A New Chipmunk (Genus Eutamias) from the Black Hills
"A New Chipmunk (Genus Eutamias) from the Black Hills" by John A. White is a scientific publication written in the early 1950s. This work focuses on the taxonomy and description of a new subspecies of chipmunk, revealing insights into the biodiversity of small mammals in specific regions of the United States, particularly the Black Hills and surrounding areas. In this publication, White presents a detailed study of the chipmunks found in northeastern Wyoming and South Dakota, which had previously been misidentified. He formally names and describes a new subspecies named "Eutamias minimus silvaticus", providing specific measurements, diagnostic features, and comparisons with related subspecies. The paper includes meticulous data on the physical characteristics of this chipmunk, emphasizing differences in coloration, size, and skull structure when compared to similar species. Additionally, it discusses the geographical range of the subspecies, underscoring the importance of this research in understanding mammalian diversity in North American ecosystems.

Taxonomy of the Chipmunks, Eutamias quadrivittatus and Eutamias umbrinus
"Taxonomy of the Chipmunks, Eutamias quadrivittatus and Eutamias umbrinus" by John A. White is a scientific publication written in the early to mid-20th century. This academic work focuses on the classification of two chipmunk species, discussing their anatomical and color differences, and emphasizing the need for precise measurement techniques in taxonomy. It provides a historical overview of the research surrounding these species and contributes to our understanding of rodent differentiation based on morphological features. The book delves into the taxonomy of the chipmunks Eutamias quadrivittatus and Eutamias umbrinus, detailing their distinct morphological traits, particularly skull and coloration characteristics that distinguish them from each other and other related species. White presents a comprehensive examination of various subspecies, providing diagnoses, descriptions, and comparisons that reveal their ecological distribution across North America. The study is methodologically rigorous, utilizing statistical measures and specimens across multiple regions, and it highlights the significance of geographical and ecological factors in the evolution and distribution of these chipmunks.

Genera and Subgenera of Chipmunks
"Genera and Subgenera of Chipmunks" by John A. White is a scientific publication written in the early 1950s. The book explores the taxonomy and structural classification of chipmunks, specifically focusing on different genera and subgenera within the Sciuridae family. It addresses longstanding controversies regarding the classification of these small rodents, providing detailed morphological analyses and comparisons. In this publication, White scrutinizes the similarities and differences among chipmunks, particularly between the subgenera Eutamias and Neotamias, as well as the genus Tamias. Through extensive examination of anatomical structures such as the malleus and baculum, he argues for a reevaluation of the relationships and classifications within these groups. The book presents a thorough analysis based on the examination of numerous specimens and historical taxonomic literature, culminating in a set of conclusions that propose clearer distinctions among the chipmunk subgenera and genera based on structural and taxonomic evidence.

The Baculum in the Chipmunks of Western North America
"The Baculum in the Chipmunks of Western North America" by John A. White is a scientific publication written in the early 1950s. The book focuses on the baculum, the bony structure found in the male reproductive anatomy of chipmunks from the subgenus "Neotamias". It explores the variations in the baculum's morphology across different species of chipmunks in Western North America and assesses its utility for taxonomic classification. In this publication, White meticulously details the anatomical differences in the baculum among various species of the "Eutamias" genus. He provides descriptive accounts and scientific illustrations for each species, including morphological measurements and comparisons. The paper also discusses the implications of baculum structure in relation to existing classifications based on other physical characteristics like skull and skin features. Ultimately, the research underscores the baculum as a crucial taxonomic tool, providing insights into the evolutionary relationships and ecological adaptations of these small mammals.

Geographic Distribution and Taxonomy of the Chipmunks of Wyoming
"Geographic Distribution and Taxonomy of the Chipmunks of Wyoming" by John A. White is a scientific publication written in the early 1950s. This work focuses on the classification and distribution of various chipmunk species found in Wyoming, analyzing their interrelationships and habitat variations. The book aims to provide a detailed account of these small mammals, offering insights into their taxonomy and geographic range. In this detailed study, White examines the chipmunks belonging to the genus Eutamias in Wyoming, highlighting specific species and subspecies, such as Eutamias minimus and Eutamias amoenus. The author outlines the methodology used in collecting, measuring, and analyzing chipmunk specimens, presenting statistical data and population distributions across different habitats. The book includes descriptions of physical characteristics, differences in size, and color variations among the subspecies. It culminates in discussions on how glacial events influenced the current distribution of these animals and proposes hypotheses regarding their evolutionary adaptations in relation to the changing environment.
