摘　　要：采用透明骨骼染色法,观测到了青海沙蜥红原亚种雌体比较完整的骨骼系统,为沙蜥属的分类及演化提供骨骼方面的资料。其特征是高颅型头骨,眼窝完整;颈椎8枚,躯椎13枚,荐椎2枚,尾椎多于21枚。我们第1次详细描述了眶间隔,鼻甲软骨,耳柱骨软骨部分等结构,并且在硬骨系统中也对以往的沙蜥骨骼系统有所补充:在前肢肱骨与尺骨间的韧带内,存在1块小骨,这块骨对应于后肢髌骨的位置,我们暂时称之为肘骨。在前肢腕骨与掌骨的腹面,有1块平面方形的骨骼,位于连接腕骨与各掌骨的韧带中间,我们暂时称之为垫骨。A detailed study of the skeletal system of female Phrynocephalus vlangalii hongyuanensis Zhao, Jiang and Huang, 1980 was conducted. It is tropibasic skull, with complete orbits. The columna vertebralis is made up of eight vertebrae cericalises, thirteen trunk vertebraes, two vertebrae sacrales and more than twenty-one vertebrae coccygeaes. We observed allcartilages is due to new technique. This paper is the first to describe the ＂ likepatella＂, which is a bone in pectoral appendage equivalent to patella, and ＂cushiony＂, which is a bone under carpal. We chose these names and described them by ourselves because there is no mention of them in any textbook or scientific article.
