The Upper Cretaceous belemnites from the Kristianstad area (northeastern Scania, Sweden) are described and the variation of homogeneous samples is analysed using uni- and bivariate 'biometric methods. The stratigraphical occurrence of the belemnites is discussed and their geographical distribution commented upon. Fourteen species and subspecies are described which represent the following five genera: Actinocarnax Miller, Gonioteuthis Bayle, Belernnellocarnax Naidin, Belemnitella d'Orbigny, and Belemnella Nowak. These genera belong to the family Belemnitellidae Pavlov. One new subspecies is established, Gonioteuthis quadrata scaniensis, and a lectotype for Belernnellocarnax balsvikensis ( Brotzen, 1960) is d esignated. It is shown that the guard in species of the genera Belemnitella and Belemnella is prolonged ventrally along the ventral fissure in a tongue-like extension.
