44 
shorter ones are very finely toothed at the tip. 
Branchiae consist of many simple filaments that 
are palmately arranged. The tube is thick-walled 
and made up of sand and mud that is closely 
packed. 
Amphitrite palmata Moore (1905c: 858), 
from Alaska, is here considered to be identical; 
since the specific name palmata was preoccupied 
by Malmgren, the specific name radiata, was 
later proposed (Moore, 1908: 350). 
The present records extend from Icy Straits, 
east end of Pleasant Island, west and north to 
the east end of Walrus Island, Bering Sea; the 
bathymetric range is shore to 38 fm. 
Genus Neoleprea Hessle 
Neoleprea spiralis (Johnson) 
Amphitrite spiralis Johnson, 1901: 426-427, 
pi. 16, fig. 169-171. 
Neoleprea spiralis Hessle, 1917: 193; Berkeley, 
1942: 205. 
Terebella spiralis Berkeley, 1929: 308-309. 
Collection. Station 12-40 (1). 
There are 40 thoracic setigerous segments. 
The two pairs of branchiae are dendritically 
branched. The anterior end lacks thoracic lap¬ 
pets. Thoracic setae are distally toothed. 
Originally recorded from Washington, this 
species has been further reported from British 
Columbia (Berkeley, 1929, 1942); the present 
record extends the range to Canoe Bay, Alaska, 
shore. 
Genus Eupolymnia Verrill 
Eupolymnia crescentis Chamberlin 
Eupolymnia crescentis Chamberlin, 1919: 265- 
266, pi. 3, fig. 6-7. 
Collection. Station 128-40 (14). 
The peristomial fold is provided with num¬ 
erous small eyespots. This species was first 
described from northern California; the present 
record is from Shelikof Strait, off Hallo Bay, 
an 35 to 48 fm.

Genus Neoamphitrite Hessle 
Neoamphitrite robusta (Johnson) 
Amphitrite rohusta Johnson, 1901: 425-426, 
pi. 16, fig. 164-168; Moore, 1908: 350. 
Neoamphitrite rohusta Hessle, 1917: 184; 
Berkeley, 1942: 202. 
Terebella rohusta Berkeley, 1929: 308. 
Collections. Stations C 5-41 (1); D 3-41 
( 1 ). 
Both records are in the vicinity of the known 
range in the northeast Pacific. The localities are 
Icy Straits in 7 fm., and Castle Bay, in 21 to 
52 fm. 
Genus NlCOLEA Malmgren 
Nicolea zostericola (Oersted) 
Terehella zostericola Oersted, 1844: 68. 
Nicolea zostericola Fauvel, 1927: 261-262, fig. 
90. 
Collection. Station D 15-41 (1). 
There are 15 thoracic setigerous segments; 
uncini are present from the second of these. 
Branchiae number two pairs and are dendrit¬ 
ically branched; they are inserted on the two 
segments preceding the first setigerous segment. 
The peristomium has a row of eyespots. Nephri- 
dial papillae are present on the second branchial 
segment and on the third and fourth setigerous 
segments; they have long lobes externally. 
Thoracic dorsal setae are smooth and capillary; 
uncini are avicular. 
In so far as I am aware, this is the first record 
from the north Pacific; it originates 20 miles 
north of St. Lawrence Island, in the Bering Sea, 
in 15 to 16 fm. 
Genus Thelepus Leuckart 
Thelepus hamatus Moore 
Thelepus hamatus Moore, 1905: 856-858, pi. 
44, fig. 16-18; Berkeley, 1929: 309.
