Among the Turbinolidae hitherto known there are only 2 genera Discotrochus and 

 Discocyathus M. Edw. & Haine both only known in a fossile state (from the tertiary period) 

 which have the peculiar disc-shaped Fungia-like form of our coral. The Fungiacyathus is 

 distinguished from both these genera by the absence of a columella, from the Discocyathus 

 also by the absence of the inner circle of lamellae (pali) and is hereby evidently most nearly 

 allied to the Ulocyatlni* arcticus a Turbinolide living on our coast, which however is suffici- 

 ently distinguished by (inter alia) its short conical or wedge-formed crooked pointed base, 

 and by the presence of a wall-leaf which is certainly not very much developed in height 

 though yet distinct, while in the Fungiacyathus it is entirely wanting. 



Our coral belongs to that sub-group (of the two in the family of the Turbiuolidse) 

 which M. Edw. & Haine call Turbinolinse, and which is distinguished from the other group 

 designated as Cyathinse by the absence of pali.
