Taxonomic list

• T. expansus type listed as from "Ferry above Turner's Falls, near Greenfield" in Hitchcock 1866/67, and from Deerfield/Greenfield by Lull 1904. The coincidence of "Greenfield" in both suggests correct placement at this site and not the traditional "Ferry above Turner's Falls" site.
