NOTE ON THE NAME MARGINELLA GRACILIS 

 By J.-R. le B. Tomlin. 



M. Cossmann has recently suggested (Journ. de 

 Conchyl., LXIV, p. 157, footnote) Uiat his naine Margi- 

 nella Sacyi may replace that of M. gracilis Fuchs, if 

 thèse two species prove to be identical. IL is, therefore, 

 well to point ont that in L899 M. Cossmann himself pro- 

 posed the naine M. Fuschi (Essais Paléoconch. Gomp., 

 III, p. 91) lo replace M . gracilis Fuchs. 



Four différent species in this genus hâve been des- 

 cnbed as gracilis, viz. : 



M. gracilis C.-B. Adams, 1850. 



M. gracilis Edwards, 1854 = subgracilis Rédfield. 



M. gracilis Fuchs, 18(59 = Fucksi Cossmann. 



M. gracilis May, 1911 = Maugeana fîedley.
