WA THE HAMILTON ASSOCIATION. 
I previosly mentioned pointed to dead shells which had been 
washed shoreward. As in former years a large quantity of 
the two upper Clinton beds had to be removed from behind 
the upper reservoir, loosened by frost in spring and rain sub- 
sequently. This debris presented little of interest to ourselves, 
even when it contributed specimens which scientific brothers 
of St. Catharines so warmly appreciated in acknowledging 
their receipt. 
WINONA, LAKE SHORE. 
I already mentioned, only a short stay was made at Win- 
ona Park during the past summer, but the circumstances 
rendered it necessary to work a little more than usual along 
the lake shore, and to extend researches more easterly. Per- 
haps not many new things turned up, but rare specimens were 
found, and some (in better preservation) replaced poorer ones 
in our cases, or were forwarded to the Geological Survey 
Office, Ottawa, and elsewhere. 
The fossils now submitted for inspection have been selected 
especially for the purpose. It is by no means an easy matter 
(as was already stated) correctly to name a fossil solely from a 
woodcut and not the original. As regards the general appear- 
ance they may correspond, but you can notice minor omis- 
sions (which are of considerable importance however, ) in 
many of the figures given in Palzeontological works published 
even less than a quarter of a century ago. 
The small turbinated shell whose mouth is imperfectly 
outlined perhaps is a H/olopea. On comparing it with several 
described or figured by the late EH. Billings, and U. S. A. 
papers I failed to recognize any actual resemblance, neither 
can I recall Anticosti specimens to remind me of it now. 
Some fine Trenton slabs were obtained on the lake shore 
between Winona and Grimsby, east of a small creek 
whose inlet was closed by a sandbank, when visited ; it is some 
distance from the Park. You will find there a very extensive 
collection of shingle which doubtlessly contains many interest- 
ing Cambro-Silurian fossils: ‘The writer arrived rather late on
