Czekanowski classified Europe into four pure races.
 The four pure races were the Nordic, Mediterranean (Ibero-Insular), Lapponoid and Armenoid.
The Lapponoid included the central and eastern Europeans along Europe longitudely as well as the Sami people of Northern Europe.

Czekanowski classified six subraces in Europe which were mixed types of the pure races.
  The six mixed racial subraces were: the Northwestern (Nordic and Mediterranean), the Subnordic (Nordic and Lapponoid), Alpine (Nordic and Armenoid), the Littoral (Mediterranean and Armenoid), Sublapponoid (Mediterranean and Lapponoid) and the Dinaric (Lapponoid and Armenoid).
The Sublapponoid subrace (also called Pile Dwelling race) lived around the Swiss lakes.

The Greek letters which symbolise races and types could be capital or lower case.
