PLAN OF THE INDEX 
The general plan of this Index is the same as that of 1907, which 
was described by the editor, Dr. Jonathan Dwight, as follows: 
1. “AutnHors. ‘Titles of papers are in chronological order and in 
condensed form. Reviews and notices are indicated by the ab- 
breviation ‘(rev.),’ which is used alone when the author is reviewed, 
and by the additional word ‘see’ prefacing the paragraph when the 
author is reviewer.” 
2. “Locauities. Names of authors in alphabetical order are 
placed under each.” 
3. “GENERA. Species in alphabetical order are indexed under 
their respective genera, subspecies or races being, for indexing con- 
venience, treated like species and the middle term of the trinomial 
dropped. Under species, the page references are arranged by states 
and countries in alphabetical order, and, set off by a dash, at the 
end of the localities are additional categories in which are put refer- 
ences to matters other than distribution. . . . The scientific names 
adopted are those of the A. O. U. Check-List [of 1910] with ap- 
proved corrections to the end of 1912, and for foreign species, as a 
rule, partly those of Sharpe’s ‘Hand List’ and partly those of 
Ridgway’s ‘ Birds of Middle and North America’ to date [of 1914]. 
An asterisk indicates an original description . . . and an interroga- 
tion point a reference doubtfully placed.” 
4. “SYNONYMS OR Cross REFERENCES. Each refers directly to 
the name with which it is synonymised in this index and some are 
merely cross references rather than actual synonyms. Vernacular 
names in modern foreign languages have been discarded.” 
5. “ MisceLLANEous Items. Everything not provided for in the 
other primary divisions is included in these items, such as notices 
of journals and the classified subject matter of body articles under 
various headings such as ‘ Distribution,’ “ Migration,’ ‘ New Species,’ 
‘ Nidification’ and many others.” 
6. Key Letters. Each name of a species that occurs in the A. 
O. U. Check-List is followed by the English name given it in that 
Check-List. If any English or vernacular name is used for this 
species in ‘The Auk’ without a Latin name, then the key letter “a” 
precedes the English name in the index and this same key letter is 
added to every reference in which this species is mentioned without 
a scientific name. Following the English name is a list of all the 
Latin synonyms each with its own key letter. Thus under Am-
