摘　　要：对张录易等 (1992 )所建立的管状骨骼化石Qinella属进行重新修订 ,根据基本宏观特征、壳面装饰和壳壁套管式结构等将QinellashaanxiensisZhang ,LietDong ,1992和QinellalijiagouensisZhang ,LietDong ,1992归入SinotubulitescienegensisMcmenamin ,1985 ,而Qinella属征限定为管壳外表面光滑的多层壁套管式结构。对Chenella的属征进行厘定 ,建立ChenellaregularisZhangetHua一新种。根据口部特征的似吸盘状构造 ,建立蠕形动物—新属YudaiellaZhangetHua。The similarites of column in column structure of their multiply layered tube walls as well as their typified wall ornaments make it possible to transfer Qinella shaanxiensis and Q. lijiagouensis to Sinotubulites cienegensis. While the genus Qinella is retained, and delimited to the smooth walled multiply layered tubular fossils, also is of column in column structure. Chenella, however, can be readily distinguished from any other members of the tubular fossils by its single layered wall. A worm like structure with a circular sucker like structure in its anterior has been described for the first time, and ascribed to a new genus Yudaiella.
