A short time ago a partly broken skull of the Western Fox Squirrel, (Sciurus niger rufiventer (Geoffroy), bearing a curiously formed upper incisor was brought to me for examination by Mr. W. F. Kubichek, now of the Children's Museum, Brooklyn, New York. The animal was evidently an adult and was killed near Homestead, Iowa, November, 1917. The lower mandible as well as the posterior portion of the brain case is missing.
