thirty apparently iindescrihed species and subspecies of the ])ig 
Bears—Crizzlies and big Brown Bears—of various parts of 
western America from northern Mexico to Arctic Alaska. 1 liis 
will l)c followed in the near future by more complete descrip¬ 
tions with fuller comparisons, known ranges, measurements 
and other matter, illustrated by photographs of skulls and 
teeth. 
Most of the species here published have been in manuscript 
for several years, and have been held hack awaiting the acquisi¬ 
tion of fuller material. Through the kindly cooperation of the 
])rincipal museums of America* and of a considerable numher of 
sportsnum and huntvrs, enough skulls—more than oOO—have

of most of the species, though much remains to he done in the 
way of mapi)ing their geographic ranges.
