Abstract

"Three upper molars collected from an early Pleistocene site in the Soan Formation of the Upper Siwaliks outcropping in the Pabbi Hills of northern Pakistan are described as a new species of Hadromys. That genus was known only by the living H. humei, which is found in northeastern India. Compositions of the murine faunas of northeastern India, northern Pakistan, and Pleistocene Pakistan are compared. Because the new Hadromys is associated with fossil species of Golunda, another Indian native, and because that genus has also been identified in Pliocene sediments of Ethiopia, morphologies of specimens in samples of Recent and fossil Golunda are contrasted. Golunda remains an Indian region endemic; the Ethiopian species is not a member of that genus and is known only from northeastern Africa. Biogeographical relationships between the Indian subcontinent and northeastern Africa as indicated by Recent and fossil murine faunas are discussed"--P. [1].
