This study presents Information on biometry and colouring of Galemys pyrenaicus. The material stu-died covers the entire distribution area of this species on the Iberian Peninsula. Based on the data ex-amined, no significant geographic differences were found as far as skull size was concerned. However, skull sizes and some of the body measurements taken from animals native to the Pyrenees and in-cluded in the subspecies pyrenaicus, are intennediate between subspecies from Galicia and the Iberian Mountains, and included in the subspecies rufulus. These data diminish some of the validity ac-corded to craniometric measures as one criterion to justify the existence of subspecies. Colour allows for a better differentiation although the chorological patterns do not coincide with those established by other authors. We suggest that Galemys pyrenaicus is distributed in totally or partially isolated po-pulations, which could favour the process of morphological differentiation. This emphasises the impor-tance of preserving every population area of this species.
