]Marktanner-Turneretscher in 1895, believing that Gonothyrcea 

 hyalina Clark was not the same as G. liyalina Hincks, renamed it 

 after Clark. Torrey in 1902, on examining specimens of appar- 

 ently the same species, without having seen ]\Iarktanner's paper, 

 came to similar conclusions, and also renamed it after Clark, con- 

 sidering he was giving it a new name.
