Affinities. This species agrees precisely in its zooecial characters 

 with the type form figured by Haime. The zoarium, however, 

 is discoid instead of very irregularly lobed. The difference may 

 therefore be taken as varietal.

 taper slightly towards the free end. 



Peristomes highly raised. Apertures circular. 



Gonocysts somewhat pyramidal.
