Diagnosis. 
Cyclostomata Tubulata with simple tubular zooecia. The zooecia 
are monomorphic and long. They occur in bundles, and the 
apertures open in clusters on the sides or surface of the 
zoarium. Zoarium encrusting, cylindrical, or dendroid. 
Affinities. 
This family begins in the Weisser Jura of Wurtemberg, but is 
first well developed in the Cretaceous, after which it gradually 
becomes less important. 
The Osculiporidae are allied to the Theonoidae, but differ by the 
apertures being in groups and not in linear series. The zoarium is 
an encrusting band in Filifascigera, a simple and broad encrustation 
in Lopholepis, nodular and massive in Multifascigera, a compound 
group of radial tufts in Racliofascigera, and cylindrical in Cyrtopora. 
The Osculiporidae have a series of zoarial forms corresponding to 
the chief modifications in the simple Tubulata. Thus — 
Filifascigera corresponds to Prohoscina.
