Notices of Finds. — The individuals before me are all from the West Coast 

 of Ireland : — 



Elly Bay, Blacksod Bay, Station W. 115, 16/9 (10, p. 170) : seven 

 individuals. 



Elly Bay (N. Shore), Blacksod Bay, Station W. 119 (10, p. 170): five 

 individuals. 



From one of the following stations : — L. 296-L. 300 (6, p. 41) : one 

 individual. 



S.W. of second buoy of Margaretta Shoal (Galvray Bay), Station A. 124 

 (7, p. 94), 18 m. : two individuals. 



Infurmation about Earlier Finds. — Cunningham and Eamage (1, p. 679) 

 procured this species in the Firth of Forth. They write as follows about it : — 

 " Got in great numbers inhabiting fine tubes buried in the sand, with only 

 their upper ends protruding. The tubes often have a branch in the lower part 

 of their course, and extend down to a depth of six or eight inches. The upper 

 end is quite plain and open. The worms lie in their tubes with either their 

 head or their tail uppermost indiflerently, so that they can evidently turn in 

 them. The locality whence our specimens were got was the flat sands for two 

 or three hundred yards to the west of the Birnie Eocks, where the upper ends 

 of the tubes form a sort of miniature forest all over the surface. Length three 

 or four inches when fully extended, but when contracted, it is much less." 



Hornell (2, p. 155) knows the same species as Cunningham and Eamage's 

 " Axiothea catenata " from Liverpool Bay, where it occurs extremely commonly. 

 The fact that he has observed the seven longer anal cirri shows that he refers 

 to Caesicirrus ncgkcfus. When he reports the existence of four posterior 

 achaetoiis segments, he is obviously counting in the posterior callus-formed 

 ring. 



Regeneration. — Elly Bay : 1 individual : 7 anterior segments ; 1 individual : 

 2 and 1 individual: 11 posterior setigerous segments. Station A. 124: 

 2 individuals: 11 posterior setigerous segments. 



Heteroclymene robusta Arwidsson. 



From the West Coast of Ireland — more precisely Station L. 245 (6, p. 38) 

 or Fahy Bay, Channel and Bar, l'8-5'5 m. — comes a small individual which is 

 complete, and which, like the first and hitherto only known complete individual 

 (5, p. 227), possesses nineteen setigerous and five posterior achaetous segments. 

 The anterior region is regenerated as far as the first setigerous segment 

 inclusive, and the posterior region from the ninth setigerous segment inclusive. 

 The length of the second to the eighth setigerous segments, which are 

 normally developed, is 9"5 mm.
