摘　　要：研究了中国林蛙Rana chensinensis的骨骼系统,对各部分的形态结构进行了详细的描述。鼻骨与已报道的粗皮蛙和泽蛙有所不同;鼻腔骨的形状与粗皮蛙差异极大,而与泽蛙较为接近;第8椎体双凹型,属典型的参差型脊柱;肩胸骨的基部无分叉,也无缺刻,与泽蛙和粗皮蛙不相同,上胸骨较粗皮蛙大,形状与泽蛙有差异。肩带为固胸型。The skeletal system of Rana chensinensis was studied, and the modality and structure were described in detail. The os nasale is different from R. rugosa and R. limnocharis which have been reported. The os nasocavorum is very different from R. rugosa but similar with Rana limnocharis. The centrum of the eighth vertebrae is amphicoelous, so the vertebral column is diplasiocoelous typically. The base of omosternum is not divided into two branches and there is no gap, it is different from R. limnocharis and R. rugosa. The episternum of R. chensinensis is bigger than R. rugosa and is different from R. limnocharis. Pectoral girdle is firmisternia.
