| 摘 要： | 箭囊海绵(Pharetronida)目可分为两个亚目:(1)串管海绵;(2)纤维海绵。纤维海绵骨骼是由骨纤构成,在骨纤内的海绵骨针由于重结晶作用而消失贻尽,但仍能识别出一些骨针的形态。Tabulozoan暂归入硬海绵内。本文描述的纤维海绵有以下各属:Peronidella sp., Peronidella sp.nov., Stellispongia sp.,对Tabulozoan也进行了描述和讨论。

| Abstract: | The Inozoan are generally included into Order Pharetronida as a suborder, which occurs very often as an important framebuilding organisms in Permian reefs, Lichuan county, West Hubei. Tabulozoan are temporarily regarded as a member of Sclerospongiae with some uncertainty, because primary siliceous spicules have not been discovered within their skeleton yet. Tabulozoan can act not only as main frame-building organisms, but also play binding role of encrusting some frameworks within reef rocks.Inozoan and Tabulozoan are widely distributed in Permian reefs, such as Wangmo county, Guizhou Province, Longlin county, Guangxi Province and Guangnan county, Yunnan Province in south China.The following genera and species of Inozoan Peronidella sp., Peronidella sp. nov., Stelli-spongia sp., and Tabulozoan are also described in the present paper. |
