Cantons of Switzerland the canton of Schwyz. Six of the 26 cantons are traditionally, but no longer officially, called "half-cantons" (, , , ). In two instances (Basel and Appenzell) this was a consequence of a historic division, whilst in the case of Unterwalden a historic mutual association, resulting in three pairs of half-cantons. The other 20 cantons were — and in some instances still are — though only in a context where it is needed to distinguish them from any half-cantons, typically termed "full" cantons in English. The historic half-cantons, and their pairings, are still recognizable in the first article of the
Cantons of France several smaller "communes". In the latter case, administrative services, the "gendarmerie" headquarters for example, are often situated in the principal town ("chef-lieu") of the "canton", although there are exceptions, such as "cantons" and , which have in common a "chief-town" which does not belong to either "canton". For statistical (INSEE) purposes, the twenty arrondissements of Paris – the administrative subdivisions of that city – are sometimes considered "cantons", but they serve no greater electoral function. "Cantons" also form legal districts, as seats of "Tribunaux d'instance" or "Courts of First Instance" (also, ""TI""...). Historically, the "cantons" are called "justices de paix"
