66 THE HAMILTON ASSOCIATION. 
of our President, Mr. A. EK. Walker, representing three or 
more distinct Azlocopinas, rising from a common platform, the 
platform itself evidently of the same nature as the sponges 
above, so the connection could not be doubted. The writer felt 
inclined to look on it as a Bryozoon until it was more closely 
investigated. In several instances only a single specimen of a 
sponge has been found, Aa/lastronta (Head) for example, - 
another in the Museum, Niagara case, appears a new Genera 
altogether, but no duplicate has been discovered; the field in 
which the latter was found has not been ploughed up for 
some years; it may possibly reward research under more, 
favorable circumstances. “The old reliable locality to which I 
have frequently directed your attention adjoining the corpor- 
ation drain presented a few rare fossils to Messrs. Bartlett and 
Schuler but nothing new to self or others, as far as I know. 
Indeed since the crop this field contained was gathered in, it 
became almost completely covered with clover, grass and weeds 
which concealed the chert-flakes. However, on turning over 
a few which were exposed on a comparatively bare patch, 
some very fine specimens of Dr. James Hall’s Cladopore were 
revealed, in the field opposite (other side drain) two fine heads 
of ‘Trilobites were discovered, one may be the shield of Lzchas 
Boltont Var. occidentalis, Hall, who figures the tail part but not 
the head, which probably has not been previously found, he 
describes Lichas breviceps from two imperfect specimens, it will 
hardly come under that head. Another rare fossil which turned 
up there was a Cornulites, undescribed so far as I can see, the 
tube is plain, straight but slightly curved occasionally which 
leads one io imagine it may have been flexible. The most 
common form of Cornulites in the glaciated chert (upper beds) 
is C.bellasiriata, Hall. Mr. Schulerof this section obtained a fair 
specimen lately when we were collecting in the Drain field. A 
prevailing impression among the younger fossil collectors 
here seems to be that the older hands already secured every- 
thing worth taking in the shape of organic remains, such as 
sponges, sections, etc., from fields near the city. I can assure 
you in refutation of this, it is not borne out by the writer’s
