[Note Guidelines] Photographer's Note
On my Valais excursions:

this tiny snail goes unnoticed in times of dry wheather. But when I visited Bratsch (Valais) in pouring rain some snails climbed the naked rocks. I present the 10 mm high Four-teeth Enid (Mollusca; Gasteropoda; Stylommatophora; Enidae; Jaminia (= Chondrula) quadridens (O.F. Müller 1774); Vierzähnige Vielfrasschnecke). The species occurs in dry and warm meadows and steppes and has a eumediterranean distribution, reaching 2'000 m a.s.l. in the Alps, extending to the Rhine valley in Germany .

ID: looking at the mouth opening you notice four teeth that supposedly give the species away. Other, similar species have zero to three teeth.

The systematics of land molluscs is well established despite the limited attractivity of the animals to man. Students of nature started assembling shell collections already during the century of Enlightenment. Today the British Museum of Natural History harbors many of the collections from all over the world. As an anecdote, the "Muséum de Genève" holds the shell collection of Jean-Baptiste de Lamarck (1744-1829), the author of "l'Histoire naturelle des animaux sans vertèbres (1815-1822)". The well known 20th century swiss psychologist Jean Piaget derived his insights into the children's development of knowledge to some extent from his zoological studies on molluscs at the University and Museum of Neuchâtel. Little wonder then that today the "Centre suisse de cartographie de la faune" in Neuchâtel (www.cscf.ch) furnishes a lot of information on Swiss molluscs :-)

Hi Dietrich.
First of all many thanks for nice words to my previous shot. I am very pleased. I have described my technique in note to last my picture.

You have pictured this small snail precisely as always. I like how well you have reproduced wet weather, texture of the snail and BG. Flash work is great as usual. We have white species of the small snails only. I do not know its correct ID. Pictured by you species have not been meeting by me. TFS and my warm wishes.
Alexei.

Hi Dietrich!
Loved the kind of lighting on the shell and the snail and as usual the composition is good!
