POLYCII^TA OF PLYMOUTH. 615 



EuLALiA BiLiNEATA (Johiistoii) : McIntosJi, Mon. Brit. Ann. II. 1, 1908, 

 p. 51. 



Plymouth. Frequent amongst dredgings from the Sound, 

 especially from Millbay Channel and Asia Shoal. Dredged of? 

 Yealm Head. Amongst roots of Laminaria from Cawsand Bay. 



EuLALiA AUREA Gravier : Recherches sur les Phyllodociens, Bull. Sci. 

 France et Belg. XXIX. 1896, p. 309. 



Plymouth. Common on all the dredging grounds in Plymouth 

 Sound. Occasional specimens are met with on most of the grounds 

 near shore, e.g. off Yealm Head. 



Mcintosh (Mon. Brit. Ann. II. 1, 1908, p. CO) regards E. aurea 

 as a variety of E. viridis. The general shape of the animal, the 

 character of its movements, its size when mature and its usual 

 habitat seem to mark it clearly from that form. The most striking 

 difference is, however, the distinctive colour and colour pattern of 

 each of the forms, w^hich is very constant. In most respects 

 E. aurea seems nearer to E. bilineata than to E. viridis. 



Breeding : With eggs January to July (r.a.t., e.j.a.). 



Torquay. On the shore, but not above the Laminarian zone 

 {Ehves, Journ. M.B.A., vol. 8, 1909, p. 348). 



EuLALiA ORNATA de St. Joseph : Ann. Sci. Nat. Zool. V. 1888, p. 291. 



Plymouth. In dredgings from the Sound, especially Millbay 

 Channel and Asia Shoal. Much less frequent than E. aurea. 



Mcintosh (Mon. Brit. Ann. II. 1, 1908, p. 59) regards this form also 

 as a variety of E. viridis. The well-marked colour pattern, its general 

 shape and the character of its movements appear to me to justify 

 doubts as to this conclusion. 



Torquay. Fairly common, but not above the Laminarian zone 

 {Elwes, Journ. M.B.A., vol. 8, 1909, p. 347). 



Eulalia viridis (0. F. Miiller) : Mcintosh, Mon. Brit. Ann. II. 1, 1908, 

 p. 55. 



Plymouth. Common on rocky shores in the Sound and on the 

 coast. Its usual home seems to be amongst shore sea- weeds, to 

 which the large gelatinous masses of green eggs are attached. It 

 is, however, occasionally taken in dredgings from the Sound, es- 

 pecially in an immature state, and specimens have even been taken 

 on the Eddystone Grounds. 



Breeding : Eggs in January and February ; abundant in May 

 and June. None found at end of July or in August (a.j.s.). 



Salcombe. From dredgings between Salstone and Snape's Point 

 (Journ. M.B.A., vol. 6, 1900, p. 193). 



Exmouth. Two specimens were obtained from Orcombe Rocks, 

 at the mouth of the estuary (Journ. M.B.A., vol. 6, 1902, p. 320). 



Torquay. Particularly abundant where the hmestone rocks
