general species AZ. tntumescens, but with the modern methods of 
ontogenetic study of the cephalopods, which have been used in a most 
satisfactory way in conducting this investigation, specific lines are 
drawn with far greater precision. The ontogenetic stages of most of 
the species are carefully described and fully illustrated by many figures 
in the text, so that the paper is valuable to the biologist as well as to 
the geologist.

IX, 1896. Dr. G. M. Dawson, Director. 
During the year work was done in British Columbia, Alberta, 
Ontario, Quebec, Nova Scotia, Labrador, and the region west of Hud- 
son Bay. 
In British Columbia Messrs. McConnel and McEvoy gave their 
attention to the mining region around Nelson, Trail and Rossland. 
Some important facts are noted regarding the occurrence of ores. A 
boring in the Cretaceous formation at Athabasca Landing, Alberta, was 
carried to a depth of 1770 feet in the hope of reaching the petroleum- 
bearing “tar-sands”’ which form part of the lowest member of that 
formation to the northeast. The boring had to be abandoned, but 
other attempts will be made. 
The report of Mr. J. B. Tyrrell on his work in the unexplored 
region west of Hudson Bay is one of special interest. He gives an 
historical sketch of earlier explorations of Hudson Bay and adjacent 
lands, many of which were connected with the search for a “ North- 
west Passage.”’ The formations observed include the Recent, Pleisto- 
cene, Silurian, Cambro-Silurian, Cambrian, Huronian and Laurentian, 
of which the last is by far the most extensive. Pleistocene sea beaches 
and terraces are found at heights of 100 to 600 feet above sea level. 
In several places series of four to seven terraces mark shore lines of 
later glacial and postglacial times. The glacial geology of the 
region is accorded about twenty pages of the report. Several centers 
of glacial outflow are noted, about 140 strial directions recorded and 
many eskers, drumlins, moraines and extra-glacial lakes are described. 
A map accompanies the report. 
Dr. Bell’s report on his work in Ontario consists of a correlation 
of reports of work done at various times on the area of the French
