SYSTEMATIC TABLE

Of the Birds of America north of Mexico, arranged according to the

American Ornithologists' Union's 'Check-List of North American Birds',

Third Edition 1910, and Supplement[B], July, 1912.

(_The presence of brackets, [ ], indicates that the species is an

accidental visitant_).

[B] 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.)

[E] 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.
