You can start with Linnaeus.  For many invertebrate species he listed
references to several illustrations, all of which are eligible for lectotype
designation.  In some cases all of the referenced figures represent
different species (and indeed in many cases different genera).  Later
workers selected one of the referenced figures as representative of the
lectotype.  The same is true of Gmelin who not only referred to figures and
used no illustrations of his own, but who had no collection from which a
specimen might be found.
