放射虫(Nassellaria，Radiolaria)的内部骨骼结构形成于个体发育的早期阶段，是超属分类的主要标准之一。它的详细知识也代表了一些属的分类学的结构基础。为了正确地使用它，一个新的描述内部骨骼结构的术语被用来描述一些长头鼻龙的大头。用这个新术语描述了新生代至近代的8个新种，它们分属于冈氏亚纲、丽氏亚纲和石龙纲，其中包括4个新种。此外，在初步骨架结构的基础上，作者阐明了该属的超属分类，即冈氏菌属(Gondwanaria Petrushevskaya)、李氏藻属(Lipmanella Loeblich)和塔潘属(Tappan)。
Internal skeletal structure of Nassellaria, Radiolaria forms during the early stages of ontogeny and is used as one of the main criteria of suprageneric classification. Its detailed knowledge represents also the structural basis of taxonomy of some genera. In order to use it properly a new descriptive terminology of the internal skeletal structure is developed for some large-cephalis bearing nassellarians. Eight Cenozoic to recent nassellarians assigned to three genera, Gondwanaria, Lipmanella and Lithomelissa including four new species, are described using this new terminology. Furthermore, on the basis of initial skeletal structure, the author clarifies the suprageneric taxonomy of genera, Gondwanaria Petrushevskaya and Lipmanella Loeblich and Tappan.
