PLATE 3. 



Antlers of blaek-tail deer {Odncoilcus columhicmus sitkensis) from south- 

 eastern Alaska. Those on the right from C'hichagof Island, on the left 

 from islands south of Frederick Sound. Note the difference in the fork- 

 ing; in the series on the left the branching tines are conspicuously forked, 

 while in those on the right they are straight.
