About This Book

The paper examines east-central Colorado populations of the pocket gopher Thomomys talpoides, determines they constitute a previously unrecognized subspecies, and names it Thomomys talpoides retrorsus. A type specimen from Flagler is designated, and a range along the western end of the Arkansas Divide is given. Diagnostic features include medium size, grayish-brown upperparts, a small skull with moderately inflated tympanic bullae, narrow U-shaped interpterygoid space, and posteriorly projecting premaxillary tongues. The author compares the new subspecies with several neighboring subspecies by color, skull dimensions, and temporal ridge form, provides measurements, lists examined specimens, and notes institutional acknowledgments.
