Synonymy of Genera. 



Eracia Grube is a synonym of Eulalea Savigny. 



Porroa Quatrefages is a synonym of Eteone Savigny, as is also Eteonella 

 Mcintosh. 



PterocLrrus Claparede is identical with Sige Grube, both having the same 

 species as the type, Pterocirrus macroceros = Sige fusigera, macroceros being the 

 older. 



Mesomystides Czerniavsky is a synonym of Mystides Theel. 



Trachelophyllmn Levinsen has been withdrawn into Notophyllum Oersted, 

 its type, T. luikeni Levinsen being the same species as the type of Notophyllum, 

 N. foliosum (M. Sars). 



Macrophyllum Schmarda is very probably a synonym of Notophyllum 

 Oersted, but as the type of the typical species (M. splendens) no longer exists, 

 and the species is known only from the original accoimt, the position of the genus 

 is somewhat doubtful. 



The same is true of Myriacyclum Grube, based upon Notophyllum myria- 

 cyclum Schmarda. Until this species is again found it will probably be impossible 

 correctly to place it. 



The types of the two species included by Quatrefages ia his genus Kin- 

 bergia are also lost and the species {Phyllodoce macropthalma Grube and P. 

 longidrris Grube) have not been identified recently. Five pairs of tentac- 

 ular cirri are ascribed to members of this genus; but Bergstrom's suggestion 

 that Grube enumerated as the first of these nuchal organs unusually strongly 

 extruded seems plausible. 



Eunomia Risso (1826), regarded by its author as near Phyllodoce, is doubtful 

 even as to family. No types of its two species {E. tympana and E. viridissima) 

 exist. The genus should probably be discarded. 



Nothis Pruvot (1885) is similarly unrecognizable. 



Protocarobia and Paracarobia were established by Czerniawsky (1882) as
