This paper gives a description of three new subspecies of the Callosciurus erythr-aeus (Pallas) , collected from the Qinling mountains in Shaanxi,the Dabashan mountains and the Wulingshan mountains in Sichuan from November 1980 to December 1986. The type specimens arc deposited in the Biology Department of Northwest University in China.
1. Callosciurus erythraeus qinlingensis, subsp. ncv.
Holotype: No. 80008, an adult male, collected on 3 November, 1980, from Shanyang county located in the south of the Qinling mountains in Shaanxi Province, at an alt.of 620m.
Allotype: No. 80007, an adult female, collected on 4 November, 1980. from the same locality as holotype, at an alt. of 610m.
Paratype: No. 80001, an adult male, collected on 2 November. 1980, from the same locality as holotype, at an alt. of 610m.
Diagnosis: This new subspecies is related to C.e.styani in the size of the body and skull, but it generally differs from C.e. styani by the following characters: 1). The ventral pelage is a greyish-white coloration, instead of being cream buff or pale ochra-ceous buff. 2). The dorsal pelage of the tail is a greyish-olive coloration, which is paler than that of C.e. styani in brownish-yellow-olive.
2. Callosciurus erythraeus dabashanensis, subsp. nov.
Holotype: No. 860023. an adult male,collected on 28 November, 1986, from Wanyuan county located in the south of the Dabashan mountains in Sichuan Province, at an alt. of 650m.
Allotype: No. 860022, an adult female, collected on 27 November, 1986, from the same locality as holotype, at an alt. of 640m.
Paratype: No. 860024, an adult male, collected on 25 November,1986,from the same locality as holotype, at an alt. of 800m.
Diagnosis: This new subspecies is clcse to C.e. qinlingensis in the ventral pelage lacking brownish or reddish tone, but it differs from C.e. qinlingensis by the following characters: 1). The pelage is much darker with the dorsum having a uniform obscure tawny-olive coloration and the back of the hands and feet like the dorsum in coloration. 2). The back of the ears has black hair.3). The ventral pelage is 'yellowish-grey. 4). The tail is longer than that of C.e, qinlingensis, and the terminal black region is longer and more evident, about 30-50mm in length. 3. Callosciurus erythraeus wulingshanensis, subsp. nov.
Holotype: No. 86009, an adult male, collected on 11 December, 1986,from the Qian jiang county located in the north of the wullingshan mountains in Sichuan Province,at an alt. of 680m.
Allotype: No. 86007, an adult female, collected on 13 December,1986.from the same locality as holotype, at an alt. of 640m.
Paiatype: No. 860026, an adult male, ollccted on 28 December, 1986, from the same locality as holotype, at an alt. of 720m.
Diagnosis: This new subspecies is similar to C.e. castaneoventris in having a long subterminal white tipped hair on the posterior portion of the tail, but it differs from C,e, castaneoventris by the following characters: 1). Dorsally it is much darker than C.e. castaneoventris in its uniform mummy-olivt coloration. 2). The head and body length is longer than the tail. 3). The back of the hands and feet is black. 4). The back of tail is more bright-oolored than the dorsum, and the white region on the poste-rior part of the tail is about one fifth of the total length of the tail but one half for C e, castaneoventris.
