Cava is a synon 3 ’m) or Sulcocava. The name Cerioporina was 
proposed by von Hagenow for a group and not a family, and 
he did not in his monograph attempt to define families. The 
family Cerioporidea proposed by Marsson in 1887 appears to be 
the most convenient for this series of genera. 
The number of genera to be included in this family is uncertain. 
It includes several of d’Orbigny’s family, the Cavidae, exclusive, 
however, of Cava and Sulcocava and their allies. The second 
species which d’Orbigny included in Cava (viz. C. suhcompressa) 
is, however, a Ceriopora (B.M. Cat. Jur. Bry. p. 200). The 
true Ceriocava, which includes the type species of Cava and 
its young stage Reptonodicava, should be excluded, the typical 
species of that genus being Entalophorids with trumpet-shaped 
zooecia.^ The Cretaceous Ceriocavcc of d’Orbigny are branched 
species of Ceriopora ; but the difference between the thick 
branches of this genus and the tuberous processes and finger- 
shaped forms of the massive species does not seem of generic value. 
The series of Cretaceous Cerioporids may be grouped as follows : — 
ReptomuUicava. — Zooecia short and zoarium multilamellar. The 
genus corresponds to Reptomultisparsa in the Berenicea series. 
Defrayiciopora. — Zoarium of several superposed, saucer- shaped 
sub-colonies. 
Ceriopora. — Zoarium massive or branched, with long zooecia.
