摘　　要：贵州剑河八郎松山"清虚洞组"中上部布尔吉斯页岩型生物群共有50多属,其中含有刺细胞动物帐篷螺Scenella,1相似种:Scenella cf.radians。相似种较凯里组产出Scenella cf.radians放射线较粗,线间距稍大。"清虚洞组"Scenella的发现是继凯里组首次发现Scenella之后,本地区寒武系地层中Scenella又一次产出它的发现不但为剑河生物群刺胞动物增添了一个新的内容也为剑河地区寒武系Scenella的演化提供了宝贵的材料。There are more ghan 50 genera in The Burgess Shale type burgess bioca of the upper part of the Tsinghsutung Formaition,at Songshan,Balang Viuage,Jianhe country,Guizhou Province,inclade the similar species of radians which yielded by the Kerry group,the Similar speeies＇ radioactive rays in thicken,and the distance between the radioactive rays is Little bigger,The discorery of Tsinghsutang Formation＇s Scenua is the othen ortput of Scenella in Cambrian strata in this area,this disoovery not only added a new content for cnidarian of Jianhe biota,but also provided valuable materials for the evolution of Scenolla in Cambrian system of Jianhe area.
