[Notes on the reptiles of Tunisia. V. Biometric characteristics of Mauremys caspica leprosa (Schweigger, 1812) (Reptilia: Emydidae)].
This morphological study is based on 45 specimens of Mauremys caspica leprosa (Reptilia: Emydidae) sampled in northern and central Tunisia. A first principal component analysis of 9 variables: 8 measurements of the shell and the weight in life, allow to define a factor "size"; a second analysis of these variables divided by the size make obvious a factor "shape". In the plane of these two factors, our specimens may be classified into 6 groups from the hatchling stage to the large adults; in addition, the factor shape express a dysharmony in the growth, beginning with the third group (weight: 300 to 500 g). Among the 8 parameters used, 4 are adequate to characterize the morphology of this turtle.
