1899] REPORT OF THE GEOLOGICAL BRANCH. 22 1 



terville of limestones and shales alternating with each other, rest 

 perfectly conformably upon the uppermost measures of the Trenton 

 formation. The writer desires to emphasize this statement in view 

 of the oft-repeated assertion that throughout eastern Ontario and 

 Quebec the Utica everywhere rests unconformably upon the Trenton 

 formation. (See Trans. Roy. Soc. of Can., Vol. I, p 258. 1883. 

 Paper by T. Stery Hunt.) 



Amonofst the interestin<>: collections made about Ottawa by 

 local collectors during the past year may be mentioned one by 

 Mr. W. H. Roger, of ]>illings's Bridge. Amongst the species 

 recorded in the Roger collection from the Utica of Billings's 

 Bridge there are two forms which prove to be hitherto unrecorded, 

 whilst the remaining species, eminently characteristic of the Utica, 

 are sufficiently numerous to enable one to state the precise horizon 

 of the strata from which they were obtained. One of these is a 

 gastropod — a Lophospira which bears a considerable resemblance 

 to L. conoidea, Ulrich, but is more depressed and has a much 

 larger apical angle, &c. I venture to suggest the name Loplio- 

 spira Billirigsensis, for this species awaiting an opportunity of 

 illustrating it and describing the same in a more complete form. 



Nonnal School Collection of Local Fossils. — In order to stimu- 

 late local research in Palaeontology and in a small measure to 

 assist the educational world around us, the writer has undertaken 

 to arrange and classify a number of the more typical and easily 

 recognised fossils from the different geological horizons in the 

 Ottawa Valley. These were presented to the Principal of the 

 Normal School, and now occupy a portion of the flat show cases of 

 the physics laboratory. The collection consists of about 150 

 specimens, which serve to illustrate nearly all the Palaeozoic 

 formations comprised in the Ottawa Valley. They include the 

 following formations : 



VIII. Niagara. 



VII. Lorraine. 



VI. Utica. 



V. Trenton. 



IV. Bird's-eye and Black River. 



III. Chazy.
