view of the Ootatoor age of the limestone ; they 



consist of: — 



Corals. — 1 Species. 



Rhynclionella. — 1 Species. 



Ostrea. — 1 Species, elongated and plicated like O. larva, much 



resembling a species common in the Ootatoor Group. 



Fecten. — 1 Species : the large-ribbed species noticed at Tripatoor. 



Belemnites. — 1 Species, not determinable. 



I have already spoken of the bedded structure which is so distinct in 



the Cullygoody ridge, and which may be noticed

less strongly marked. At Cully goody, as may be 

 seen in the figure (Fig. 5), it is so marked and regular, (the strike 

 being coincident with that of the ridge and the dip away from the 

 gneiss,) that the limestone might be easily mistaken for a regularly 

 stratified deposit. That it is not so, there is, however, sufficient evi- 

 dence, even had we not the analogy of the limestone elsewhere to 

 induce scepticism on this head. In the first place, whenever the 

 lower part of the limestone is seen, whether at the ends or side 

 of the ridge, or in the breaks which occur in it at one or two 

 points, there is no trace of bedded structure, and the limestone is 

 seen to rest on an uneven, but, on the whole, nearly horizontal 

 bottom. The bedded structure occurs exclusively in the middle and 

 upper part of the ridge, only in the latter, where the ridge is low, 

 the beds or slabs are from 2 to 4 feet thick, and the amount of 

 their dip (frequently 12 to 15 degrees, occasionally as much as 30) 

 is perfectly incompatible with the horizontality of the base, to the 

 very irregular outline of which the strike in no wa}- conforms. Again 

 the homogeneity of the rock, of little value as positive evidence,
