There has recently been exhibited in the Gallery of Fossil Mammals at the Natural History Museum a restored skeleton of Stenomylus hitchcooki, Loomis, a ‘gazelle-camel’ from the Lower Miocene of Nebraska. This specimen (M 10969), which has been mounted in relief by Mr. L. E. Parsons, jun., includes portions of the skeletons of two individuals, but much of the dorsal region of the vertebral column and the ribs have been restored in plaster. The remains are from the Lower Harrison Beds (Lower Miocene) near A gate Springs, Co. Nebraska, where upwards of forty skeletons were collected in a small area. Many were complete and lay in such a position that they are believed to be the remains of a herd overtaken by floods and drowned.
