Middle Neolithic settlements include La Motte, La Butte-aux-Pierres and Lannic. They mainly concentrate on the Coast. The pottery shows Chasséen influences. Bowls are still round-bottomed, but with s-shaped profiles and vertically perforated lugs. Some geometric decoration occurs, but is rather rare. Vase-supports of Chassey-type are found as well, the Breton variety has been named the Er Lannic type and is characterised by triangular perforations, while the examples found in the Channel Islands show circular perforations. Other local pottery types include Castellic grooved ware, Souc'h-ware, and Colpo-type ware.
