Nereis pelagica — Continued. 
Survey. Dredged in 2 to 19 fathoms, on bot-

Nereis arenaceodentata Moore. 
Moore, 1903, p. 720 (sp. nov.). 
Woods Hole and vicinity, during summers of 
1902, 1903, and 1904; immature specimens 
were occasionally found among mussels and 
ascidians, mature ones common at surface on 
August evenings. — Moore. Eastern end of 
Vineyard Sound, at two stations; Bay side of 
Pasque Island; 5 to 7 fathoms, sandy bottom. — 
Survey. 
Fish Hawk station 7750 (4)*; Phalarope sta- 
tions: 3 (1)*, 83 (1)*. 
Nereis virens Sars. 
Verrill and Smith, 1873, p. 590, 317, etc.; E. B. 
Wilson, 1892; Bumpus, 1898; G. M. Gray, in 
“Biological Notes.” 
Vineyard Sound. — Verrill. Recorded from 
shores at many points in the Sound and Bay; 
likewise dredged in 5 to 10 fathoms at Fish 
Hawk station 7556 (9 large specimens), and 
Phalarope stations 26 and 79. Mainly a lit- 
toral species, dwelling in muddy sand, though 
taken occasionally at greater depths; during 
the reproductive season it leaves the burrow 
and swims freely at the surface. 
G. M. Gray records that this species may be taken 
throughout the winter locally; that it appears 
in great numbers at the surface during its re- 
productive period in March, emerging from the 
mud or sand as the tide rises, and then disap- 
pearing again. Bumpus (1898) notes that on 
March 28, 1897, these worms appeared in such 
numbers at one point in Narragansett Bay that 
the water was “actually colored by extruded 
eggs and spermatozoa.” 
This worm is doubtless an important item of 
food with many fishes, and it is used exten- 
sively as bait by line fishermen.
