discoveries in this locality both with regard to the general 
appearance and the position of the Cellules at least in some 
instances. 
The only shot during the past collecting season in the base 
of the Niagara limestone (immediately above the upper Clinton 
green band) revealed a very fine branching Fucoid of unusual 
dimensions and in good preservation. It appeared in a thin 
layer, below the Pentamerus bed which sometimes is separate 
but more frequently incorporated with it. The charge of 
powder fortunately split the flag along the line of bedding, and 
did not break it across. As may be supposed from its position, 
in the centre of a limestone the cylindrical stems have been 
flattened. The pressure to which it was subjected may have 
altogether changed its original appearance. I have reason to 
imagine a fragment of a fluted (grooved) Sea plant which 
members of the Geological Section often noticed as occurring 
on the surface of the Pentamerus limestone may have repre- 
sented a portion of such a Fucoid as the one below it. 
The Niagara’ chert beds or rather the glaciated 
layers either removed in “he zce-age or perhaps in some 
weathered out along or contiguous to the corporation 
drain during the past season displayed quite a number 
of fossils, but the two rarest sponges, now in the British 
Museum, were found in fields adjoining the escarpment, 
one, undescribed, west of the Glanford road and the other 
a little beyond the Reservoir. The latter was a tube-like form, 
aspecies of Aulocopina in good preservation. Mr. A. K.Walker 
knows the one in question. I have not seen any so perfect 
hitherto, and as it is rarely met with, and wedo not possess a 
specimen in the museum cases probably, I felt somewhat 
reluctant abont sending it away until on reflection I concluded, 
if new to science, it had a better chance of being figured and 
described in the old country than here. 
Independent of the two mentioned, several other sponges 
in good preservation were obtained and transmitted to London 
through the Parcel Post. I regret, however, we failde to geta 
duplicate of the very extraordinary one formerly in possession
