450 ECHINODEKMS OF THE BRITISH ISLES 



which says (Art. 23) : " When a species is transferred to another 

 than the original genus or the specific name is combined with any 

 other generic name than that with which it was originally published, 

 the name of the author of tlie specific name is retained in the notation 

 but placed in parenthesis." 



Thus, e.g. it is Asterias rubens Linn, or Echimis esculentus Linn., 

 as these species still remain within the old genera Asterias or Echinus, 

 to which they were referred by Linnaeus. But it is Solaster endeca 

 (Linn.), as this species is now referred to the genus Solaster instead 

 of the genus Asterias, in which it was placed by Linnaeus ; it is 

 Ophiactis abyssicola (M. Sars), this species having originally been 

 referred to the genus Ampliiura by M. Sars, who named it Amphiura 

 abyssicola, while it is now referred to the genus Ophiactis — and so on.
