gen. nov.

Genus Bidderia  gen. nov.

" Clathrinida  with copiously branched and anastomosed choanocyte tubes covered by a well-developed cortex formed mainly by regular triactines measuring at least the double size of the spicules present in the choanosome. Frequently, the inhalant apertures are conspicuous, but show no ornamentation. The exhalant aquiferous system is represented by a well-developed atrium delimited by a membrane with no choanoderm, supported by a specific skeleton of triactines and/or tetractines. Sagittal spicules may be present in the subcortical region. The apical actine of the tetractines has no spines. Aquiferous system is solenoid."

Etymology. For George Bidder, in recognition of all his work on the taxonomy of Calcarea.
