SADIOPORIDJE. 
BIMULTICAVE A, d’Orbigny, 1853. 
[Bry. Cret. p. 982.] 
Diagnosis. 
Radioporidse with a compound zoarium growing as a massive 
lamellar incrustation. The zooecia are arranged with their 
apertures in radial groups, which are slightly raised and are 
elliptical in shape, and have multiserial apertures. These 
sub-colonies are widely spaced, wdth wide margins of cancellate 
tissue. 
Type Species. 
Bimulticavea variabilis, d’Orbigny, 1853. Senonian : France. 
Afeinities.

Char. — Zoarium large, massive; Goldfuss’ specimen is 45 mm. long by 18mm. 
wide, with radial groups up to 6 mm. across. Each group has about eight 
spindle-shaped raised radial groups, with biserial apertures. 
Distrib. — Cenomanian — Griinsand : Essen. 
Arr. — This species was founded by Simonowitsch, who gave a long description of 
it, but his specific name goldfussi was preoccupied for an Oligocene species by 
von Reuss.
