Maritime Shrew, Arctic Shrew, range extension


We report the first record for the Arctic Shrew (Sorex arcticus) in the state of Montana, USA. We also report range extensions for the closely related Maritime Shrew (Sorex maritimensis) in New Brunswick and Nova Scotia, Canada. These collections augment our limited knowledge of the ranges and habitat associations of these rarely collected shrews, and highlight the need for a careful assessment of the status of S. maritimensis in Canada.
