70 THE HAMILTON ASSOCIATION. 
staff of the Toronto University—one of the old country’s 
leading palezeontologists—has also taken very great interest in 
this class of fossils and is looked upon as one of the best 
authorities regarding the sponges generally. Many years ago 
he received specimens from the Hamilton beds, and we may 
rest assured he would not lose time in investigating the many 
species which were lately forwarded to the British Museum 
through Professor T. Rupert Jones. 
WINONA AND GRIMSBY. 
A shorter stay than usual was made last summer at 
Winona Park, and only three visits during that time were paid 
to the Grimsby quarries. The latter presented an unusual 
number of Upper Clinton slabs containing the well preserved 
Fucoid of the late Dr. James Hall, Arthrophycus Harlant, and 
the smaller variety of tke plant found on the surface of a thin 
sandstone layer. In the previous summer the debris of the 
old quarry workings furnished most of slabs containing the 
fossil, but this spring large masses of the Upper Clintons had 
fallen down from overhead, and from this alone not less than 
seven fine slabs were removed when first visited. Later on in 
company with Mr. Schuler a fourth visit was paid to the 
locality and we returned to the railway station with a very 
extensive collection, in fact with as much as we could well 
convey tothe train. The chief portion of my time was occupied 
in rendering a splendid slab containing the large Avthrophycus 
Harlani sufficiently portable to enable its removal to be 
effected from the quarry. My companion had secured a varied 
assortment, many rare Bryozoons, etc., but few I think 
unknown. 
Messrs. Schuler and Bartlett subsequently visited Grimsby 
and informed me they were perfectly satisfied with the speci- 
mens secured on the occasion. ‘The former discovered the 
arms of a crinoid Eucalyptocrinus (1 was unable to find the 
body or any plates on the shale slab) and the well known 
Niagara Caryocrinus ornatus. Except when pointing out 
where fossils were most frequently found, for my part I con-
