is more robust than that of A. Edwarsi or A. punctatus and the 

 living worms were picked out as distinct from the other species 

 found here, on account of their form and movements, before the 

 pharynx was examined. I agree with Southern that many of the 

 records of this species in the literature are unreliable.

Plymouth. Three or four specimens in dredgings from Queen's 

 Ground and Millbay Pit. 



Breeding : In January and February the stolon was just begin- 

 ning to form ; in July a large stolon was well developed. 



The specimens agreed with de St. Joseph's description. The 

 massive black tentacles and dorsal cirri of the first segment were 

 very conspicuous. The anal cirri had the same form, and the 

 pharynx has 16 equal teeth. I have found no other record of the 

 species except that by de St. Joseph, who took it at Dinard.

Plymouth. Occasional specimens have been taken on the 

 principal dredging grounds in the Sound, as well as on the trawling 

 grounds between Plymouth and the Eddystone and Eddystone and 

 Looe. The specimens all had the characteristic colour. 



Breeding : With stolons in December, January, April, May and 

 June. One specimen in August had no stolon. 



Torquay. One specimen {Ehves, Journ. M.B.A., vol. 8, 1908, p. 202). 

 Malaquin (Syllidiens, Lille, 1893, p. 76) makes a new genus, Autoly- 

 tides for this species, in which the pharynx has a plain border, 

 without teeth of any kind.

Plymouth. Frequently met with in Plymouth Sound (w.g.) ; 

 dredgings from Millbay Channel, Asia and Queen's Ground (t.v.h., 

 R.A.T., E.J. a.) ; amongst Ascidians and sponges from the piles at 

 Millbay Dock (r.a.t., e.j.a.). 



Salcombe. On the shore at the Salstone and dredged in the 

 channel to the west of the Salstone (Journ. M.B.A., vol. 6, 1900, p. 190).

Plymouth. Six specimens were obtained from amongst Ascidians 

 from a raft moored in Cawsand Bay, September 30th, 1914. 



Breeding : The specimens bore no stolons, but in one specimen 

 three of the middle segments were considerably enlarged.
