在马里兰州、密歇根州和怀俄明州发现了一种新的异养鞭毛虫。鞭毛虫居住在由相互缠绕的原纤维构成的网状结构的洛里卡内，外表面嵌有钉状刺。生物体“斜倚"在洛里卡内，腹面向上，有两个异动鞭毛，两个鞭毛都不具鞭毛体。一根鞭毛向上，另一根在身体的腹侧呈拱形。细菌的摄入发生在细胞的左后半部分。该生物体通过一系列规则间隔的细胞质桥固定在右后侧的洛里卡上，并通过类似于在某些双孢子虫中发现的“languette细胞质”的细胞质附属物固定在细胞的左前侧。细胞的右侧隆起，形成扁平的唇缘，外缘由一条微管加强。新的鞭毛虫有线粒体与管状嵴和缺乏高尔基体。创建一个新属以适应本文所述的新鞭毛虫和钟形组鞭毛虫。提出了一个新的科，包括新属和Histiona。
A new heterotrophic flagellate has been discovered from sites in Maryland, Michigan and Wyoming. The flagellate resides within a lorica constructed of a meshwork of intertwined fibrils with the outer surface invested with nail-shaped spines. The organism ''reclines'' within the lorica with its ventral aspect directed upward, and has two heterodynamic flagella, neither of which bears mastigonemes. One flagellum is directed upward and the other is arched over the ventral aspect of the body. Ingestion of bacteria takes place al the left posterior half of the cell. The organism is anchored to the lorica on the fight posterior side by a series of regularly spaced cytoplasmic bridges and at the left anterior of the cell by a cytoplasmic appendage similar to the ''languette cytoplasmique'' found in some bicosoecids. The right side of the cell is raised into a flattened lip with the outer margin reinforced by a ribbon of microtubules. The new flagellate has mitochondria with tubular cristae and lacks a Golgi. A new genus is created to accommodate both the new flagellate described herein and Histiona campanula Penard. A new family is proposed to include the new genus and Histiona.
