【摘要】 <正> 关于黄河的研究,可追溯到我国先秦时代,一般认为黄河上源分别由发源于巴颜喀拉山支脉各姿各雅山北麓的卡日曲(Kar Qu)和发源于约古宗列曲盆地西南隅的南侧山地的约古宗列曲(Yoigilangleb Qu)及发源于玛(王甬)滩北部查哈里山的扎曲(Za Qu)等3条河流构成。以往都以约古宗列曲为黄河正源,1978年8月我国在西宁召开黄河河源和扎陵、鄂陵湖的科学讨论会,确定卡日曲是正源。但是关于黄河源头地区和星宿海的鱼类,更多还原

【Abstract】 This paper presents ten species of fishes including one new; species, collected from the Sources of the Huanghe River, namely the Kar Qu (卡日曲, 34°48’N, 96°24’E) and the Yoigilangleb Qu (约古宗列曲, 35° N, 96° E), and the Cocta Lakes (星宿海, 35° N, 96°42’E, Sea of Stars or Sing Su Hai), China, in June 1985 by the authors.1.

Chuanchia labiosa HerzensteinEight specimens collected with G. eckloni Herz., standard length 150-224mm.4. Platypharodon extremus HerzensteinTwo specimens collected from the Yoigilangleb Qu, standard length 252 and 285mm.5. Triplophysa pseudoscleroptera (Zhu et Wu)Specimens 26, collected from the Yoigilangleb Qu and the Cocha Lakes, standard length 49- 180mm.6. Triplophysa siluroides (Herzenstein)One specimen collected from the Cocha Lakes, standard length 186mm.7. Triplophysa kungessana (Kessler)Two specimens, one collected from a small lake of the Source of the Kar Qu, another from the Cocha Lakes, standard length 72 and 101mm.8. Triplophysa leptosoma (Herzenstein)Seven specimens collected from the Upper Yoigilangleb Qu, standard length 43- 93mm.9. Triplophysa alt ice ps (Herzenatein)Specimens 31, collected from the Upper Yoigilangleb Qu and the Cocha Lakes, standard length 46-81.5mm.10. Triplophyta obtasirostra sp. nov. (figs. 1-5)Holotype: No. 856031, ♀, standard length 89mm, collected from a small Lake of the source of the Kar Qu in the sources of the Huanghe River, in June, 1985.Paratypes: No. 856032 and 856082-856086, 6 specimens, standard length 28-90mm, collected with the holotype.The type specimens are deposited in the Northwest Plateau Institute of Biology, Academia Sinica.D. iii-7; A. ii-5; P. i-9-10; V. i-6- 7. Gill-rakers in inner row 16 and 17. Vertebrae 41.Diagnosis: A distinctive member of Triplophysa which differs from all other species in this genus by its rostral character: it is wider, thicker and shorter than that of all other species of this genus. This new species resembles Triplophysa dor-sonotata (Kessler) (=Ncmachilus dorsonotatus Kessler), but may be distinguished by the character as shown in the following table.更多还原
