''III. Family LOPHOSERID.E. 



" (Sul)faiiiily Lo/ihoscrimr Edwards and Haime. ) 



'' Fuii«;i(la' ill wliicli the Willi is noitluM- perforated nor ecliinulate. 

 Syiiapticiila exist, l»ut not endothecal dissepiments. Septal lamina* 

 usually solid, but occasionally with ill-defined perforations, remote 

 from the bottom of the septa. 



"Very considerable changes have taken place in the old subfamily 

 of Milne-Edwards and Jules Haime, the LopJioserlnde^ owing to the 

 introduction of new genera and the elimination of old ones in conse- 

 quence of the necessity of founding the family Plesioporitidte. 



"There are two subfamilies — the LopJio.se ridm sinijyUeeM and Lopho- 

 nei'ldx aggregata;.^' 



"IV. Family AN ABACIAD^. 



"Madreporaria Fungida simple or colonial. Septa trabeculate and 

 fenestrated. Synapticula small. Dissepiments absent. Wall indis- 

 tinct." 



"V. Family PLESIOPORITID^. 



' ' Fungida with trabeculate and regularlj^ perforate septa. S^^nap- 

 ticula between the septal lamina^ in the interseptal loculi. Schleren- 

 chyma trabeculate. Dissepiments may or may not exist. Wall 

 existing or not, and imperforate. Epitheca may exist and be well 

 developed." 



M. Koby divided the Fungids described by him from the Jurassic of 

 Switzerland into two families, Tharanastreides and Microsolenides." 

 He unfortunately used the wrong species, TJiamnastrxa arachnoides^ 

 as the geno-ty])e of TJuuiDiastn^o. 



Freeh, in his Korallen der juvavischen Triasprovinz,* recognized 

 among his material two families of Fungids, Tliamnmirseidx, with two 

 subfamilies, TJiamnastraihuv and Astra^omorjjhinx^ and a new family, 

 Spongiomorphidm. Freeh was misled concerning the septal structure 

 of the real Thanniasti'xa. 



Ogilvie, in her Systematic study of the Madreporarian types of 

 corals,'" considered the Madreporaria Fungida of only family impor- 

 tance and recognized three sul)families, namely, Fanginse^ Thaiiina- 

 strminde^ and Lop)hoserinx. Her Thatunastrceinx, is based on Pratz's 

 misconception of Tliamncmtvdea. 



A decided advance in the classification of the Fungida was made by
