192 BETICULIPOE A . 



Diagnosis. Cyclostomata Dactylethrata with a branching zoarium 

 composed of a central lamina, upon each side of which are crowded 

 zocecia and dactylethras. The zooecia open only on one face of the 

 zoarium. 



Affinities. This family differs from the ClausidaB by having 

 the zocecia opening only on one side of the zoarium. It thus 

 occupies the same relation to the Clausidae in the Dactylethrata, 

 that the Idmoniidae do to the EntalophoridaB in the Tubulata.

Diagnosis. ReticuliporidaB in which the zoarium consists of long, 

 compressed branches, consisting of a vertical zoarial lamina, on 

 each side of which are many short, closely packed zocecia and 

 dactylethra3. The zoarium is erect, and may be retiform or 

 composed of radial branches.
