Within the Great Basin, diversity of shrews (Soricidae) generally is low. We present information on distribution and ecology of shrews from the Ruby Mountains of northeastern Nevada, an area that is exceptional in supporting six species. The assemblage includes two habitat generalists and four species that are more ecologically specialized, three of which are poorly known. The high species richness of shrews in the Ruby Mountains reflects the large area, the ecological complexity, and the geographic overlap of several species.
