The zoarial form Fills pars a D’Orbigny, 1852, contains species showing several 
sorts of ovicells, particularly those pertaining to Tervia and Oncousoecia , but the 
great majority of the species show no ovicells. The two American species of 
Oncousoecia are precisely like Filisparsa in zoarial growth. To facilitate the de- 
termination we place this old genus at the end of this family and maintain it for 
the species showing no ovicells.
