Diagnosis. 
Cyclostomata Tubulata in which the zooecia are simple, open 
tubes. They arise from a small cupuliform or discoid base 
(the Pelagia or Defrancia stage). The zooecia are monomoqdiic 
and very long. The zoarium consists of bundles of parallel 
zooecia, and the apertures are in groups at the ends of the 
bundles. 
Affinities. 
This family is first represented in the Jurassic System by two 
genera, FascicuUpora and Apsendenia. In Fasciculipoy'a the zoarium 
consists of branching zooecial bundles, which keep apart, so that 
the zoarium is open and dendroid. In Apseyidesia the bundles arise 
from a small fungiform base, and are arranged in long linear series. 
The family becomes more important in the Cretaceous System, and 
d’Orbigny included thirteen genera in it; of these, however, five 
genera, viz., Cyrtopora, Osculipora, Filifascigera, Multifascigera, 
and LopJiolepis, are here referred to the family Osculiporidae, which 
was founded by ^larsson. 
Radiofascigera is either a confluent Actinopora or more probably 
one of the Osculiporidae {vide p. 52). Pefrancia, Broun, is a 
synonym of Apseyidesia} 
The family is nearly allied to the Osculiporidae, in which the 
apertures are in groups on the sides of the branches instead of 
being all terminal.
