Taxonomic Status of Some Mice of The Peromyscus boylii Group in Eastern Mexico, With Description of a New Subspecies

"Taxonomic Status of Some Mice of The Peromyscus boylii Group in Eastern Mexico, With Description of a New Subspecies" by Ticul Alvarez is a scientific publication produced in the early 20th century, specifically in the early 1960s. This work primarily focuses on the taxonomic classification of certain mouse species within the Peromyscus boylii group in Eastern Mexico, analyzing their differences, subspecies, and geographical distribution. In the publication, Alvarez reviews previous classifications and provides new insights into the differentiation between various species and subspecies of the Peromyscus boylii group, notably distinguishing traits among species like Peromyscus aztecus and Peromyscus boylii levipes. The author examines specimens collected from specific regions such as Veracruz, Puebla, and Nuevo León, offering detailed descriptions of new subspecies, particularly the small-sized Peromyscus b. ambiguus. This comprehensive analysis helps clarify the taxonomic status of these mice, emphasizing their unique morphological characteristics and contributing to the understanding of ecological diversity in this region of Mexico.
