Problem with cepaea shell

[vallery]

I have posted some pics and information on "Join Cepaea thread' in the 'Pictures Post' on page 9 and need some help with one of my cepaea.

I hope someone will check it out and help out. I only have two yellow morph unbanded England cepaea left and I don't want to loose him.

I hope I will be able to get some help with this before it is too late.
Thank You
