We have no record of this species in Harding County other than Visher's (1914:91) report that an individual was "recently trapped along the Little Missouri River." ~Felis concolor hippolestes~ Merriam, 1897 Mountain Lion This large cat likely occurred throughout northwestern South Dakota prior to settlement by white man. No specimens are available from Harding County, but Visher (1914:91) reported that an individual "visited the East Short Pines in the winter of 1910-11." It is doubtful that _Felis concolor_ occurs in the area today, except possibly as an occasional transient. ~Lynx rufus pallescens~ Merriam, 1899 Bobcat _Specimens examined_ (3).--12 mi. N, 9 mi. W Buffalo, 1; 11 mi. N, 7 mi. W Buffalo, 1; 9 mi. N, 9 mi. W Buffalo, 1. The bobcat, although not abundant, is generally distributed throughout Harding County, particularly in the buttes and badlands. Visher (1914:90) reported the species as common in the early part of this century. Our three specimens were shot in March 1963 by professional hunters sponsored by the Western South Dakota Sheepman Association, two from the air and one on the ground. Two other bobcats were killed in the same three-day period (March 25-27). We tentatively assign our specimens to the subspecies _pallescens_ owing to their pale color and the general agreement of their external and cranial measurements with those reported for other specimens of that race. Geographic variation in _Lynx rufus_ from throughout the Northern Great Plains is poorly documented, however, and is in need of critical analysis. External measurements of the three specimens, all males (adult and two young adults, respectively), are: total length, 870, 925, 820; length of tail, 142, 176, 155; length of hind foot, 191, 192, 178; length of ear, 82, 84, 71; weight (pounds), 23, 17, 16. Respective lengths of testes were 30, 36, and 15. Selected cranial measurements of the adult and largest young adult are: condylobasal length, 113.7, 111.5; zygomatic breadth, 88.3, 83.7; interorbital constriction, 24.5, 23.5; length of nasals, 30.1, 30.8; length of maxillary toothrow, 37.7, 38.6. Order Artiodactyla ~Cervus elaphus canadensis~ Erxleben, 1777 Wapiti or Elk Visher (1914:87) reported that the last native elk in Harding County was killed in the Long Pine Hills in 1879, and also mentioned skulls picked up in the Cave Hills. The origin of a wapiti allegedly shot in the Slim Buttes in 1956 (Robert Kriege, personal communication) is unknown, but presumably this individual was a wanderer, possibly from the Black Hills to the south where elk were reintroduced some years ago. ~Odocoileus hemionus hemionus~ (Rafinesque, 1817) Mule Deer _Specimens examined_ (6).--2 mi. N, 5 mi. W Ludlow, 1; 9 mi. N, 10 mi. W Buffalo, 2; 10 mi. S, 5 mi. W Reva, 3.
