Forty-six large mammal skins (deer, bear, seal, fox, otter, beaver, 
badger, wolverine, and marten) were tanned by J, E. Perron for the reserve 
series of the Museum. A number of large, mounted mammal heads, skin 
rugs, and robes were fumigated and repaired for other Government branches. 
Considerable work is continually being done on skins that come to the 
Museum in a salted, soft, or unfinished state, and many skins prepared by 
inexperienced collectors have to be re-made. In all, 207 bird and small 
mammal skins were prepared, mostly by D. Blakely, for the study col- 
lections. Jos. Rochon, osteological preparator, cleaned and prepared a 
considerable amount of skeletal material of mammals and birds. 
C. E. Johnson, Artist of the Division of Biology, did work as follows: 
Colouring maps and lantern slides 52 
Colouring plates 9 
Colouring photo enlargements 10 
Coloured plates of Canadian mammals for illustrations 6 
Black and white drawings and lettered labels 14 
Plaster moulds 138 
Wax and celluloid accessory pieces for exhibition groups 
(mostly for Churchill bird groups) 2,815 
During the year, 282 mammals, birds, and amphibians were loaned to 
educational institutions for use in art and nature study. Of the mammals, 
the beaver was in greatest demand, with the muskrat a close second; of 
the birds, the chickadee and the robin were used most. fggj 
Considerable progress was made in the careful examination^ and 
identification of the accumulated mammal collections of the Museum, 
which now total 11,125 catalogued specimens, an increase of 7,163 speci- 
mens since the end of 1920. At the end of 1912, the mammal collection 
consisted of only 1,804 specimens. 
Several consignments of specimens were identified for various Cana- 
dian collectors and institutions, among which were the Royal Ontario 
Museum of Zoology, Toronto, the Provincial Museum, Victoria, B.C., and 
the Provincial Museum, Regina. The Museum specialists are always 
glad to examine such material from any part of the country, and in so 
doing not only aid collectors and owners of specimens, but also secure for 
the Museum authentic records of distribution of species in different parts 
of the country and, in occasional instances, establish new records of occur- 
rences. The first record for Canada of the least brown bat, or Lieb’s bat, 
Myolis subulatus leibii (Audubon and Bachman), collected by Eli Davis, 
near London, Ontario, May 9, 1929, and sent by him to the Museum for 
determination, resulted from the examination of a small lot of specimens. 
Officers of the division are prepared to identify and return any Canadian 
specimens of mammals, birds, reptiles, or amphibians, which are sent in a 
fair state of preservation and with sufficient data regarding locality and 
date of collecting. These may be addressed to the Director, National 
Museum of Canada, Ottawa. Where possible the Museum would be 
pleased to have duplicate specimens sent for deposit in the National col- 
lection. 
Mr. Arthur Gibson, Dominion Entomologist, and Honorary Curator 
of Insects in the Museum, has aided in the installation of systematic 
collections of typical specimens of several important oiders of insects and 
also a series of life history and habitat groups of insects of economic 
importance in Canada.
