摘　　要：对中国西部(新疆和西藏)原定名为绿蟾蜍Bufoviridis的27个居群进行了形态学比较研究,同时与产于邻近地区的Bufodanatensis(土库曼)、Blatastii和Bstomaticus(克什米尔)的3种蟾蜍标本或原始描述作了对比。我们赞同Borkin等(1988)的研究结果,并将新疆各地原定名为绿蟾蜍Bviridis中四倍体的各居群(包括准噶尔戈壁)统归为Bdanatensis。同时将新疆和西藏的各居群分为4个类型,即以新疆乌鲁木齐、若羌、塔什库尔干和西藏札达为代表的4类,它们的形态特征互不相同。现根据形态和地理环境的差异将新疆地区标本分为3个地理亚种,即分布于天山以北的达纳特蟾蜍指名亚种BddanatensisPisanetz,1978,分布于天山以南的南疆亚种BdpewzowiBedriaga,1898和分布于帕米尔高原东部的帕米尔亚种Bdtaxkorensis,subsp.nov.;而西藏阿里札达者应为一新种,即札达蟾蜍Bufozamdaensis,sp.nov.。对新种和新亚种进行了描述。In this paper,morphologic characteristics among 27 populations of original green toads Bufo viridis from west China were compared.In meantime,their characters were contrasted with the three toads of the Turkmen and Kashmir from adjacents areas, Bufo danatensis,Bufo latastii and Bufo stomaticus (Kashmir).The results show that they may be divided into 4 types which differ from each other in morphologic characters (Table 1).We agree to the suggestion made by Borkin et al .(1988) that the tetraloid toads from Xinjiang area are temporarily placed in Bufo danatensis .Now this species includes 3 subspecies in Xinjiang area: Bufo d danatensis Pisanetz,1978; Bufo d pewzowi Bedriaga,1898; Bufo d taxkorensis subsp.nov..The toad from Zamda,west Xizang (Tibet) is considered to be a distinct species, Bufo zamdaensis sp.nov.. Bufo zamdaensis Fei,Ye and Huang,sp.nov.(Fig.1) Holotype:No.CIB?760085,adult male,type locality:Zamda (Tzada) County (79°80′E,31°50′N),Ngari (Ari) Prefecture,Xizang (Tibet),altitude 2?900?m;July 2,1976 collected by Chang Rong zu. Paratypes:4 (Nos.CIB?760086-0089),3 subadults (Nos.CIB?760090-760092),collected with the holotype. Diagnosis:This new species is similar to Bufo stomaticus Lutken,1863,but differs from the latter in:1)parotoid small,long slight larger than broad;2)tympanum small,1/3 diameter of eye;3)palmars large,inner one slight smaller than outer one;4)internal vocal sac of male without dark colour;5)frontoparitals twice as long as broad,with a fontanelle.The latter can be distinguished in:1)parotoid large,elliptical,about three times as long as broad;2)tympanum large,2/3 diameter of eye;3)palmars small,and inner one much less outer one,about 1/2 outer;4)frontoparitals lacking a fontanelle;5)male with a dark internal vocal sac. Bufo danatensis taxkorensis Fei,Ye and Huang,sub sp.nov.(Fig.2) Holotype:No.CIB?74SI0177,adult male,type locality:Taxkorgan(37°40′N,75°12′E),Xinjiang,altitude 3?120m?;June 11,1974 collected by Huang
