 
Genus Aphrodita Linnaeus 
Aphrodita japonica Marenzeller 
Aphrodita Japonica Marenzeller, 1879: 111— 
112, pi. 1, fig. 2; Moore 1908: 338-339; 
Hartman, 1939: 21-22, pi. 1, fig. 1-5; Berke¬ 
ley, 1924: 187. 
Collections. Stations 116-40 (1); 131-40 
(1); 135-40 (2); 138-40 (1); 139-40 (1); 
140-40 (3). 
Some are very large, measuring 4.5 inches 
long and 2.25 inches wide. The lateral hairs are 
long but only slightly opalescent. This species 
is known to range throughout the northern 
Pacific and southward; present records are from 
Alaska in 28 to 48 fm. 
Family POLYNOIDAE 
Genus Arctonoe Chamberlin 
Arctonoe fragilis (Baird) 
Lepidonotus fragilis Baird, 1863: 108. 
Polynoe fragilis Johnson, 1897: 179-181, pi. 7, 
fig. 36, 45, pi. 8, fig. 52. 
Arctonoe fragilis Hartman, 1938c: 116; Berke¬ 
ley, 1942: 188. 
Collections. Stations 24-40 (2); 25-40 (1); 
34-40 (1). 
This species is widely known through the 
northeast Pacific; it is free-living or associated 
with echinoderms. The present records are from 
Canoe and Pavlof bays, in 25 to 150 fm. 
Arctonoe vittata (Grube) 
Fig. 2 a-f. 
Polynoe vittata Grube, 1855: 82-83. 
Polynoe lordi Johnson, 1897: 175-177, pi. 7, 
fig. 35, 44, pi. 8, fig. 51. 
Halosydnoides vittata Okuda, 1936: 565-568, 
fig. 4, 5. 
Arctonoe vittata Hartman, 1939: 29-30, pi. 3, 
fig. 33-37; Berkeley, 1942: 188. 
Collections. Stations 20-40 (2); 21-40 (1); 
20-40 to 22-40 (2); 34-40 (1); 35-40 (1); 
59-40 (1); 70-40 (1); 71-40 (2); 80-40 
(1); 83^0 (1); 129-40 (1); 131-40 or 132- 
40 (1); BT 70-41 (1); C 44-41 (2); C 71- 
41 (1); L 4-41 (4). 
These collections include individuals with at 
least three color patterns. One group is pale 
with a broad dark band across the dorsum an¬ 
teriorly; the individuals come from stations 
20-40 to 22-40, 59-40, 80-40, 83-40, 129-40 
and C 71-41. Another group has elytra more 
or less intensely mottled, as shown by Okuda 
(1936: 566); these individuals come from sta¬ 
tions 21-40, 34-40, 35-40, 71-40 and BT 70- 
41. A third group has elytra with a narrow dark 
edge on the inner and posterior margins; the 
individuals are from station L 4-41. In addition, 
there are some individuals that are entirely pale 
(preserved), coming from stations 70-40, 71- 
40, 131-40 or 132-40 and C 44-41. For each 
of these groups the characteristic setae from the 
notopodium and neuropodium of the second 
segment (first setigerous segment) have been 
examined and found to agree in details as shown 
in figures of notosetae (Fig. 2 a, 2 c) and neuro- 
setae (Fig. 2 h, 2 d) from stations 71-40 and 
80-40, and two notosetae (Fig. 2 e, 2 f) from 
station L 4-41. 
A. vittata is frequently associated with mol- 
lusks, echinoderms or other chaetopods, or it
