RODENTIA—LEPORIDAE—LEPUS CAMPESTRIS. 587 
Additional specimens received since the preceding description was written substantiate the 
identification of the white and gray hares of the upper Missouri. The summer skins vary but 
little, chiefly in a yellowish wash to the gray of the back, and in the greater or less purity of 
the white of the back of the ear. In one specimen, 456, this is of a snowy whiteness. In most 
specimens the long tail is pure white thoughout ; in others there is a slight tinge of ashy along 
the central line.' 
1The following description and measurements are taken from Prince Maximilian : 
Lepus virginimus, (campestris,) Pr. Max. Reise in das innere Nord-Amerika, I, 1839, 508. This hare in winter is entirely 
snow white, except the tip of the nose, sides of the upper lip to the corner of the mouth, upper surface of the fore foot, 
and outer border of the fore arm, which are beautiful yellowish red color, (coffee and milk). The ear is black at the tip, 
more or less yellow on the anterior edge ; down each foe of the hind feet is a bright yellowish red stripe. The incisors are 
yellowish ; the iris yellowish gray brown.
