Cephalisation in Viverridae, Hyaenidae, Procyonidae and Ursidae Studied were the intraspecific and interspecific relationships between brain weight and body weight within Viverridae, Hyaenidae, Procyonidae and Ursidae. Inclination values of the allometrie lines are nearly the same as in Felidae and Canidae: intraspecific a˜ 0.25, interspecific a˜0.57. Comparisons for the degrees of cephalisation were done on the basis of a = 0.566, b = 0.1919 = 100 (Mustela prrtorius, Mustela vison). Viverridae and Hyaenidae have lower cephali-sations than Procyonidae and Ursidae. Hihest cephalisation within all Fissipedia was found in Procyon cancrivorus (302) and Helarctos malayanus (391), lowest in Mephitis mephitis (65).
