According to the specimens of ulna-radius of the Cape Hare (Lepus capensie) shot in fall and winter in Shanxi province, China, the ossifications of epiphyses cartilage of ulna-radius are divided into 4 stages. With weight of eye lens as a reference, it is proved that the age criterion could be used to distinguish young less than 6-7 months old from those older. This is a pragmatic method to analyze age composition of game-bag in the early period of shooting season when younger holds a larger proportion in the hare population. It also is userul in judging the age of hares trapped and estimating the effects of predation on the hare population structure.
