FORAMINIFERA IN IRISH GREENSAND. 



BY GEORGE C. GOUGH, A .R.C.SC.(l.OND.), F.G.S. 



Last summer, during a visit of the geological section of the 

 Belfast Field Club to Whitehead, I was struck by the suita- 

 bility of the "Chloritic Sands" there for "floating," and 

 brought home a sample, together with a sample of the "Yellow 

 Sands," in order to examine them for Foraminifera, As far 

 as I can gather there is no reference to the presence of such 

 organisms in these deposits, with the exception of Hume's 

 paperJ Here they are refernid to as being in the form of 

 glauconitic casts, not specifically recognisable. In the 

 Chloritic Chalk they were also found by him as recognisable 

 casts, the other reference being to a solitary Flabellina cordatai 

 accidentally found when dissolving glauconitic marl. By 

 floating I was able to obtain a large number of Foraminifera, 

 and there is no doubt that a thorough examination of these 

 deposits w^ould yield a great number of species. They are 

 preserved in calcium carbonate, and have become very chalk}^ 

 but can be recognised with a little trouble. Unfortunately I 

 have not sufficient time thoroughly to work them out now, 

 so I am just recording their presence in the hope that someone 

 else will be able to submit them to a thorough examination. 



In both the Chloritic Sands and the Yellow Sandstones 

 Texiularia globulosa and Globigevina cretacea are extremely 

 abundant. The following Foraminifera were easily recognised :
