♦ 
organism from another determines its fitness to be named trinomially rather 
than binomially In a word, intergradation is the touchstone of 
trinomialism.” The later A. O. U. committee, which prepared the Revised 
Edition of the Code, accepted these remarks without change, but added that 
‘Two kinds of intergradation, however, may be recognized; (1) ordinary or geo- 
graphic intergradation, and (2) intergradation due to individual variation in 
forms inhabiting isolated areas.” Doctor Merriam is of course right in his 
statement that intergradation is often assumed rather than proved. But at 
any rate the author of a revision, by the use of the trinomial, can show that he 
believes that intergradation does take place as indicated; and as he has given 
the group close study and not infrequently has examined a very large amount of 
material, his opinion on the matter would seem to have a certain definite value 
to others.
