Abstract: This paper describes the karyotypes of three species of the Canidae and Mustelidae of mammals caught in Xinjiang. The specimens of chromosomes are prepared by the methods of peripheral blood lymphocyte culture and the conventional bone marrow culture.Tibetan Fox (Vulpes ferrilatus) is 2n = 36. Its chromosomes are divided into two groups: the first group(1st-15th pairs) is metacentric(M) and the second group(16th?8th pairs) is submetacentric(SM).In the 3rd, 4th, 5th and 6th pairs of chromosomes G-bands are so obvious that they are easily identified.For Tiger Stoat (Vormela peregusna), 2n = 38. Its chromosomes are divided into thres groups: the first groupdst-llth pairs) is M; the second group(12th-16th pairs) is SM; and the third group (17th-18th pairs) is acocentric(A). The chromosome X is M. As the chromosome Y is so small that its centriole cannot easily be identified. There is a secondary constriction on each of the long arms of 1st-3rd pairs of the chromosomes.For Musked polecat(Mustela eversmanni), 2n = 38. Its chromosomes are divided into 3 groups; the first group (1st條lth pairs) is M; the second group(11th-16th pairs) is SM. and tbe third group(17th-19th pairs) is A. There is a secondary constriction on the arm of the 18th pair of the chromosomes.The chromosome numbers, morphology and N.F, in the karyotype of Musked polecat reported above are more or less different from those reported by rpaφoдaTCKнй, 1976, (New Siberian Is.) and by Wang Zongren, 1984, (Huailai, Hebei). These differences are mainly caused by Non-Robertsonian translocation. The differences of Karyotypes of Musked polecat are related to the subspecies differentiation.
