Mr. Weaver on the 
to the mountain limestone of the northern and other parts of Eng- 
land, as well as of Wales. 
§ 180. It is not my intention to enumerate in full detail the 
petrifactions, which occur in this widely spread field of floetz lime- 
stone in Ireland. The subject is so extensive, that it might with 
greater propriety form the subject of a separate work. I shall con- 
fine myself to a few only ; remarking that, in most parts of the 
field, several of the petrifactions noticed above, as well as of those 
which follow below, may be casually met with. 
In the collection of Dr. Stokes, Professor of Natural History in 
the University of Dublin, from the King’s county limestone, may 
be ^observed, terebratula ornithocephala, terebratula obsoleta, am- 
plexus coralloides, orthocera lasvis, orthocera annulata, ( Sowerby ) 
anomites productus of Martin, helicina of Lamarck, madreporite 
junci lapidei, ( Parkinson,) And in a collection belonging to the 
same gentleman from Cloghran, within a few miles of Dublin, I 
have seen terebratula lateralis, terebratula biplicata, euomphalus 
pentangulatus, ( Sowerby ) turbinated madreporite, ( Parkinson ) 
and several species of anomites. 
In the limestone at Sutton, I have observed entrochites, ammo- 
nites, euomphalites, corallites, terebratula biplicata, terebratula orni- 
thocephala, anomites productus, several other species of anomites, 
madreporites, orthocera lasvis, Orthocera annulata, amplexus coral- 
loides, spirifer cuspidatus, ( Sowerby ). In the county of Limerick 
limestone I have also remarked, amplexus coralloides, terebratula 
biplicata, euomphalus pentangulatus, cardium hibernicum, ( Sower - 
By ) anomites productus, entrochites, &c. In other portions of the 
limestone field, have also been found, mytilites, pectinites, pectun- 
culites, tellinites, turbinites, trochites, belemnites, ostracites, patellites, 
and echinites, both the body and spines.
