摘　　要：本文对昆嵛林蛙(Rana kunyuensis)的蝌蚪口部外形和口咽腔形态结构进行了观察,并与长肢林蛙进行了比较。结果表明它们有着基本相似的形态特征,但也存在明显的差别:昆嵛林蛙蝌蚪的上唇齿比长肢林蛙少一行;昆嵛林蛙蝌蚪口腔内突起数量明显少于长肢林蛙;昆嵛林蛙腺区不明显,而长肢林蛙腺区明显。The external and internal oral morphology of tadpoles of Rana kunyuensis was observed and compared with Rana longicrus. Their general morphological characteristics are similar between the tadpoles of two species frogs. The mian upper labial with 2 tooth row in the tadpole of Rana kunyuensis is one row less than that in Rana longicrus. The buccal number of papilla of Rana kunyuensis is much less than Rana longicrus, and the glandular zone of Rana kunyuensis is unconspicuous.
