New records of Merriam’s Shrew (Sorex merriami) from western North Dakota

Abstract

Despite having a broad geographic distribution, Merriam’s Shrew (Sorex merriami Dobson 1890) is known from a relatively few, widely-scattered localities. In North Dakota, the species was known from only a single poorly-preserved specimen collected in 1913 near Medora. We recently collected two new specimens of Merriam’s Shrew from Billings and McKenzie counties in the western quarter of the state. These specimens confirm the presence of S. merriami in North Dakota and better define the northeastern edge of the species’ distribution.
