REPORT OF THE ZOOLOGICAL BRANCH, 1904. 
The leaders ia Zoology have again to report that, while much 
useful work in this branch of biological science has been done by 
various members of the Club, there is little of such novelty or im- 
portance to record as to justify detailed notice in this annual 
report. The fact that Ornithology, Entomology and Conchology 
are dealt with in separate reports, precluding reference to them in 
the Zoological report, seriously confines the field, so far as im- 
portant seasonal observations go, as the mammals, fishes, etc., 
offer themselves less readily to continuous study by naturalists 
resident in a city. Still the field is a most inviting and promising — 
one, and, as pointed out in previous reports, there are many lines 
of work which are open to those desirous of adding to our stock 
of zoological knowledge. 
The Hudson’s Bay expedition which returned last fall, atten 
fifteen months’ exploration in the Arctic waters of Canada, made 
some interesting contributions to Dominion zoology. 
In the Report of the Department of Marine and Fisheries just 
issued the following resumé is given of the preliminary account 
furnished by Mr. Andrew Halkett, naturalist on board the SS. 
‘« Neptune.” 
Mammals.—The mammals observed were limited to four 
orders, the Carnivora, the Rodentia, the Ruminantia, and the

Bear ( Thalartos maritimus), the Barren-ground Wolf ( Canis

Fox, ( Vulpes lagopus), the Polar Hare ( Lepus arcticus ), certain.

for mounting, were preserved, with a series of seo bones,
