A taxonomic study was made of mammals occuring in Grand Teton National Park by means of trapping or observation. Measurements were made and study skins were prepared of all specimens obtained. The small animals were trapped by means of Museum Special snaptraps, Victor mouse traps and snap type rat traps of various kinds. A few specimens were contributed by Dr. William Calder, and these had been taken in Sherman or Havahart live traps.
