STUDIES ON THE HELMINTH FAUNA OF ALASKA. VII-ON SOME HELMINTHS FROM ARCTIC MARMOTS WITH THE DESCRIPTION OF CATENOTAENIA REGGIAE

Among Alaskan mammals examined for helminthic parasites during 1950 was a series of marmots, Marmota caligata broweri Hall and Gilmore, 1934, from the Brooks Range, Arctic Alaska. The animals were collected a few miles south of Tolugak Lake (lat. 680 24 ' N., long. 1510 26 ' W.), and from the vicinity of Kanayut Lake, about 15 miles northeast of Tolugak Lake. This distinctive marmot has been hitherto represented in collections only by the three specimens comprising the type material. In addition to greatly extending the known range of this form, the collection of these specimens also contributes the first information on Brooks Range marmots (Rausch, 1950). Three species of helminths occurred frequently in the twenty-odd animal
