Lorica widening somewhat belowthe edge, and rapidly compressed beneath, though not at onceclosing, but produced downwards to a point whence there is ashort pedicle. Length from the point to the orifice about twicethe width of the expanded margin. Animalcule nearly spherical,only occupying the upper half of the cup; tentacles formingtwo antero-lateral groups with about fourteen in each group;tentacles distinctly capitate, rather longer than the diameter ofthe animalcule.
