JOURNAI, AND PROCEEDINGS. 33 
warded, which the Professor, no doubt, will be pleased to receive. 
The writer holds over others for future transmission, but many 
more were left behind ; not removed from Winona camp yet. 
On Victoria Day some members of the Geological Section and 
friends from Dundas proceeded on an excursion to Grimsby. One 
of the party, Mr. Schuler, was provided with a hand-rake, furnished 
with long close teeth, which was suggested as an improvement on a 
claw-like implement. I used these on the loose shale formerly ; it 
proved very useful for the purpose of raking in the Niagara shale 
Crinoids. He displayed no less than six specimens of ‘“Caryo- 
crinus ornatus,” and two heads of ‘‘ Rhodocrinus,” independent of 
Bryozoons, etc , when he produced his collection for our inspection. 
The most perfect specimen of a Crinoid, however, found on this 
occasion, was one secured by a young fellow from Dundas. Mr. 
Freeborne of the same place was successful in obtaining from the 
upper Clinton there a well defined plant of this upper Silurian age, 
and to which I may call your special attention. Under the name 
**Fucoides Harlani,” Conrad described (and figured probably) a 
sea plant from the Medina sandstones in the annual report, New 
York State Survey, 1838. This name was changed subsequently to 
‘‘Arthrophycus Harlani” by the late Dr. James Hall, who men- 
tioned it as occurring at this horizon. I have not seen the plant 
from the New York Medina beds, but Mr. Schuler informs me the 
ones he observed in the Rochester Museum resembled the large 
“‘ Arthrophycus Harlani” found in the massive upper Clinton sand- 
stone bed at Grimsby. A mistaken idea was entertained, even by 
members of this section, that the layers in which the Fucoid occurs 
at place above mentioned represented Medina—not the Clinton 
series—and that the latter was altogether absent there. It was 
difficuit to imagine that our Hamilton Iron-band, with its soft red 
shales, should be there represented by the mottled sandstone used 
in building houses in that neighborhood. Closer observation has 
since convinced many that the writer was not mistaken in correcting 
a very erroneous idea. The plants discovered at Grimsby require 
further. investigation. They are found in three or more distinct 
layers, varying considerably in size; all are in good preservation 
there, and it hardly seems possible to’ look upon the smaller 
ones as young representatives of the family group. I think pale-
