摘　　要：目前应用毛皮学知识对小型兽类的分类研究较少.笔者应用光学显微镜对四川分布的安氏白腹鼠(N.andersoni)、川西白腹鼠(N.andersoni)、社鼠(N.confucianus)、针毛鼠(N.fulvescens)4种白腹鼠臀部针毛形态结构进行观察,发现这4种鼠针毛上分布有不同的鳞片类型.通过对这些鳞片类型的观察及数据测量比较,发现鳞片类型有种的特异性,可作为这4种白腹鼠分类的有效指标之一.Recently, using the knowledge of fur for taxonomic study of small mammals is rarely seen. In this study, the microscopic characteristics of straight hair from the buttocks of 4 Niviventer species （ N. andersoni, N. excelsior, N. confucianus and N. fulvescens） distributed in Sichuan were observed, and different types of scales were discovered on these hairs. After observation and examination, the interspecific differences among the different types of scales were found, and these can be an effective index to identify the different Niviventer species.
