Diagnosis. 
Fascigeridae with a massive zoariiim, which develops from a small 
cup-shaped disc. The zocecial groups in the adult are long, 
and form irregularly sinuous series, which may be so crowded 
that the zoarium becomes massive. 
Apertures all on the ends of the zocecial bundles.

Apsendesia cristata, Lamouroux, 1821. Jurassic — Bathonian : 
England, France, and Germany.

Chau. — Zoarium nodular, with the bundles of zocccia arranged in sinuous series, 
which give the zoarium a meandriform aspect. The bundles of zooecia are 
somewhat regular, and occur as elliptical or triangular groups, which project 
on the obverse side of the erect sinuous lamina, of whicli the reverse side is 
covered by thick epizoarium.

Char. — Zoarium elliptical in section, with a considerable number of radial ridges, 
around a long central depression, the floor of which is imperforate. The 
apertures open along the top of the ridges and they are biserial, or rarely 
triserial ; each longitudinal row includes from two to eight apertures. Zoarium 
in the type-specimen 9 mm. long by 4’5 mm. wide, and with a little over thirty 
radial groups of apertures. 
Distrib. — Senonian — Maastrichtian : Fauquemont, Limburg.
