Hi all,
I am looking for type material of fossil terrestrial gastropods described by August Reuss. Specifically I want to find the syntypes of Vertigo callosa Reuss, 1849 from the Early Miocene of Tuchorice (CZ). Reuss worked, amongst others, in Prague and Vienna, and parts of his collections (microfossils) were purchased in 1891 by the Natural History Museum in Vienna. However, the mollusks aren't there, and I couldn't find any information on their whereabouts, apart from a few author's statements that the collection "might be lost". It remains uncertain though if anyone actually made a serious effort to locate it.
Any hint or suggestions would be most welcome!
Best wishes,
Thomas
