" H. lucida, M.P. ; pellucida, Pen., 134; Gualt. t. 2, G. Testa 

 pellucida, umbilicata, depressa, lasvissima. 



" Pelluoid snail shell, about f of an inch long, exactly resembling 

 the foregoing " (H. ericetorum, Miill.) " in figure, but quite smooth 

 and glossy, and wholly without striae, marks, or bands. 



" Found on plants in the Eiver Stour." 



(Gualtieri's figure, quoted above, appears to represent a roughly 

 striate shell, somewhat high in the spire, with a distinctly expanded 

 peristome, and his letterpress runs, " Cochlea terrestris umbilicata, 

 minor, pellucida, flavescens.") 



Draparnaud's description of his Helix lucida (1801) is as 

 follows : 



" H. lucide. H. lucida. Coq. transparente, luisaiite, corn6 clair en 

 dessus, blanchatre en dessous ; ouverture grande. 



" Haut. 5-6 mill. ; larg. 13-16 ; diam. 11-14. 



"Helix cellaria, Miill., Verm. Hist. 230. Gualt. t. 2. f. G. 



" H. commune dans les jardins, sous les haies. (5 tours). Animal 

 pale, blanchatre, un peu grisatre en dessus. Tentacules grisatres. 

 Yeux noirs." 



Mliller's original description of cellaria is : 



" H. testa umbilicata, depressa, lutescente, nitida, subtus lactea. 

 Apertura larga." 



Pulteney's H. lucida is probably synonymous with cellaria, Miill. ; 

 but it is evident that, in using the same name and quoting the same 

 figure as Pulteney, Draparnaud intended to allude to Pulteney's 

 species ; while his reference to Miiller, whose description of cellaria 

 he practically translates, shows that in his opinion lucida and 

 cellaria were identical. The fact that in 1805 he rechristened his 

 own H. lucida, nitida, and gave the name lucida to H. nitida, Miill., 

 does not tend to simplify the matter. 



It appears from the foregoing that if the name lucida be allowed 

 to stand at all, it should bear Pulteney's name as author ; but under 

 the circumstances it seems preferable to consider lucida, Pult., a 

 synonym of cellaria, and to follow the majority of Continental 

 authorities in adopting a modification of Beck's name, draparnaldi, 

 for the present much-debated species. 



Among its other synonyms are nitens, von Alten, 1812 ; 

 obscurata, Porro in Villa, 1841 ; blauneri, Shuttl., 1843 ; fulgida, 

 Parreyss, 1851; planulata, Stabile, 1864; septentrionalis, farine- 

 sianus, and navarricus, Bgt., 1870 ; calabricus, Paulucci, 1879 ; 

 c/yrocurta, Bgt. in Servain, 1880 ; porroi, Paulucci, 1882 ; sub- 

 farinesiana, Bgt. ; barbozana, Castro ; and intermissa, Locard, 1894.
