rilK ANAI'OMY OV M KKA r.A'l'lJAOTUS — KRSTUVKN. 419 



there are two Prosohranclis to wliicli (liis name has been f^iveri : 

 one the llnlla Jlcus, Liiuieus,* a T;i'iiioi;Iossat(;, the otlic^r the 

 Mitrcx Jlom, Ginelin,! a KacIiiij;lossate. 1 have concluded that 

 he referred to the Linnean species, l)ecause Ginelin's is hotter 

 known under anotlier name, but th(; doubt still remains. 



In view of this confusion and doubt about the abo\e two 

 species, T think I am justified in appealing to malacological 

 anatomists to not only make certain that their material is 

 correctly named, but also to give sucli references to figures and 

 specific descriptions as will enable subsequent readers to satisfy 

 themselves of that point also. This is particulai-l}'^ necessar}^ in 

 view of the unsettled stat(> of conchological nomenclature.
