THE HAMILTON ASSOCIATION. 17 
NOTES ON SPECIMENS FROM SEASON’S 
COLLECTION, 
Read before the Geological Section of the Hamilton Scientific 
Mesaeianion December 26, 1002. 
“The Webber Quarry,” at least that portion handed over 
to the corporation, produced of late some few well preserved 
Graptolites, and several others so weathered as to render them 
too imperfect to determine. If we include the ones from that 
portion. the proprietor retained, and blue building beds quar- 
ried by both, about six or eight new to this continent were dis- 
covered probably. The writer has not seen any found in the 
European Upper Silurians by Barrande, etc., figured or de- 
scribed. ; 
A new Hamilton Sponge, “Aulocopina Walkeri”’ (Head) 
has been added. Two other Sponges, N. S., probably were 
obtained (not discovered). A very fine slab from the Clinton 
iron band, with many specimens of Lingula Clintoni (Conrad). 
was placed in the Museum. The Clinton Coral, Cyathophyl- 
lum Articulatum, referred to by Prof. Lambe, has not been 
found so low as these beds hitherto. 
“Platyceras Angulatum’ may be added to Niagara 
Shales, Grimsby. The Discina (Trenton Drift, Winona) 
seems a new species, as is the Lingula from the same place per- 
haps. The Drift fossils found by Mr. Bartlett, “ Cyclonema 
Bivex,” “Glossina Trentonensis,” etc., may also be added to 
our list of Hamilton Drift fossils.
