The comparison was made for the purpose of seeing how far the 
muscular system of one genus corresponds to that of the other. The 
ventral value of Acrothyra was compared with the tube of Hyolithes, 
and the dorsal valve of the former genus with the operculum of the 
latter. The Hyolithes described is a slender species from the base of 
the Paradoxides beds at St. John. 
13.—* A backward step in Paleobotany.” By G. F. Matthew, 
LL.D. 
This is a review of the attempt made to claim the plant beds of the 
Little River Group and their flora, and so the whole terrane, as Carboni- 
ferous. This claim is made on paleobotanical grounds by Messrs. D. 
White, R. Kidston and H. M. Ami. 
The article recites the stratigraphical and physical objections to 
this view, and in this connection two sections near St. John are given, 
showing the relation of this terrane to the Lower Carboniferous. The 
fauna of the plant beds is reviewed and it is suggested that even from 
this point of view there is not sufficient evidence to overthrow the result 
arrived at by those who had previously studied the flora and the strati- 
graphy. 
14.—“The Avi-fauna of the Province of Quebec.” By Sir James 
Le Moine. 
15.—*The Anatomy and Physiology of the Brain of the Bird, being 
a continuation of a former communication.” By Wesley Mills, M.A., 
M.D. 
The Committee appointed by Section IV. last year to prepare 
records of the various papers and publications on Canadian Geology, 
Paleontology, Botany, General Zoology, exclusive of Entomology, and 
Entomology, in the terms of the recommendation of the Society re- 
ported on the MSS. of the Bibliographies on Geology, Paleontology, 
and General Zoology were submitted for publication as were also those 
on Botany and Entomology. 
The Section has seen fit to re-appoint the same Committee for the 
ensuing year :— 
Geology and Palæontology.—Dr. H. M. Ami. 
General Zoology—Dr. J. F. Whiteaves. 
Botany—Dr. A. H. MacKay. 
Entomology—Rev. Dr. Bethune. 
As noted above, the Memorial, which the Society requested to be 
prepared for publication, of the deceased first President of this Society, 
Sir William Dawson, was entrusted to the pen of his successor in the 
Logan Chair of Geology at McGill University, in the person of Dr. 
F. D. Adams, and this Memorial forms part of the papers submitted
