Notes
Favella ehrenbergii and Coxliella annulata are two forms of the same life-cycle. When a trophont leaves its lorica (of the form Favella or Coxliella) without division, it reconstructs always a lorica of the form Coxliella; when it divides, the proter elaborates a new lorica of the form Favella, the opisthe keeps the original shell and eventually modifies it. A lorica-secretion activity exists then during the trophic life and may be used for the reconstruction of an entire lorica outside of division. The spiral would loricae named Coxliella do not constitute a genus, but are the convergence of the forms elaborated by quite different genera during one stage of their life-cycle.
