obscure publications

[JOSEPH E. LAFERRIERE]

I know of numerous examples of 18th- and 19th-Century names
contained in publications so obscure that there are now
only 2 or 3 extant copies. Does anyone know of an
example of a validly published sceintific name for which
it is reasonably certain no extant copies exist anywhere on the
planet? This is very relevant to recent discussions
concerning electronic publication.
