Résumé

On ground of a series of investigations the author concludes that the marmot genus (Marmota) primarily originated the Central Asia on hilly surroundings. Therefrom the marmot spread over several directions-to the north the sibirica form, to the north-west and the west a series of forms (baibacina, centralis, schaganensis and bobac) to whom belongs the Marmota b. menzbieri too, a previous form developped in a form apart. And lastly a branch of the primary population moved higher to along with the raise of the Tibet-upland and the Himalayas, developping into a well prononced highlands type, to which belongs also the long-tailed marmot. This last spread from the mountaineous areas of Central Asia in the Pamir-Alai system and further into Tian-Shian, thus separating the areal of the menzbieri form on the extreme west of Tian-Shian from the basical area of M. bobac.
