ABSTRACT: Three subspecies of the southeastern shrew (Sorex longirostris) currently are recognized: S. l. eionis from Citrus Co., Florida; S. l. fisheri from the Dismal Swamp in eastern Virginia and North Carolina; and S. l. longirostris from the remainder of the southeastern United States. Based on geographic variation of seven skull, dental, and external measurements, differences among the three subspecies were confirmed. S. l. eionis was distributed throughout peninsular Florida, but S. l. fisheri had a restricted distribution. Hence, land development might represent a threat to the survival of this population. A few specimens hint at a larger range for this subspecies, but more data are needed to explore this possibility
