Plymouth. Two specimens were dredged on rocky ground 

 immediately south of the Breakwater in May, one from Duke Rock 

 in June and one was found amongst roots of Laminaria from Rum 

 Bay in June. 



The male (Polyhostricus) and female (Sacconereis) forms of this 

 species were obtained in townets near the Eddystone in February. 

 From one Sacconereis kept in the Laboratory the young hatched 

 two weeks after the specimen was procured. 



Torquay. Five or six specimens were obtained on the shore 

 {Elwes, Journ. M.B.A., vol. 8, 1908, p. 202). 



AuTOLYTUS RUBROPUNCTATUS (Grube) : Marion and Bohretzky, Aim. 

 Golfe Marseille, 1875, p. 44 as Autolytus (Procercea) ornatus. Southern, 

 Proceed. R. Irish Acad. XXXI. 47, 1914, p. 40. 



Plymouth. Frequent in dredgings from the Sound, Asia Shoal, 

 Queen's Ground and Duke Rock. Frequent also on all the dredging 

 and trawhng grounds between Plymouth and the Eddystone and 

 westwards to Looe. 



Breeding : No specimens wdth stolons were found amongst a 

 large number examined between January and June. At the be- 

 ginning of July, one specimen was seen with a stolon just beginning 

 to form. The observations were interrupted after that month. 



Southern has pointed out that the description given by Mcintosh 

 (Mon. Brit. Ann. II. 1, p. 186) does not agree with that of other 

 observers. The Plymouth specimens have no ventral cirrus and 

 the setse have the typical bifid end-pieces of the genus Autolytus. 

 Mcintosh's coloured figure is stated to be from a Plymouth example. 



Autolytus pictus (Ehlers) : Mcintosh, Mon. Brit. Ann. II. 1, 1908, 

 p. 211. 



Plymouth. Frequently met with in dredgings from all grounds 

 in Plymouth Sound ; especially common amongst Alcyonidium and 

 sponges from Asia Shoal. Occasional specimens on all grounds 

 between Plymouth and the Eddystone, especially on rough ground. 



Breeding : Three specimens with the Polyhostricus head just com- 

 mencing to form were found in dredgings from Asia Shoal in April. 



Torquay. Rather common on the shore {Elwes, Joum. M.B.A., vol. 8, 



1908, p. 201).
