The type specimens were obtained from the Miocene of Maryland, but

Description. The encrusting zoarium of this species may very readily 

 be recognized from all cyclostomatous bryozoa by the fasciculate zoce- 

 cia, arranged in groups of from two to five, arising from the center of the 

 broadest portions of the zoarium. 



This is a common and characteristic species of the Vincentown lime- 

 sand in New Jersey and Delaware. 



Occurrence. EANCOCAS FORMATION. Noxontown Millpond, Delaware.
