MARINE BOUI.DKR CI.AY IN COUNTY CORK. 



BY T. MKlylvARD RKADE, F.G.S. 



WITH NOTKS AND I,ISTS OF FORAMINIPERA 

 BY JOSEPH WRIGHT, F.G.S. 



Having spent my summer holidays last year in the South of 

 Ireland, I took the opportunity of examining the nature and 

 the distribution of the drift deposits in a part of County Cork. 



This research was only incidental to other geological field 

 work, and was undertaken at the suggestion of Mr. Joseph 

 Wright, F.G.S. , who had hitherto failed to find Foraminifera in 

 the Boulder Clays from that region. 



My first impressions from the nature of the Boulder Clay met 



with were certainly unfavourable as regards the probability of 



its yielding Forams, or indeed any microzoa. Eventually on the 



south-west side of Clonakilty lyough, east of the embankment 



over the Cloheen strand, I observed on the margin of the 



lough a more favourable-looking yellow sandy Boulder Clay, 



packed in places with slaty- rock fragments. This drift yielded 



a fairly abundant amount of foraminifera, as the following 



report from Mr. Wright will show : — 



No. 2. B0UI.DKR C1.AY, Ci^ONAKiivTY.— Weight of clay, 24*8 oz., Troy. 

 After washing, fine, 9 oz. ; coarse, 8-5 oz. Foraminifera common. 



FORAMINIIfERA. 



Mlllolina sp. — One broken specimen. 



Tcxtularia sp. — One specimen. 



Bullmina pupoides, d'Orb.— One specimen. 



B. fusiformls, Will. — Very rare. 



B. marglnata, d'Orb.— Frequent. 



BoIIvina punctata, d'Orb.— Rare. 



B. plicata, d'Orb. — Rare. 



B. difforinis (Will.).— Rare. 



B. dilatata, Rss.— One specimen. 



Cassldullna laevlgatai d'Orb.— Frequent.
