Dear fellow collectors,
I am looking to acquire Helminthoglyptidae (Helminthoglyptas,
Monadenias) from Northern Californian localities to round out my study
collection. Specimens need not be identified (but identification is
preferable) and can be either living animals or just shells. Mature
specimens with periostracum are preferred. Detailed collecting and
locality data is important.
I can offer fossils, land snails or recent marine shells in exchange.
Let me know what you are interested in and I will send you lists.
Thanks,
--
