TAYLOR : VARIATION OF LIMNyEA PEREGRA. 299 



larger size from typical boissii, and it is possible that variety 

 globiilosa Locard would be correctly placed here also. Prof, 

 von Martens considered a specimen similar to the one outlined 

 above to be the variety carta of Kobelt. 



The specimen figured was found in a rapid stream near 

 Southport by Mr. W. H. Heathcote, who kindly gave it to me. 



The original figures are given by Dupuy in Hist. Moll. 

 France, pi. xxv., fig. 9. 



Var. bakowskyana Clessin. vShell somewhat solid, whorls convex, aper-

 island, Fife, by Mr. W. Evans. 



The original figure is contained in Mai. Bl., 1879, pi. i., f. 8. 



Var. pulchella Rofiiaen. "Shell of a small size, pale semi-transparent 

 horn colour, lines of growth rather pronounced, 

 aperture slightly margined, length 11 mill." Ann.

This pretty variety, which was originally dis- 

 covered by M. Culbeau, in a ditch, on the plain 

 of Altorf, near Seedorf, in Switzerland, has been found in a 

 ditch, near Faversham, by Miss E. B. Faiibrass, who kindly 

 gave me the specimens here figured. 



Var. gibilmannica Calcara. Shell smaller and much more solid than 

 type, spire somewhat produced, last whorl 

 flattened at sides, giving a somewhat conical 

 appearance to the shell ; aperture pyriform, 

 outer lip somewhat concave. 



This peculiar variety which is especially 

 characterized by its concave outer margin, is a Sicilian form. 

 The only figure I am aware of is that given by Sowerby in
