✦ Synopsis

Intraspecific variation in the appendicular skeleton of two geographically isolated populations of Triturus carnifex, one from northern Italy (Rosate, Milano) and one from central Italy (Bagnaia, Perugia), has been studied. A total of 1,746 forelimbs and 830 hindlimbs were examined. Forelimb skeletal variability was much greater in the Rosate than the Bagnaia population. Skeletal variants were present in 36.3% and 13.5% of the forelimbs, respectively, o r in 54.7% and 22.7% of the netws (P < 0.0001). There were no o 1996 WILEY-LISS, INC.
