permit. The officers of the division co-operate freely with other depart- 
ments, especially the Departments of Agriculture, Interior, and Fisheries, 
on matters relating to wild life that are not adequately covered by any one 
department, and the accumulated notes and observations of many years 
often provide valuable and needed information. 
R. M. Anderson and P. A. Taverner have served as members of the 
Inter-departmental Advisory Board on Wild Life Protection. They 
attended the fiftieth anniversary meeting of the American Ornithologists' 
Union held in the American Museum of Natural History, New York City, 
November 14-16, 1933. Mr. Anderson also served as a member of the 
Northern Advisory Board, the Inter-departmental Reindeer Committee, 
and as honorary advisory zoologist for the Gatineau-Lievre-Nation division 
of the Province of Quebec Association for the Protection of Fish and Game. 
Field Work 
Considerable fresh material was collected near Ottawa for making 
habitat groups and a number of small mammals and birds were collected and 
mounted to fill out the school loan collections. Charles H. Young during 
the summer evenings collected insects, particularly Microlepidoptera, and 
added about 2,400 mounted specimens to the National Collection of Insects, 
including several forms that appear to be undescribed. Insect larvse, pupae, 
and cocoons were also collected and reared in order to have fresh, perfect 
material for display cases prepared by Mr. Young and Mr. Johnson. 
Office Work 
R. M. Anderson continued systematic work on the mammal collections 
of the museum, making special studies of several Canadian genera, 
especially pocket gophers (Thomomys) , red-backed mice (Clethrionomys ) , 
jumping mice ( Zapus ), hoary marmots of the Marmota caligata group, and 
red squirrels of the Sciurus hudsonicus group. 
The “ Check-list of Canadian Mammals ” is in card catalogue form, 
and w r ith some revision of ranges of certain species and subspecies is 
nearly in shape for publication. Some special work has been done on a 
descriptive and illustrated work on the “ Mammals of Canada,” to which 
all other revisionary and life history work on Canadian mammals is directly 
contributory. A bulletin on “ Animal Life and Life Zones of Southern 
British Columbia,” particularly the mammal life, is under way. 
Two papers were prepared by Mr. Anderson for the Division of Bio- 
logical Sciences, Fifth Pacific Congress, held at Victoria and Vancouver, 
British Columbia, June 1-14, 1933. One paper was entitled “ The Distribu- 
tion, Abundance, and Economic Importance of the Game and Fur-Bearing 
Mammals of Western North America ” (illustrated with revised map of 
life zones, and map of inter-mountain sub-faunas, and maps showing ranges 
of the species of fifteen groups of the more important game and fur-bearing 
mammals) , and one paper on “ Effect of the Introduction of Exotic Animal 
Forms.”
