Paedophylax Claparede, Schmardia, Syllia and Gossia Quatrefages, are rej?arded 

 as synonymous with Exogone Oersted. 



Eurymedusa Kinberg is the same as TrypanosylHs Claparede. 



Brania Quatrefages has as synonyms Grubea Quatrefages, Salvatoria 

 Mcintosh, and GrubeosylUs Verrill, the latter unnecessarily proposed to replace 

 Grubea, which is preoccupied. 



Anaplosyllis Claparede is in synonymy with Syllides Oersted. 



Claparedia Quatrefages is referable, with some doubt, to Eusyllis Malmgren. 



Pterosyllis Claparede, Nicotia Costa, Gattiola Johnston, Thylaciphorus 

 Quatrefages, are in synonymy with Amblyosyllis Grube. 



Tetraglene Grube ( = epitokous form) and Pseudosyllis Grube are congeneric 

 with Trypanosyllis Claparede. 



Polymastus Claparede falls to EurysylUs Ehlers. 



Myrianida Milne Edwards (1845) is regarded as synonymous with Myriana 

 Savigny (1820) since the types M. fasciata Milne Edwards and M. longissima 

 Savigny, are one and the same species and identical with Nereis pinnigera Mon- 

 tagu (1808). Nereimyra Blainville is also a synonym of Myriana.
