Good morning all,
I am trying to check or find reliable update article on validity of taxon
Helix bushi Du Bois de Montpereux(date 1837 ?). Snails coming with this
labelling usually come from Russia.
Googling does not yield much result pages except for a few pages in Russian
(musea pages) Author's name does not yield much either except for Du Bois
von Montpereux on an antiquarian book seller's list.
The point of this post is to try to find out in how far Helix bushi might
be related to lucorum. If two taxons are valid as species, what are the
criteria for ID 2 species.
Tks much in advance for any additional info.
WKR
