摘　　要：快步麻晰（Eremiasvelox）隶属晰蜴科麻晰属，在我国分布于内蒙、宁夏、甘肃和新疆，在国外多分布于前苏联、土耳其等地。本文以骨髓和精集为材料，观察分析了快步麻晰的枝型，结果表明，快步麻顺利的染色体数2n＝38，NF＝38，核型公式为：2n＝36I＋2m，精母细胞减数分裂中期I中二价体为19条，与体细胞有丝分裂情况相符，雌雄个体均无明显异型性染色体，与同属的虫纹麻晰比较，快步麻晰属于比较原始的种类。Living in northwest China, Eremias velox is a kind of Lacertidae in theEremias famiIy. In this study, the author observed and analysed the Karyotype of Eremiasvelox with marrow and 3permary as examined material and found that the number of chromosome is 2n = 38, NF = 38, the Karytype is 2n = 36I + 2m, I = 19 in the meiosis of spermatophore which conforms to the rnitosis of the body cell, and neither the male nor the female has abnormal chromosome.Compared with E. vemiculata in the same family, Eremias velox is a more primitive kindof Lizard. This observation makes it possible to study the evolution of chromosome and therelation of the growth of chromosome system.
