[摘要]
根据最近在大英博物馆发现的燕海扇 (Aviculopecten)模式种的新材料 (Fang and Morris,1999) ,燕海扇的不等壳性终于得到确认。因此 ,有必要对Newell和Boyd (1995 )的燕海扇超科 (Aviculopectinacea)的分类方案作若干修正 :1995年定义的燕海扇科 (Aviculopectinidae)无效 ,应由本文新提出的早坂海扇科 (Hayasakapectinidae)取而代之 ;埃赛海扇科 (Etheripectinidae)一名由Newell(196 9)定义的燕海扇科取代。

[Abstract]
Evidence provided by Fang and Morris （1999） requires several changes in the Newell and Boyd （1995） taxonomy of aviculopectinacean bivalves．Availability of Aviculopecten as type genus for a family of inequivalve scallops makes our1995introduction of thename Etheripectinidae unnecessary．Our1995restricted diagnosis of Aviculopectinidae is invalid but is appropriate for Hayasakapectinidae aname we introduce here．
