The Ionian Islands are traditionally called the Heptanese, but that changed in 1911.
 Another chain with similar orientation is the Tuamotu Archipelago; its older, northerly trend is the Line Islands
 Some former island sites have retained designations as islands after the draining/subsidence of surrounding waters and their fixed linkage to land (England's Isle of Ely and Vancouver's Granville Island being respective cases in point)
