Of the 13 species of corals, 4 (namely Lohopsammia cariosa, 

 Goldf., Madrepora Solanderi, Defr., JSolenastrcea Koeneni, Dune, 

 and >S'. gemmans, Dune.) are found in the Oligocene strata of the 

 Continent. I am indebted to Dr. Duncan for valuable information 

 upon this point. It is only right to point out that the study of 

 these corals led Dr. Duncan to the conclusion that the Brockenhurst 

 strata are the representatives of the Oligocene of North Germany, 

 and that this conclusion was arrived at by him quite independently 

 of the work of Von Konen upon the molluscan forms in the same 

 beds. 



Separated from the Brockenhurst series by about 300 feet of 

 estuarine and freshwater beds, we find the strata containing our 

 third marine fauna. This fauna is not represented, it is true, by so 

 large a number of species as either the Barton or the Brockenhurst 

 fauna ; but we have, nevertheless, sufficient evidence of its distinct- 

 ness from both of them, and data by which we can correlate the
