ResumoThis contribution to the life history of the water shrew (Sorex palustiis navigator) is based upon a combirnation of field and laboratory studies. Published literature relating to the species is largely confined to taxonomic or distributional considerations. Only a few incidental observations concerning the habits of tnis small semi-aquatic insectivore are recorded. In the autumn of 1947 preliminary collection of specimens was begun. Subsequently it was indicated that sufficient material might be obtained to make a life history study possible. In February of 1948 a more detailed approach to the problem was started. This report is based upon material collected between September 1947 and September 1949. All specimens collected were obtained in western Montana, the majority being taken in Missoula County. This region is entirely within the range of the subspecies Sorex patuttris navigator as defined by Jackson (1928).
