Speaking of the corals generally, we have more affinitie 
Miocene forms than Pras other formation; but afew atin s rm

Foestis dis both of Europe and America; neither have we

shall shortly describe in the Transactions of this Society some few 
very characteristic Eocene genera of America, Cerato- 
trochus (C. fenestrata), which is both Miocene and Riana as it is 
th American and European. The commonest of our corals in 
the Muddy Creek is undoubtedly Deltocyathus viola, Woods and 
Duncan ; and of this Professor Duncan says it a greater 
resemblance, as far as shape is concerned, to the Plewrocyathi of 
the German Pnessanoral butit is a true Caryophyllia,* an * an a there-
