NORTH AMERICAN EARLY TERTIARY BRYOZOA.

Discofascigera ( Defrancia ) exaltata Waters, 1884. Miocene of Australia. 
Discofascigera (Defrancia) brendolensis Waters, 1892. Priabonian. 
Discofascigera (Discotubigera) actinoides Manzoni, 1878. Miocene of Europe. 
Discofascigera ( Supercytis ) digitata MacGillivray, 1895. (-T elopora.) 
All these species are extremely rare. Their ovicells have never been observed. 
We therefore consider D’Orbigny’s genus as amended by Gregory, as a zoarial 
form and we describe it here for convenience in determination. There is no 
evidence to show that it is a member of the Frondiporidae.

“Fascigeridae with a massive zoarium, which develops from a small cup- 
shaped disk. The zooecial groups in the adult are long, and form irregularly 
sinuous series, which may be so crowded that the zoarium becomes massive. Aper- 
tures all on the ends of the zooecial bundles.” (After Gregory, 1909.) 
Genotype. — Apsendesia cristata Lamouroux, 1821. 
Range. — Jurassic- Cretaceous. 
This is a zoarial form in which the ovicell has not yet been discovered. 
Subdivision RECTANGULATA Waters, 1887. 
The ovicell is developed perpendicularly to the terminal zooecial axis between 
the peristomes and not between the tubes.
