174 Mr. R. Griffith on Mr. Weaver's Paper relative 



unusually compact, the sandstone passes into quartz-rock, but 

 it still exhibits the calamites. 



In many localities the carboniferous slate includes beds of 

 limestone, which, together with the slate, contains fossils simi- 

 lar to those which occur in the lower beds of the carboniferous 

 limestone. This is the case at Blackball Head% on the 

 north-western extremity of Bantry bay; also at Brickeen island, 

 near Killarney; at Kenmaref'; at Clonea Castle on the coast 

 of the county of Waterford, south-west of Bally voil Head ; at 

 Goat island in Ardmore bay on the same coast; at Kilna- 

 mack, near Knocklofty bridge; on the south side of the valley 

 of the Suire above Clonmel, and many other localities. 



The following are a few of the fossils which occur in the beds 

 of carboniferous slate which are interstratified with the 

 limestone at the following different localities : 



Fossils which have been discovered in the carboniferous slate 

 beneath and interstratified with the admitted carboniferous 

 limestone at the undermentioned localities. 



Fossils which have been discovered 

 in the carboniferous alate beneath 

 and interstratified with the lime- 

 stone of Killarney and Cork Har- 

 bour, supposed by Mr. Weaver to 

 belong to the transition series. 



Ballinacourty, 

 Dungarvan Bay. 



Clonea Castle, 

 Dungarvan. 



Kilnamack, near 

 KnockloftyBridge,

 taining calamites.
