在属于裸足纲两个科 Chlamydodontidae 和 Dysteriidae 以及 Chono-trichida 目的纤毛虫中，宏核由两个不同但非常紧密并置的部分组成。一部分，这里称为“orthomerous”，包含脱氧核糖核蛋白的颗粒或微粒体和几个核仁；因此，它显示了普通类型大核的正常结构。另一部分，“副生殖”，包含显然分散在同质核淋巴中的DNA，此外还拥有几个核仁和脱氧核糖核蛋白的内体。所讨论的三类纤毛虫密切相关，并且构成了非常发达的形态组合。它们的大核的“异质”结构必须被视为二次获得和“同质”类型的分化，“同质”类型是大多数其他纤毛虫大核结构的特征。
In ciliates belonging to the two gymnostome families Chlamydodontidae and Dysteriidae as well as to the order Chono-trichida, the macro nucleus is composed of 2 parts which are distinct but in very close juxtaposition. One part, here called "orthomerous," contains granules or microsomes of desoxyribonucleoprotein and several nucleoli; it thus shows the normal structure of a macronucleus of the ordinary type. The other part, "paramerous," contains DNA diffused, apparently, throughout a homogeneous karyolymph and possesses, in addition, several nucleoli and an endosome of desoxyribo-nucleoprotein. The three groups of ciliates under discussion are closely related and constitute an assemblage of forms remarkably developed. The "heteromerous" structure of their macronuclei must be considered as a secondary acquisition and a differentiation of the "homeomerous" type which characterizes the structure of the macro-nucleus in most other ciliates.
