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. 1 



'The 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 

 gnow 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 toe of the hind feet is a bright yellowish red stripe. The incisors are 

 yellowish ; the iris yellowish gray brown.
