the Pamelia, from the upper layers of which ostracods, 
cephalopods, and a few tribolites may be collected. 
AYLMER AND QUEEN’S PARK. 
Beauharnots, Aylmer and Pamelia.—At Queen’s Park, 
on the shore of Lake Deschénes, and on either side of 
the wharf, there are outcrops of the rusty-weathering 
dolomite of the Beauharnois formation. By persistent 
search, gastropods and a few other fossils may be found, 
but as the fossils occur sporadically, it is not possible to 
name any particular locality from which they can be 
obtained. 
Just below the wharf at Aylmer is an outcrop of 
sandstone near the base of the Aylmer formation. This 
sandstone contains Camarotechia plena, Camarotechia 
orientalis, and Hebertella 1mperator. At another locality a 
low cutting in sandstone and shale shows numerous 
speciniens of Ctenodonta parvidens, Modiolopsis sowter1, and 
Lophospira billingst. 
A small excavation in the ditch to the right of the road 
and opposite the house of Mr. T. W. E. Sowter, indicates 
the position of the Beyrichia (?) clavigera shale and the base 
of Pamelia formation. This is the type locality for Bey- 
richia (?) clavigera and its variety clavifracta. 
Along the ditch on the right hand side of the road 
from this point to the next corner, there are excellent 
exposures of the lower dark limestone of the Pamelia. 
This limestone is here very fossiliferous, some of the layers 
being composed almost entirely of ostracods. At the next 
corner north, slabs of limestone with silicified fossils may 
be found in the fields, and near the top of the hill beyond, 
a quarry at the right shows the upper beds of the Pamelia. 
Just beyond this quarry, along the north-line fence 
of the same field in which the quarry is situated, there is 
an outcrop of the beds at the base of the Lowville. One 
of these beds contains an abundance of Beairicea, and 
another, better shown on the other side of the road, is 
full of specimens of Cyrtodonta huronensis. Beyond the 
next corner north, the Black River follows the Lowville, 
but it is hardly worth while visiting, as there are no unusual 
fossils in it.
