It cannot be denied that Pyrophyllia has some 

 characters reminiscent of the extinct Rjigosa, but it does 

 not seem possible at present to give it a resting place in 

 any of the families of these fossil corals. 



I consider that Guynia and Pyrophyllia should be 

 placed in a distinct family, the Guyniidae, and that this 

 family should be placed next to the family Turbinoliidae. 

 The genus Haplophyllia appears to me to be quite distinct, 

 and it may possibly prove to be but a stage in the growth 

 of a form like Dtiiicania, with which genus Gardiner 

 considers it to be identical.
