After an historical introduction, the anatomy of each genus is treated 
of in regular order ; the classification is then w r orked out, three families 
being recognized :—(1) Procyonidce , with subfamilies Procyonince and 
Ailurince ; (2) Mustelidce , with subfamilies Melince , Mustelhice , and 
Lutrincc ; (3) Ursidce. Finally the distribution is treated of : the Procyo¬ 
nince are exclusively New World forms; the Ailurince Asiatic; the 
Mustelidce and Ursidce cosmopolitan within the range of the suborder.
