George P. Merrill edited and compiled the list of State entries for natural history surveys and/or geological surveys for the individual States. Geological surveys may include references are non-uniform and sporadic by State. The omission of a State or Territory indicates that no public survey of the locality was undertaken during the period covered by this history. The subject matter is arranged alphabetically by States.
