which underlies the Lowville. Although abundant, all the speci- 
mens were so badly preserved that they were at first thought 
to be “sea-weeds” or other indeterminable objects, until 
finally a single weathered specimen containing septa (Plate 
III, figure 2) was obtained. Being then unaware of Ulrich’s 
finds in Pennsylvania, the writer believed he had been the first 
to extend the geological range of these Beatricea - like forms, but 
soon came upon Ulrich’s list in Stose’s paper. Further in- 
vestigation revealed the presence of these fossils both in and 
below the Lowville at Mechanicsville, on the Ontario side of 
the river near Ottawa. These occurrences, listed as “ Beatricea 
sp.” were noted in a paper in the Ottawa Naturalist for February,

In June, 1911, the writer had an opportunity of visiting 
northern New York, and there, at the top of the Upper Pamelia 
and just below the Lowville, found the layer containing the same 
organisms at a number of places south of Clayton, About the 
same time, Mr. W. A. Johnston, of the Geological Survey, to 
whom I had shown my specimens, sent in from the field specimens 
much better than any I had found. They were obtained, as 
usual, from strata just below those containing Tetr odium cel - 
lulosum and Bathyurus extans, and the locality is near a wood 
road along the northern fence of lot 25, concession VI, of the town 
of Carden, east of Lake Simcoe, Ontario, about 150 miles west of 
the localities near Ottawa. This locality was visited again 
later in the year by Mr. Johnston and the writer, in 1912 by 
Mr, E. J. Whittaker, and a second time by the writer in 1913, 
so that a considerable amount of material has been accumulated. 
A list of the fossils from this locality so far determined was pub- 
lished by Mr. Johnston in the Summary Report of the Director 
of the Geological Survey of Canada for 1911 (1912), page 255. 
The most striking fossils are a remarkable Tetr odium (T. 
halysitoides Raymond), Onchometopus simplex Raymond and 
Narraway, and Bathyurus johnstoni Raymond. On the bads 
of these species, which have been found by the writer both at 
Ottawa and in northern New York at this same horizon just
