POLYCH.ETA OF PLYMOUTH, 619 



Plymouth. From the piles of the wharf at Millbay Docks. 

 Fairly numerous. Heteronereid males in February, females filled 

 with ova in March {Ramsay, I.e.). 



ToEQUAY. One male Heteronereid in February at Oddicombe 

 {Elwes, Journ. M.B.A., vol. 8, 1909, p. 351 as L. Vaillanti). 



Nereis pelagica Linnseus : Mcintosh, Mon. Brit. Ann. II. 2, 1910, 

 p. 267. 



Plymouth. Frequent amongst weeds on rocky shores and 

 from dredgings in all parts of the Sound ; also Wembury Bay and 

 Yealm River (t.v.h., e.j.a.). 



ExMOUTH. Dredged amongst masses of sponge {Halichondria 

 panicea) in the main channel (Journ. M.B.A., vol. 6, 1902, p. 318). 



Torquay. Extremely common in the roots of Laminaria. 

 Heteronereids in January and February (Elwes, Journ. M.B.A., vol. 8, 

 1909, p. 351). 



Nereis zonata Malmgren : Fauvel, Eesult. Camp. Sci. Monaco, Fas. 

 XLVI. Annel. Polych. 1914, p. 177. 



Plymouth. Common on the dredging and trawling grounds 

 off Plymouth in depths of from 20-40 fms. Recorded previously 

 as N. Jjrocera Ehlers (Journ. M.B.A., vol. 5, 1899, p. 481). 



Dredged by Crawshay S.S.W. of the Eddystone in depths of 

 42-49 fms. (Journ. M.B.A., vol. 9, 1912, p. 342 as N. pelagica). 



It seems to me probable that this is the species which Johnston 

 calls Nereis fimbriata 0. F. Miiller. He states that it inhabits the 

 " coralline region," and he obtained it not only at Berwick Bay but 

 also from Polperro (Cat. Worms. Brit. Mus. 1865, pp. 155 and 341). 



Nereis (Perinereis) cultrifera Grube : Mcintosh, Mon. Brit. Ann. 

 II. 2, 1910, p. 280. 



Plymouth, Common on the shores all around the Sound, 

 Wembury Bay, Yealm Estuary, especially in muddy gravel. Young 

 specimens frequent in dredgings.

 fine mud. Most common where soil is gravel mixed with sand and 

 mud (Journ. M.B.A., vol. 6, 1900, p. 192).

 quite at the mouth of the estuary (Journ. M.B.A., vol. 6, I902,"p. 318). 



Torquay, Under stones, not very common, on the edge of the 

 submerged forest at Tor Abbey Sands {Elwes, Journ. M.B.A., vol. 8,.

 Brit. Ann. II. 2, 1910, p. 295, 



Plymouth. Mcintosh {loc. cit.) records this species from Ply- 

 mouth, probably in material sent from the Laboratory. I have 

 not yet found it myself.
