This work focuses on the various species of lagomorphs, including rabbits, hares, and pikas native to North America. It aims to consolidate existing knowledge on the taxonomy and geographic distribution of these mammals while providing critical insights into their biology and ecological significance. The opening of the book introduces the topic by highlighting the significant role that rabbits and hares play as small game in North America, along with their importance in scientific research related to public health. Hall notes the increasing inquiries from researchers regarding the taxonomy and relations of these species. He outlines the aims of the synopsis to centralize updated taxonomic arrangements and geographic data, complemented by visual aids like maps and illustrations. Additionally, Hall addresses the challenges in identifying species based on morphological features, emphasizing the relevance of geographic factors in understanding these animals' diversity.
