Comments on the Taxonomy and Geographic Distribution of Some North American Rabbits

"Comments on the Taxonomy and Geographic Distribution of Some North American Rabbits" by E. Raymond Hall and Keith R. Kelson is a scientific publication written in the early 1950s. This work is focused on the taxonomy and geographic distribution of various species of North American rabbits, particularly within the genera Sylvilagus. As a scholarly article, it delves into specific classifications, regional differences, and morphological comparisons among species, contributing to the field of mammalogy. The authors meticulously examine different specimens of rabbits, particularly the Florida cottontail and Audubon cottontail, to clarify existing taxonomic confusions identified in earlier literature. They conduct comparative analyses of physical characteristics such as skull morphology to distinguish species and subspecies. Important geographical data are provided through maps, reinforcing the understanding of their habitat ranges. The research includes detailed descriptions of a variety of subspecies, such as Sylvilagus floridanus similis and Sylvilagus nuttallii grangeri, highlighting their differences and the potential for intergradation. Overall, this publication serves as a valuable reference for researchers working in mammalian taxonomy and conservation biology.
