Although I have copied the synonomy for the several varie- 
ties of our common hare as given by Allen it must be admitted 
that, save as to the last, it requires hair (hare) splitting nicety 
to make out any distinctions which will notbe utterly invalidated 
by individual variation. In general the southern L. americanus 
has a less reddish cast of the summer pelage and the part of the 
hairs which becomes white in winter is restricted. The period 
during which the winter pelage is worn is shorter, but the varia- 
tions in size are so insignificant as compared with individual 
variation as to present no basis for remark. There is, of 
course, the probability that the ultimate size of the northern 
specimens will be found greater, but the facts thus far col- 
lected give but negative results. Variety americanus in its 
typical form does not enter the United States so far as known. 
The var. washingtoni, though originally supposed to be much 
smaller appears to be simply a more fulvous form with the 
felage soft and full. Though this variety is said not to un- 
dergo a seasonal change about Puget’s Sound, its pelage seems 
elsewhere to have a deeper outer white zone in winter than the 
previous varieties.
