" As Kœhler (1907) and Fisher (1911) have jwinted out, this species 

 was wrongly referred to the genus Plutonaster, and properly takes its place 

 in the Family Pcntagonasteridœ {G<y)iiasteri(lœ) rather than in the ArcJi- 

 asterklce, in which it formerly stood. I have for convenience adopted the 

 generic name used by Fisher, without entering into the academic question 

 of whether it or Adrogoninm is more j)roperly apphcable to the genus to 

 wliich it is here applied. 



" Dr. Kœhler, who has had considerable experience both of the tj-pe 

 of this species and of the variety longdbrancIdaU, has been good enough to 

 examine one of my specimens. He informs me that, although its arms are 

 more pointed than in the si)ecimens he has seen of the type, it cannot be 

 refen'ed to the variety, in which the arms are, relatively, much more slender 

 and longer. 



" This species reached a very large size in Irish waters. The two 

 largest specimens obtained by the Helga measm-ed R = 192mm., r = 70mm. 

 and R = 178 mm., r=57 mm. respectively. 



" Small s^Decimens are rather scarce, for out of nineteen of the Helga 

 specimens in which the arms were measured, in five only was R less than 

 80 mm."
