摘　　要：研究我国产泽蛙(Ranalimnocharis)的骨骼系统,包括对各部分形态和结构的详细描述。蝶筛骨结构特别,与已报道的粗皮蛙(R.rugosa)很不相同;第8椎体双凹型,属参差型椎体;左上喙骨在中央区部分重叠在右上喙骨之外边缘上,显示为不完全的固胸型,肩胸骨基部分叉;两性成体的掌、指以及、趾各关节下瘤的皮下均有一游离的小骨块,但1龄幼体在该位处则缺如,目前尚未见到有关此小骨块的资料。Research the skeletal system of Rana limnocharis in China, including the detailed description of modality and structure. The structure of os sphenethmoidale is very special, and is greatly different from R. rugosa that has been reported not long ago. The centrum of the eighth vertebrae is amphicoelous, so the vertebral column is diplasiocoelou typically. The left os epicoracoideum overlaps on the edge of the right os epicoracoideum at the center, which shows the incomplete arcifery. The base of omostemum is divided into two branches. These is an unattached small bone under the subarticular tubercles of palms and pes in the adult, which is absent in the larvae of one year old. Nowadays, no relevant records of the small bone are reported.
