 cinus, Lightfoot. — Amplexus paludosus,

 Mont. — Amplexus crenellus, Brown. 

 Though the Helix costata of Muller has for some 

 time been considered a variety of Helix pulchella, M. 

 Kickx proposes once more to separate them specifically 

 on the ground of a (supposed) difference between the 

 animals of the two forms. H e says of Helix pulchella, 

 " Incola lacteus, pallio luteolo, tentaculis inferioribus 

 brevissimis ;" and of H. costata, " Incola rufus, pallio 

 violaceo, tentaculis inferioribus vix (etiam sub lente) 

 conspicuis ;" and supposes that Muller had similar 

 reasons for separating the two as species. I have not, 

 however, found these differences to exist either in the 

 British specimens which I have examined, or in such 

 as I had collected in France ; the animals of both 

 forms agreeing with the description given by M. 

 Kickx, of that of H. pulchella. 



Not unfrequent under stones in damp places.
