Nereis pelagica Continued. 



Survey. Dredged in 2 to 19 fathoms, on bot- 

 toms of sand, gravel, stones, and shells, rarely 

 in mud; sometimes present in great numbers 

 in the interstices of Amaroucium pellucidum. 

 Recorded from piles and shores at a great num- 

 ber of points throughout the region.

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 (i)*, 83 (i)*. 



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.
