Eurymedusa Kinberg is the same as Trypanosylhs Claparede. 



Brania Quatrefages has as synonyms Grubea Quatrefages, Salvatoria 

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

 Grubea, which is preoccupied. 



AnaplosylUs Claparede is in synonymy with Syllides Oersted. 



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



Pterosyllis Claparede, Nicotia Costa, Gattiola Johnston, Thylaciphorus 

 Quatrefages, are in synonymy with Amblyosyllis Grube. 



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

Polymastus Claparede falls to Eurysyllis Ehlers.

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