40 feet below the top of the ClifPs of Moher ; some 20 feet above this 

 band, fossils are in a gray shale with nodules, but seem rarer. The 

 nodules are, however, sometimes crammed with minute GoniatiteSj 

 which I have not been able to determine. I think these bands are 

 probably identical with those seen in the Puffing Hole at Kilkee. 



The Survey mentions the occurrence of the same beds on the opposite 

 shore of Liscannor Bay, north of Rineen House. 



Area of Corofin and Ennis, — Good sections of the junction between 

 the upper bed of the Carboniferous Limestone and the shales are to be 

 seen round Kilfenora. Tliere is a good section a quarter of a mile 

 north of Ballyshanny House, as was noted by the Geological Survey. 

 Here the shales contain bullions with Goniatites exactly similar to the 

 section near Lisdoonvarna. 



The Eiver Fergus, flowing almost due east, reaches the junction of 

 the shales and limestone a little east of Kiltoraght Glebe house ; 

 and though the actual junction is not visible, the calcareous shales a 

 few feet above the junction contain — 



Posidonomya memhranacea. Pterinopecten papyracem. Goniatites. 



Plant-remains were seen in the river further west in beds which 

 must lie some distance above those at the watersink of the Fergus. 

 Another good section of the junction of limestone and shale is seen at 

 Yigo Cave. Here the beds are horizontal ; and the lower beds of the 

 shale series consist of black calcareous shales and thin limestones, said 

 by the Survey (p. 141, op. supra cit.) to abound in fossils ; but I was 

 not fortunate enough to obtain any. 



One mile south of Vigo Cave, at Adelphi, the upper beds of 

 the limestone form a cliff which is capped with black shales. The 

 shales can be examined for some extent in a stream-section about 

 a quarter mile south of the house. These contain the usual charac- 

 teristic fossils. Good sections of the shales are to be seen in the 

 road which skirts the western shore of Inchiquin Lake, and also in, 

 small streams south of the road from Willbrook to Corofin. 



At Ennis, the upper beds of the limestone contain a blue bed 

 crammed with specimens, often rolled, of a small variety of Productus 

 giganteus ; and above the limestone come the shales on the road to 

 Coor spa well, said by the Survey to contain numerous Goniatites 

 and Posidonomya. The shales are seen in the well itself, and in the 

 bank of the River Inch below the cottage opposite the well.
