450 UPPER CAMBRIAN AGE OF DICTYONEMA SLATES.—AMI. 
loaned to me for study and reference by Prof. L. W. Bailey of 
the University of New Brunswick, it was readily seen that the 
Benton specimens were also Upper Vambrian in age. 
In order to ascertain definitely whether D. Websteri, 
Dawson, from New Canaan, was identical with D. flabelliforme, 
the type specimens of the former, which formed part of the 
Dawson collections in the Peter Redpath Museum of MeGill 
University, were sought, and kindly loaned to the writer by Prof. 
F. D, Adams. These are preserved on two slabs of more or less 
hardened sericeous or glossy red shale or slate, and scattered 
over the surface of the slates in a rather fragmentary state of 
preservation, except in one specimen, from which the illustration 
on p. 563, (fig. 196,) was very probably made when the “ Acadian 
Geology ” was prepared. 
From a careful study of all the material in hand, the writer 
is satisfied that the upper beds of the Cambrian System are thus 
represented in that portion of Nova Scotia where the Dict- 
yonema flubelliforme beds of Kentville, New Canaan, and the 
Gaspereau Valley, (south side,) occur. 
We thus find that the zone or horizon of Dictyonema flabelli- 
forme, Eichwald, occurs at the following localities in Canada, 
which may consequently be referred to the Upper or Neo- 
Cambrian :— 
(1.) Matane, Quebec, South Shore of St. Lawrence River. 
(2.) Cape Rosier, Gaspé, Que., near Lighthouse. 
(3.) Barachvis, Cape Breton, Nova Scotia. 
(4.) Navy Island, near St. John, New Brunswick. 
(5.) Shales near Benton, above Fredericton, York County, 
New Brunswick. 
(6.) New Canaan, Annapolis County, Nova Scotia. 
(7.) Kentville, Annapolis County, Nova Scotia. 
(8) Angus Brook, Gaspereau Valley, Kings County, Nova 
Scotia. 
Associated with Dictyonema flabelliforme at Angus Brook, 
are found obscure remains of a Bryograptus, allied to B. Ajerulft 
from the Upper Cambrian of Scandinavia.
