| 摘 要： | 对中华鼢鼠和罗氏鼢鼠阴茎骨的解剖,发现其形状呈背腹扁平、两端膨大、中央为一弯曲细柄状,略似亚铃形。罗氏鼢鼠远端部呈扁平三角形,中华鼢鼠远端腹面有一凹陷。对其长度和重量拟合以指数函数,罗氏鼢鼠为y=0.19e~(0.47x),中华鼢鼠为y=0.27e~(0.46x)。并进行了阴茎骨作为分类和年龄鉴定指标的讨论。

| Abstract: | The baculum which dorsal and ventral sides are flat consists of an expan ded proximal and distal, a tapering shaft. Regresion curve of the baculum of M. rothschildi and M. fontanieri with regard to length and weight are Y=0.19e~(0.47x) and Y=0.27e~(0.46x) The baculum as an age and a taxonomic indicator is discussed. |
