do not appear in the section of shale which rests on the top bed of 

 Carboniferous Limestone exposed in the stream but the shales are 

 crammed with fossils. 



It appeared to me that GlypJiioceras diadema and its varieties 

 occur immediately above the limestone, Pterinopecten papyraceus 

 appearing a few feet higher. Also that the lowest 12 to 20 feet 

 of shales were fossiliferous, remains being rarer above. 



Further down the Kilmoon stream, at the place marked with a 

 on the 1-inch Geological Map, the section shows Carboniferous Lime- 

 stone at the base, with a few corals {Lithostrotmi)^ immediately 

 overlain by shales full of bullions, the latter highly fossiliferous. 

 (PI. iii., % 2.) 



The fossils are — 

 GlypJiioceras diadema. JD. diserepans. 



ditto with large Nomismoceras spirorhis, 



umbilicus and coarse ribs. Orthoceras acutum sp. nov. 



G. Phillipsii. 0. aciculare, 



Bimorplioceras Gilhertsoni. Posidoniella Icevis. P. minor. 



With black shales above, containing 

 Posidojiiella Icems. Posidoniella minor. Pterinopecten papyraceus. 



This section can be followed for some distance south, the beds 

 dipping at the same rate as the fall in the stream level, about 5° ; but 

 eventually the limestone floor disappears, and the section is continued 

 in the shales. 



A fine section is seen on the south of the road, and continued in 

 the gorge of the stream west of Gowlaun Bridge, Lisdoonvarna. The 

 shales on the upper part of the section are thin bedded, and black, and 

 apparently contain few or no fossils ; but following the stream west, 

 past the iron and sulphur springs, the limestone floor appears in its 

 bed with the fossiliferous shales resting on it. A similar section is 

 seen about 200 yards east of Gowlaun Bridge. 



At the Spectacle Bridge the base of the shales is again to be seen 

 on the north side of the River Aille ; and here the overlying shales are 

 crowded with fossils, and are full of fossiliferous bullions in the lower 

 part. Similar sections, rich in thje same fossils, occur in the Aille, 

 between Knockaquilla and Eoadford, where the stream passes on to the 

 limestone and soon sinks out of sight, to come to light again in fissures 

 in the outcrop of massive limestone to the north of Fisherstreet Bay ; 

 the dip is here south-east at 5°. The junction of shales and limestone 

 is unfortunately not seen at Fisherstreet ; but, standing on the limestone
