DISCOFASCIGERA. 
31 
Diagnosis. 
Fascigeridge in which the zoarium consists of a single, unbranched 
bundle of zooecia ; the zooecia are short, and the zoarium is 
fungiform, consisting of a- short stalk, which rapidly expands 
above into a circular or subcircular disc, with a convex upper 
surface. 
Apertures crowded, and all on the upper surface of the zoarium ; 
they are either irregular or sub-quincuncial in arrangement. 
Type Species. 
Biscofascigera ligen'ensis, d’Orbigny. Senonian : France. 
Affinities. 
The zoarium has a similar form to that of the Befrancia stage 
of Apsendesia, which differs by the arrangement of the apertures in 
radial lines or ridges. The genus is allied to FascicnUpora, which 
differs by having a branching tufted zoarium. 
The genus was merged as a synonym of Befrancia by Eusk,^ who 
accepted d’Orbigny’ s species, B. cupula, as a form of the Befrancia 
lucernaria (Sars)^; but Sars’ species has its apertures along radial 
ridges, and thus differs from d’Orbigny’s two Cretaceous species. 
The two Bryozoa may, therefore, be quite distinct. Hamm^ 
reduced Biscofascigera to a synonym of Fasciculipora. 
The genus appears to me a convenient one. It survives into the 
Cainozoic, and is represented in the Middle Cainozoic deposits of 
Australia by a Biscofascigera exaltata (AYaters),^ from Mount 
Gambier in the State of South Australia ; by B. hrendolensis 
(Waters),® from the Miocene of Northern Italy, and also from the 
Miocene of Austria.®
