rocks and succession at each locality, appears sufficient to account 

 for the slight modification in the relative abundance of some species 

 and for the appearance of some new forms. The Newtown Cove 

 beds have a somewhat different fauna, and must be considered 

 sepai-ately. 



The correlation of these impure limestones is not difficult when 

 we remember that they immediately succeed beds containing 

 a Glenkiln fauna. If we look at the succession in the South of 

 Scotland, we see the Balcletchie beds with a somewhat similar 

 fauna containing Hartfell graptolites, and the Hartfell Shales 

 immediately succeeding the Glenkiln Shales. Additional evidence 

 is afforded by the fact that some fossils of the Tramore limestones 

 are only known in Great Britain from the Balcletchie and associated 

 beds {Asaphus gigas, Cheiriirus gelqsinosiis, Porambonites intercedens), 

 while one species (Asaphiis gigas) is absolutely peculiar to the 

 Balcletchie beds. 



Certain species of the Tramore limestones are, however, peculiar, 

 and have not so far been found outside Ireland : — 



Amphion pseudo-articulatus. Fhacops truncato-caudatus. 



Cybele framorensis. Falceaster obtums. 



Fhacops Jamesi. 



This may be partly due to the fact that Ireland belonged to a different 

 but adjoining zoological province, and partly that the Tramore 

 limestones are not exactly on the same horizon as the Balcletchie

beds. The latter suggestion is rendered all the more probable from 

 the much closer correspondence of the fauna of the overlying 

 Newtown Cove beds with that of the Balcletchie beds. I would 

 therefore consider the Tramore limestones as corresponding with 

 only the lower portion of the Balcletchie beds of Scotland, and with 

 the whole or some portion of the underlying Benan conglomerate. 



3. These Newtown Cove beds are found immediately above the 

 impure limestones of the cliffs, and are well seen in the sides of the
