Generic (llagnosis. — "The new subgenus Ct'ai^jjedophyllia is sepa- 

 rated fi'oni (>nt.phalo2)h.ijlUa b}^ possessing- a primitive septum ( TJi'Hep- 

 hiiii) and liorizotital endothecal dissepiments."

 XLlll, p. 65, pi. VII, tigs. 10-M, 22, text tig. 15, p. 15. 



Volz referred three species to this subgenus, namely: Axosmilia 

 (ilpina Loretz, Ci'(iKpedoi)hyllia erlstata^ new species, and (JnqjJiah)- 

 plnjllUi graeilis Lauhe, designating no type-species. As Volz lays .so 

 much stress on the " Ur septum ^'^^ I have selected as the genotype the 

 species for which the " Urseptum'" is iigured (p. 15, fig. 15). How- 

 ever, the horizontal dissepiments appear to be more typically devel- 

 oped in Cra.Kpedopliyllia gracilis (Laube) Volz. 



Dhfrihidion. — Triassic, St. Cassian ])eds, south Tyrol.

Origined d lag tics! h <>f famUy. — '" Madreporaria Fungida simple or 

 colonial. Septa ti'ahecuhitc and fenestrated. Synapticula small. 

 Dissepiments absent. Wall indistinct." 



The family nuist l)e extended to include genera in which dissepi- 

 ments exi.st. 



Gregory's Mlcrosolenidse^''' becomes an exact synon3'm. His defini- 

 tion is " Simple or colonial Fungida in which the septa are palissades 

 of more or less vertical, disconnected, regular, or irregular trabecular." 



Four genera, Antd)racki^Ov\Agx\y^ Trochophlegma Gregory, Cyclo- 

 l/tes Lamai'ck, and Trocliurxa Etallon are placed in this family.
