42 REMARKS ON THE FAUNA OF THE 
the one band is a repetition of the other through the influence of an 
anticlinal fold or a dislocation. Both out-crops dip to the south- 
eastward. 
From the more northern out-crop (which we shall call A?) we 
have obtained Orthis 1, Leptena 1, Camerelia 1, Lingula 2, Discina 1, 
Agiostus 3, Conocepialites 1, Arionellus 4, Dikelocephalus 6, Bathy- 
urus 4. Fyom the more southern out-crop (which we shall call A$) 
we have Dictyonema 1, Orthis 2, Leptenal, Strophomene 1, Camerella 
Cyrtodonta (?) 1, Murchisonia 3, Pleurotomaria 7, Helicotoma 2, 
Straparollus 2, Capulus 2, Agnostus 1, Bathyurus 4, Chetrurus 2, 
Amphion. From a third out-crop, which is still farther southward, and 
supposed to be another repetition of tne same band (which we shall call 
_A*) we have Orthis 1, Camerella 1, Asaphus (A. Illenoides) 1, 
Bathyurus 1. Tracing A? or A® round the extremity of a synclinal, 
and finding occasional indications of the fossils of A? and A®, we 
arrive at a position on the south side of the synclinal. We shall call 
the position P. Here the band A? or A’ ends, but a bed of sand- 
stone a little above it is traceable over an anticlinal to a junction with 
a conglomerate band lower than A? or A$’, shewing that A? or A$ 
must merge into it. Call this A1. In this we have dsaphus (A. 
Tilenoides) 1, Menoecphalus (M. globosus) 1. These two series 
occur in the same fragment of rock. Of all these fossils, 1 Orthis is 
common to A®, A? and A*; 1 Leptena, 1 Camerella, 1 Lingula, 1 
Agiosius, and 1 Buihyurus, are common to A? and A®; 1 Asaphus 
is common to A? and A}. 
The dip at P is to the south-eastward, and therefore an inverted 
dip. North-west of this, and therefore above it, at such a distance as 
would give a thickness of between 200 or 300 feet, we have a band of 
shale with nodules of limestone, the nodules made up of other rounded 
masses in a matrix holding fossils, many of them silicified. From a 
few of these compound nodules we have obtained Orihis 11, Lepteena 
1; this band we shall eall B!, A band like this oceurs about half a 
mile or more to the south-westward. It may bea higher band, or it 
may be the same band, but we shall call it B2. From this we obtain 
Crinoidea ‘columns) 3, Orthis 1, Camerella 1, Navtilus 1, Orthoceras 
1, Leperditia 1, Trilobites (2 genera undetermined) 2. In another 
position to the south-east, on the south-east of the same anticlinal 
previously mentioned, we meet with a conglomerate band supposed to 
be the same as B? ; but, in case it should be different, we shal! call it
