As Cretaceous species previously placed in <i>Bigenerina, Siphotextularia,</i> and <i>Textularia</i> differ from typical Cenozoic representatives of these genera in having solid non-canaliculate walls, 16 species from the Fredericksburg and Washita Groups (Albian-Cenomanian) of Texas and Oklahoma have been restudied. The new genera <i>Heterantyx</i> with type species H. <i>antonovae</i> sp. nov. and <i>Quasispiroplectammina</i> with type species <i>Spiroplectammina longa</i> are assigned to the family Spiroplectamminidae. A new family Textulariopsidae is proposed for basically biserial taxa with solid walls and includes <i>Plectinella, Textulariopsis,</i> of which two species <i>T. lechriosa</i> and <i>T. texhomensis</i> are new, the reinstated genus <i>Bimonilina,</i> with a new species B. <i>reciprocata,</i> and three new <i>genera, Aaptoioichus, Haimasiella</i> and <i>Minyaichme.</i>
