During a prehistoric reconnaissance of the basin of Kasserine (Tunisia) four "escargotières" were localised. On these sites surface material was collected. It seems that on typological grounds the flint artifacts of Chabet el Bakrer-surface, Chabet Salah el Arbi and Hamlet Boulaaba Humaïme fit neither with the Typical Capsian nor with the Capsion type Bortal Fakher (Tixier 1968). They are attributed to a Capsian type Kasserine, characterised by a high index of the notches and denticulates. The industry of Chabet el Bakrer-supérieur belongs to the Upper Capsian middle phase (Camps 1968) and that of Koudiat es Souaan to the Upper Capsian recent phase.
