Affinities. The species agrees best among Jurassic species of the 

 genus in its pyriform zocecia with S. dichotomoides (D'Orbigny), 

 but the hippothoiform zoarium and long whip-like proximal 

 portions of the zocecia clearly distinguish it. Owing to the 

 imperfection of Phillips' figures, much uncertainty has existed 

 regarding it. The front walls are often broken away, giving the 

 specimen a Schizoporellidan aspect.
