I have given this list of references, only omitting those 

 which relate solely to the record of a locality, to show how 

 this unfortunate species has been thrown from genus to 

 genus. Let us hope that it will now find a resting-place in 

 a genus of which it is made, and, I think, rightly made, the 

 type. Li the latest paper in the list above given Mr. Waters 

 discards Stirapson''s specific name solida, and uses the later 

 palmata. He does this upon the ground that it is not clear 

 that Stimpson's description refers to this species,, and then he 

 proceeds not only to give a reference to Stimpson without 

 any mark of interrogation, but also inserts Stimpson's 

 locality as one of the habitats of tlie species. That the 

 European Arctic species belongs to the same genus, and is 

 apparently only a slight variation of the species described by 

 Stimpson, is, I think, quite clear from the fact that the 

 description and figure in the ' Invertebrata of Grand Manan/
