摘要: 大家鼠在国内的亚种分化迄今并未定论,争议的焦点主要反映在:1)socercaraco等亚种如何划分。Allen(1940)将从河北至甘肃,四川,云南,福建的大家鼠视为scoer。Ellerman et al.(1951)却认为除福建外我国大陆上的大家鼠均属caraco,而socer则为异名;2)东南部的大家鼠,Howell(1929)认为广州、厦门、福建标本应订socer;Allen(1940)也将福建标本订为 socer,但指出东南部大家鼠值得进一步研究;Ellerman et al.(1951)和Dan Van Tien(1966)却都主张福建、广东标本应属norvegicus;3)海南岛的大家鼠尚未订亚种(黑田长礼,1940)。 本文所用标本473号,成体和亚成体,随机取自全国23个省区,各省区标本数目分别列于表1。用数理统计方法对比不同类群间的性状差异,从而研究其地理变异性。

Abstract: This paper deals with subspecific differentiation of Rattus norvegicuss Ber-kenhout in China, not including that of Taiwan province.Amoog 473 specimens which were sampled at random, 49 specimens were collected from Guangdong, including Hainan Island; 135 specimens from Hebei, Liaoning, shandong and northern Jiangsu; 136 specimens from Heilongjiang and jilin; and 153 specimens from Gansu, Ningxia, Inner Monggol, Shanxi, Shaanxi, Sichuan, Guizhou, Yunnan, Hubei, Zhejiang, southern Jiangsu, Jiangxi and Fujian. A comparison of the body measurements and the cranial measurements of the above four groups of the samples shows they belong to R. n. norvegicus, R. n. humiliatus, R. n. caraco and R.n. socer respectively. A key to these four subspecies is given in text.
