The gut is figured by Traustedt (1893) as apparently a compact "nucleus," but Apstein (1894, b) shows it in the embryo as a loop (fig. 23), but more compact than in any Cyclosalpa.

It shows (fig. 24) about as much asymmetry as the aggregated Gyclosalpa virgula. The pattern of the asym- metry is constant, except that in some individuals it is exactly re- versed. Ac

On the right side the interme- cn. en.
