Franklin ground squirrel[< Sir John Franklin, English explorer, 1786-1847]
a gray ground squirrel, Spermophilus franklini, found on the prairies.
1941  The gray or Franklin ground squirrel [is] notable for its loud, ringing, musical call-note.
1955  Apparently he was even more interested in nature study, for he described many plants, animals, and birds of Alberta, which he named for himself and Sir John Franklin--the Franklin ground squirrel, the common Franklin gull, the Richardson kangaroo rat. . . .
