Thecate forms; the body is Family _Tintinnidæ_ attached by a stalk to the cup; within the adoral zone is a ring of cilia.
The motile organs consist of an adoral zone of membranelles, which stretch along the left edge of the peristome and the front edge of the body.
The lines of cilia converge at the mouth, and at this region the cilia are somewhat larger and more distinct, thus forming a functional adoral zone.
The peristome is well-marked by the adoral zone, and upon its right border there is a row of cilia, and a similar row of cilia runs along the base of the oral membranelle.
The adoral zone and peristome agree with the details given in the family characteristics.
The adoral zone consists of powerful membranelles arranged in a continuous curve from the mouth to the extreme right frontal margin.
Membranelles very large and Genus _Actinotricha_ powerful; adoral zone not continued to mouth; 5 anal cirri
The region surrounded by the adoral zone is frequently drawn out into an anterior process, occasionally bearing a pigment mass.
