A New Species of Pocket Gopher (Genus Pappogeomys) From Jalisco, México

"A New Species of Pocket Gopher (Genus Pappogeomys) From Jalisco, México" by Robert J. Russell is a scientific document announcing the discovery and definition of a distinct pocket gopher species in the Sierra del Tigre area of Jalisco, México. It adds to the science of mammals by describing the habitat and body features that set this species apart from its family. The book shares important findings from specimens mainly gathered by Joseph R. Alcorn, highlighting what makes the new species, called Pappogeomys alcorni, different from Pappogeomys bulleri, including specifics about their teeth and skulls. Russell points out how important this discovery is for learning about the range of mammal species in México and credits Alcorn for his work in this area.
