Résumé

The sera of Marmota, Citellus, Sciurus, Spermophilopsis and Eutamias were investigated by means of immunotaxinomic methods to establish their antigenic relationships. The preferential similarity of Marmota and Citellus, as compared with the other genera, was established thus confirming the correctness of their association by some authors into one tribe Marmotini and of the isolation of Tamias into the tribe Tamiini. The data of turbidimetry suggest a certain isolation of Spermophilopsis from the all other Sciuridae under study that is confirmed however insufficiently by the results of immunodiffusion.
