Mammals Taken Along the Alaska Highway
ROLLIN H. BAKER
INTRODUCTION
Mammals from along the Alaska Highway were obtained for the University of Kansas Museum of Natural History in the summers of 1947 and 1948 by Mr. J. R. Alcorn, field representative of the Museum. He and his family visited Alberta, British Columbia, the Yukon Territory and Alaska in an automobile and trailer from June 9, 1947, to September 6, 1947, and again from June 8, 1948, to August 24, 1948. In 1947, considerable time was spent by Alcorn in Alaska; trips were made on the Steese Highway to Circle and on the Glenn Highway to Anchorage. In 1948, most of the collecting was done in British Columbia and in the Yukon Territory but a side trip was taken to Haines, Alaska. The collecting stations are shown in figure 1. Alcorn's 1,252 specimens include several large series from areas where few or no mammals had been taken previously. Time spent at each collecting station was of short duration and although 56 species and subspecies of mammals are represented in the collections, it is recognized that not all of the kinds of mammals at any one locality were taken.
For the loan of comparative mammalian material, grateful acknowledgment is made to officials of the following institutions: California Academy of Sciences; Biological Surveys collection of the U. S. National Museum; Provincial Museum, Victoria, B. C.; National Museum of Canada. The promptness of officials of the game commissions of the provinces and territories concerned, in providing permits for collecting also is acknowledged. A part of the funds for field work was made available by a grant from the Kansas University Endowment Association. Elevations above sea level are given in feet. Capitalized color terms refer to those in Ridgway, Color Standards and Color Nomenclature, Washington, D. C., 1912.

ACCOUNTS OF SPECIES
Sorex cinereus cinereus Kerr
Cinereous Shrew
Alcorn found the cinereous shrew at most of his trapping stations. It was captured in mouse traps baited with "chewed" rolled oats; one was taken in a trap baited with a grasshopper. Rand and Alcorn each found this shrew to be one of the commoner mammals along the Alaska Highway, but Alcorn did not find it to be so abundant as some of the rodents in areas in which he trapped. The cinereous shrew was taken principally in moist woodlands, grassy areas, and adjacent to water. One female taken on July 18 was lactating.

Sorex cinereus hollisteri Jackson
Cinereous Shrew
Sorex obscurus obscurus Merriam
Dusky Shrew
Alcorn, like Rand , found the dusky shrew to be less common than the cinereous shrew; both were taken in the same trap lines. The dusky shrew was taken at a higher altitude than the cinereous shrew.
