GUDE & WOODWARD : ON HELICELLA, Fi^RUSSAC. 181

What then becomes of Ferussac's fourth group, Heliomanes, to 

 which the name Helicella has lately and wrongfully become 

 attached ? 



Out of the thirty species, eight have been removed to genera in 

 quite other families, viz. to Euparypho. — variegata, Chemn., pisana, 

 Miiller, suhdentafa, Fer., planata, Chemn. ; to Cepolis — carnicolor, 

 Fer. [= varians, Menke] ; to TrochomorpJia — exclusa, Fer., trochi- 

 formis, Fer. While the identity of elfordia, Fer., has not been 

 established . 



The remaining twenty-one (referred by Beck ^* to the subgenus 

 Theha, which, as already noted, had been established by Eisso for 

 the cartusiana group), will come under the generic name of Helicopsis, 

 proposed by Fitzinger^^ in 1833 for the Helix striata of Miiller, 

 Pilsbry,^^ among the many slips inevitable in pioneer work such as 

 his, converted the Helicopis of Fabricius, 1807,^^ into Helicopsis, 

 and hence set Fitzinger's name aside as pre-occupied, but the two 

 names are quite distinct, and differ etymologically, so that 

 Fitzinger's name must be accepted, although it unfortunately 

 excludes the better-known and widely used Xerophila of Held, 

 1837, whicb would otherwise have replaced the misapplied Helicella 

 of Pilsbry. 



Of the several subgenera into which Helicopsis has been divided, 

 only five are represented among the species enumerated by 

 Ferussac, namely : Cernuella, Schliiter (olim Heliomanes, auctt. 

 non Ferussac ) ; Xerophila, Held ; Helicopsis, s.s. ; Jacosta, Gray ; 

 and Xeroclivia, Monterosato {olim. Trochula, Schliiter, 1838, non 

 Trochulus, Humphrey, 1797). 



In view, however, of the numerous changes in the nomenclature 

 of the subgenera of Helicopsis th*t have become necessary, it may 

 be of service if the whole of them be restated here as it seems to us 

 they should stand : —
