摘要：法国南部Montagne Noire地区Roque Redonde的密西亚苔藓虫区系包括38种苔藓虫，其中12种为胞孔虫，2种为密孔虫，6种为隐孔虫，18种为窗孔虫。其中新属9种，分别为：tolokonnikoae fisstulipora n. sp、Dybowskiella rotunda n. sp、Dybowskiella piriformme n. sp、Eridopora suarezi n. sp、Volgia deftera n. sp、Cystodictya gallensis n. sp、Megacanthopora enodata n. sp、Fabifenestella macrofenestrata n. sp、Baculopora redondensis n. sp。此外还新属1个新种。此外，还鉴定出23种具有欧亚大陆和北美洲密西西比系特征的高卢gorjunnopora gallica n. gen, n. sp.。苔藓虫种类表现出不同的古地理联系。最接近不列颠群岛的密西西比（Visean）和俄罗斯平台。此外，与德国、乌克兰、西班牙、库兹涅茨盆地、北美和哈萨克斯坦的密西西比地区也有一定的联系。所研究的苔藓虫组合主要以微妙的生长形式为代表，表明一个平静的水环境。
ABSTRACT A bryozoan fauna from the Mississippian (Visean) of Roque Redonde (Montagne Noire, southern France), contains 38 species (12 cystoporates, 2 trepostomes, 6 cryptostomes [rhabdomesines], and 18 fenestrates). Of them 9 are new: Fistulipora tolokonnikovae n. sp., Dybowskiella rotunda n. sp., Dybowskiella piriforme n. sp., Eridopora suarezi n. sp., Volgia deftera n. sp., Cystodictya gallensis n. sp., Megacanthopora enodata n. sp., Fabifenestella macrofenestrata n. sp., and Baculopora redondensis n. sp. Beside them, one new genus with a new species is established: Gorjunopora gallica n. gen., n. sp. Furthermore, 23 species characteristic of the Mississippian of Eurasia and North America were identified. The bryozoan species show various palaeobiogeographic connections. The closest connections are to the Mississippian (Visean) of the British Isles and the Russian Platform. Moreover, some connections to the Mississippian of Germany, Ukraine, Spain, Kuznets Basin, North America and Kazakhstan can be traced. The studied bryozoan assemblage is represented mainly by delicate growth forms and suggests a calm water environment.
