On the Puleontology of County Dublin. 181 
Fragments of shells were also observed at other places on the 
Dublin Mountains in similar deposits, the particulars of which are 
described by the Rev. M. H. Close in the article referred to, 
I'ragments of marine shells have also been collected from coarse 
sand a little to the east of Glennasmole, Townland of Corrageen, 
at about 600 feet above the sea level,* and form a conglomerate 
of drift pebbles, cemented together by Arragonite (Carbonate of 
Lime) a little south of Fort or Bohernabreena bridge. 
At Howth marine shells have been collected and described by 
Dr. Scouler from the gravel deposits there,t and Dr. Oldham 
gives a list of others from similar deposits at Killiney, in the 
County of Dublin, and Bray, County of Wicklow.} 
The following species were identified by Dr. Scouler from 
Howth :— 
Turritella (terebra) communis. 
(Turbo littoreus) Littorina littorea (Periwinkle. ) 
(Nerita littoralis) Littorina littoralis. 
Buccinum undatum, 
Cardium edule, 
Cyprina Islandica. 
Pecten varius. 
Those named by Dr. Oldham from Killiney, &c., being— 
Ostrea edulis. 
Tellina solidula. 
Pecten opercularis. 
Pullastra decussata. 
Nucula oblonga. 
Astarte (Gairensis) elliptica, 
Jorbula nucleus ! 
Saxicava rugosa, 
The only remaining fossils to notice are those of Mammalia, 
found in Pleistocene deposits of freshwater shell marl immediate- 
ly below the Peat Bogs. 
The great Irish deer, Megaceros Hibernicus, so fr equently found 
in Shere deposits in Ireland, evidently existed formerly in con- 
siderable numbers in the neighbourhood of Dublin. Professor 
Oldham, in a paper read before the Geological Society of Dublin, 
in 1847,§ records the discovery of the remains of at least thirty
