is one or another of the species of rabbits or hares. The rabbit is one
of the few species of wild game that still is hunted commercially and
sold for food on the open market. The close association and repeated
contact of man with these animals has resulted in his contracting such
of their diseases as are transmissible to him. Consequently the rabbits
and hares have figured in many investigations concerned with public
health and medicine. Because the number of such investigations is
increasing, there has been an increasing number of specimens of these
animals submitted to mammalogists for identification; also, inquiries
are received as to the degree of relationship between two or more of the
named kinds of rabbits in which identical, or closely related, disease
organisms have been found; other inquiries have to do with the degree of
relationship of named kinds of rabbits and hares in widely separated
parts of the continent.

The monographs to which the investigator could turn to obtain answers to
some of these questions are Arthur H. Howell's "Revision of the American
Pikas" (1924), and Edward H. Ne
