Notiosorex is a genus of small, generally gray shrews with short tails and relatively large ears that are clearly visible. Members of this genus are found in Mexico and the United States. Three species occur in the United States; Cockrum's Gray Shrew (Notiosorex cockrumi), Desert Gray Shrew (Notiosorex crawfordi), and Ticul's Gray Shrew (Notiosorex tataticuli). As with all members of the subfamily Soricinae, Notiosorex have red-tipped teeth. The enamel of the tips of their teeth is reddish due to iron pigment, which serves to harden the enamel.
