Abstract: A large sample Of insectivores was collected from the Suosuoquan Formation Of Chibaerwoyi, north Junggar Basin, Xinjiang Uygur Autonomous Region, China in the summer of 1995 and 1996. Of these materials, Metexallrix has been described (Bi, 1999). This is a report on two species of Amphechinus from this locality. Although all these new materials only consist Of incomplete fragments Of lower jaws with or without teeth, a large sample now available provides information of dental variability.

摘要： 记述了采自新疆准噶尔盆地北缘吃巴尔我义早中新世索索泉组的两种双猬化石: Amphechinus bohlini sp. nov.和A. cf. A. minimus。A. bohlini在大小和i2>c>p2等形态上与甘肃塔朋布鲁克晚渐新世的A. kansuensis相似，但其p2与P4之间没有齿缺，颏孔的位置在p4的后齿根之下，下颌在p4~m1的下部较为平直，与后者有明显的差异。A. bohlini的材料较多，根据其个体的变异范围，有助于澄清对A. kansuensis与A. minimus的认识。另外
