NO. 3667 POLYCHAETES—BANSE AND HOBSON 45 
Found at stations 1-4 and 6-8. New for the northeast Pacific. 
Previously known from the Sea of Okhotsk. 
Melinna elisabethae McIntosh 
Melinna elisabethae.— Ushakov, 1955, p. 363. 
There are four moderately well-preserved specimens. The gills 
form groups of one anterior and three posterior filaments. The thoracal 
setigers are arranged as in M. cristata (Sars) although the fourth 
bundle of the fine ventral capillary setae is visible only in transparent 
animals. The strong dorsal hooks have relatively short and broad 
bases, and the tips are bent backward by almost 180°, more so than 
pictured by Ushakov (1955, fig. 1834p). There is no canal in the tip. 
The uncini have four teeth. The species is a selective deposit feeder. 
Found at stations 1, 3, and 4. New for the northeastern Pacific. 
Previously known from the Sea of Okhotsk and the Arctic. 
Family TEREBELLIDAE 
Neoamphitrite edwardsi (Quatrefages), new combination 
Amphitrite edwardsii—Fauvel, 1923, p. 245.—Hartman, 1961, p. 497.—Imajima 
and Hartman, 1964, p. 335. 
There are three large specimens up to 13.5 cm long. Eyes appear 
to be absent. Seventeen setigers have notosetae; double rows of uncini 
occur from the eighth to the seventeenth setiger. Lateral folds are 
large on the two first segments bearing gills and are practically absent 
on the third one. Nephridial papillae are present on 9 consecutive 
segments, not on 12 as in WN. robusta (Johnson), starting on the second 
segment with gills. There are 11 or 12 ventral shields. 
We place the species into the genus Neoamphitrite because of the 
arborescent gills, but we have not studied the nephridia. Hessle 
(1917) has tentatively suggested this action. 
Found at station 2 and near station 7. New for Puget Sound. 
Previously known in the North Pacific from Japan. 
Pista fasciata (Grube) sensu Marenzeller 
FicuREs 8g, h 
Pista fasciata.—Imajima and Hartman, 1964, p. 343. 
Since there is some confusion about this species in the literature, 
the following may be observed: Our specimens, which are more than 
10 cm long, agree well with the accounts of Marenzeller (1884) and 
Imajima and Hartman (1964). The lateral folds are shaped as de- 
scribed by the latter authors. Dorsally, the fourth segment (first 
setiger) is very much higher than the preceding ones. Nephridial
