and altered slates, forming part of the bedded series restii)^ on 

 the limestones, as seen in the cliffs nearer Tramore. Sections of the 

 cherty rocks reveal traces of radiolaria. Dr. G. J. Hinde, who has 

 kindly examined the sections, is, however, unable to say definitely 

 that radiolaria are present, though he admits the close resemblance 

 of the rock to a radiolarian chert. 



Eeturning to the shore and south side of Lady Elizabeth's Cove, 

 we find that it is principally composed of the diabase- sheet, but in 

 contact with it above is a small exposure of baked and altered black 

 slates which, just at their junction with the diabase, contain grapto- 

 lites. Some were collected here by the Survey officers in 1865, and 

 are recorded in the Memoir in the list of fossils. They comprise 

 the following forms : — 



Callographos Salteri, Hall. Bendrograptits sp. ? 



Climacograptus hicornis, Hall, Didymogra'ptni^ sp. 



cf. teretiu^cuhis, His. Bicellograptus sp. 



CanograpUis gracilis, Hall. 



Recently I have myself collected the following^ at this spot : — ■ 



Diplogra'ptus foliacens, Murch. [ Dicellograptus sp. 



Cryp'fogra'ptus tricornis, Carr. | 



A fault shifts the limestones seaward on the south side of this 

 cove, and with the diabase-sheet they form the cliff's till we come 

 to a small cove just north of the Ladies' Bathing-cove opposite the 

 rock of Carrigaghalia (fig. 8). Li this cove the black graptolite-

A = Intrusive sheet of greyish felsite [118 w]. 



B = Black shales with flaggy beds, baked near the contact with the intrusive 



rocks (Carrigaghalia Series). 

 C=-- Impure fossiliferous limestones (Tramore Limestone Series). 

 D = Coarse dark green diabase. 



shales dipping north- north-westward at 75° are found again, with 

 the limestones dipping below them regularly, and with an intrusive 

 felsitic sheet [118 w] piercing the former. A few thin, sandy tuff- 

 bands [641] and crushed felsites are interbedded among these shales,
