Note B — Front matter (continued 6)

The Auk, xxix, 1912, pp. 380-387.

[C] Note that trinomials are now employed for all the races of a species including the first one described. Hence in place of No. 13, Puffin, Fratercula arctica, we now have No. 13, Puffin, Fratercula arctica arctica. (See pages 6 and 7 for an explanation of this method.)

[D] Note also that in accordance with a ruling of the A. O. U., the apostrophe is used with the names of birds named after individuals. Thus in place of No. 16, Cassin Auklet, we have No. 16, Cassin's Auklet. These changes affect all similar cases throughout the Color Key. After identifying a species, therefore, the student should turn to its number in the Systematic Table to learn whether any change has been made in its name. All alterations other than those of mere nomenclature are given beyond in Appendix I.
