lamellabranchs, etc. When pointing out to a new member of 
the section, who lately joined our Association, places where 
fossils would be likely to reward research, my companion, Mr. 
Schuler, had the good fortune to secure a good specimen of 
‘* Uncimulus Striklandi”’ (Sowerby). Its occurrence in Ontario 
has not been noted by Schuchert or Nicholson, I think. Years 
ago the writer put in possession of the Dominion Geological 
Survey one which he supposed to be identical with Rhyvnachonella 
Tennesseensis (Roemer). Theupper portion of the Barton series 
(lime ridge limestones in rear of the Mountain View Hotel) 
presented nothing new, and the Stromatopora corals are diffi- 
cult to extract from the upper layer. The middle portion or 
water lime beds at or above the Albion Mills was visited only 
a few times during the past summer when no species unknown 
were obtainable. The writer believes the rock cutting on the 
T. H. & B. Railway, beyond Stoney Creek, has not yet been 
examined by our local geologists. The Niagara shale at 
Grimsby, where many Crinoids, Bryozoons and some Star 
Fishes occur. The upper Clintons there—rich in plant remains— 
the lake shore lower Silurian shingle and drift limestones 
between Winona and Grimsby are well calculated to attract the 
collector’s attention. 
A CYRTOCERAS FROM THE NIAGARA CHERT, HAMILTON. 
The specimen recently obtained bears rather a close re- 
semblance to a gigantic one found some years ago in the Barton 
bed above the Albion Mills. undescribed probably. It does not 
appear to agree with any fossil described or figured among 
the Niagaras of Hall or Nicholson. Although unusually large 
for a chert fossil, it may be only a dwarfed sample of the Barton 
Cyrtoceras referred to.
