102 A FEW HINTS ON LOCAL FOSSIL COLLECTING 
of the band displays a sea-plant, which Professor Billings, 
a former Palzontologist of the Canadian Geological Survey, 
considered a tangled mass of ‘‘ a cord-like Alga,’ cone-like 
in appearance. 
Between this and ‘‘ the Iron band’’ above are several 
Brachiopods, Bryozoans, and a bead-like trail which was 
named by the late Principal of Montreal University, Sir W. 
Dawson. 
From a massive layer of ‘‘the Iron-band’’ (which I 
had to break up with a sledge), was obtained the fossil 
named by Hall and Clarke, ‘‘ Lingula Lingulata.’’ One of 
the beds hold many Valvas, coloured blue, of the New 
York State, Lingula L. Clintoni (Vanuxem). In the Upper 
Clinton band here (abounding with Species or varieties of 
Arthrophycus at Grimsby) nothing puts in an appearance 
but, fragments of Brachiopods. 
The best place about this locality for Clinton fossils is 
“ the bluff,’’ a little beyond the reservoir, which for several 
years has been closed to scientific research by the railway 
managers. It furnished me formerly with six Silurian 
star-fishes, one of them from the Iron band, all in fair or 
good preservation. I had previously discovered three 
others in the old quarries near the city, but portions of the 
fossils were injured or deficient. Stems of Crinoids are 
rarely found in our local Clinton rocks, and a single 
complete form was all I ever found, some thirty-five years 
ago. 
. Another interesting locality beside the bluff near the 
city was closed to scientific research some years ago by the 
Grand Trunk (Canadian) Railway—‘‘the Rock-cutting,”’ 
where the Niagara sponges were first discovered. Before 
entering this from the city side there was a limited exposure 
of Niagara shale, a portion of this had been spread on the 
surface of the road-bed, which proved to be very rich in the 
well-known Grimsby crinoids. ‘‘ Caryocrinus Ornatus,”’ 
and ‘‘ Stephanocrinus angulatus ’’—Altho’ not so well pre-
