Evidence of the extinct ground sloth in Iowa is very meager, but additional remains are being brought forth yearly. At the present time the knowledge of its presence is limited almost entirely to the counties bordering the Missouri River; the one exception is Dubuque County, in the middle-eastern portion of the state. Three specimens have been added to the collection in the past year. A tooth of the Megalonyx from Dixon Creek, Fremont County, collected by George Day, and a tooth and claw bone from Chabaneau Creek, Mills County, collected by the writer. The tooth from Chabaneau is exceptionally long and well preserved.
