differ from the populations of France and of Spain. In the same way Barbue canalii VALENCIENNE cannot be preserved on account of the very same considerations or even regarded as subspecies, since the Italian populations are uniform. Barbue peloponneneius VALENCIENNE must be regarded synonymous as long as more thorough informations will not be gathered concerning this form, partly because this species has the same number of scales /about 55/ as Barbue petényi HECKEL, and partly because KOLLER /1927/ indicated Barbus meridionalis meridionalis RISSO from the River Aepropotamos in Greece, and STEPHANIDIS /1950/ reported Barbus meridiona lis petényi HECKEL likewise from Greece. Therefore Barbus petényi HECKEL cannot be accepted as a distinct species, but as a subspeciee only. Pseudobarbue Leonhardii BIELZ is indubitably synonymoue

, because its description and lté place of origin are identical with those of Barbus meridionalis petény

i HECKEL, and there lives only one species in the habitat mentioned above. The variety Barbue meridionalis RISSO var.

rebell KOLLER has to be regarded as invalid until further scientific research, because it had been described on the basis of a very few /4/ specimens only. Thus there remains as the basis of further research one species /

Barbus meridionalis RISS0/ and two /probable/ subspecies /

Barbus meridionalis caninus BONAPARTE and Barbus meridionalis petényi HECKEL/. But in may present paper I wish to deal only with the possible differentiation of the two subspecies mentioned above. Most of the authors report Barbus meridionalis meri dionalis RISSO and not Barbua meridionalis caninus BONAPARTE from the Balkan Peninsula. On the basis of literatura there a very small difference may be established only between the two forms.If further investigations allow any differentiation between Barbua meridionalis meridionalis RISSO and Barbus
