为了了解史氏蟾蜍骨骼系统的形态特点及史氏蟾蜍种组与一般蟾蜍种组的差别,本研究运用硬骨一软骨双染色技术封史氏蟾蜍的骨骼系统做了较全面地观察研究,包括头骨、脊柱和前後肢带骨;并对各块形状、位置以及与邻近骨块的关系进行了详细地描述。从整体看,头宽大于头长。各部分骨骼特征:肩带弧胸型,无肩胸骨,正胸骨为一片扁宽软骨,无分叉,也无缺刻;椎体前凹型;鼻间软骨小;犁骨小且无犁骨齿;舌器细长无前突;无鼓膜,无耳柱骨,
The osteoiogy of Bufo stejnegeri was described in detail by double-staining method, in order to understanding its characteristics and the difference between Bufo stejnegeri group and Bufo gargarizans group. Its characters were compared with Bufo gargarizans. It provided structural propertied in eco- and evo-morphological analysis for the evolution and species group of bufo in China.
