"A New Long-eared Myotis (Myotis evotis) From Northeastern Mexico" by Rollin H. Baker et al. is a scientific publication written in the mid-20th century. This concise text focuses on the taxonomy and morphological characteristics of a newly identified subspecies of bat found in northeastern Mexico, specifically detailing its differences from related species. The work is part of the University of Kansas Publications and contributes to the field of mammalogy. The book presents detailed findings on the newly named subspecies, Myotis evotis auriculus, highlighting its physical attributes such as size, coloration, and skull measurements, as well as its geographical distribution across areas of Coahuila, Nuevo León, and Tamaulipas. Baker and Staines outline methodologies for capturing specimens, analyses conducted to arrive at their classification, and comparisons to other Myotis species. The publication ultimately serves to enrich the scientific understanding of bat diversity in the region and provides vital information for further studies in mammalian biology and conservation efforts.
