Lip colour is not 100%

Lip colour is not 100% reliable, though!

Lip colour problem

Thanks for yr agreement & comment Steve (of which I was unaware) ;that some white-lippeds can be brown ,& some brown-lipped (ie C.nemoralis) white , & though exception's rare Wikipedia's C.nemoralis says in areas where lipcolour is variable dissection's needed . Luckily conchsoc on brownlipped gives the areas http://www.conchsoc.org/MolluscWorld18/13 "in a few European areas white or palelipped individuals are also present in some populations i.e. Cantabria in Spain; the Pyrenees; Denmark; Yorkshire and Cornwall in England; North Wales; Western Scotland; and the west coast of Ireland" (not S.Wales, phew!)

Lip polymorphism

Thanks ChrisMcA for the link, very interesting. Good to know I am not talking complete rubbish! I have only once (knowingly) seen a Brown-lipped Snail C.nemoralis with a white lip , but it was quite a large specimen so I was suspicious (White-lipped Snail is typically smaller than Brown-lipped) so I dissected out the love dart to check.
