letter in the subjoined references indicates that the species is referred 
to as Ammodramus australis; the key letter “a” indicates that the 
species is mentioned by one of the English or vernacular names, 
without any Latin equivalent; “b” indicates the combination Co- 
turniculus australis; “ce” Ammodramus passerinus; “d” Coturnic- 
ulus passerinus; and “e” Fringilla australis, 
As the work progressed the committee was convinced that several 
changes might be made with advantage and some of the matter 
eliminated without serious loss but in order to have the Index uni- 
form with the previous volume it was deemed advisable to introduce 
no innovations which might interfere with this object. Conse- 
quently only three minor changes have been made viz. : 
(a) Use of black face type for every entry accompanied by a 
page reference, and the smaller Roman type for cross references. 
Thus greater uniformity is secured and a glance is sufficient to dis- 
tinguish secondary references by the less conspicuous type. 
(b) Insertion of dates of birth and death after names of de- 
ceased authors. 
(c) Inclusion in the Introduction of a special Index to all the 
biographical matter thus far published in “The Bulletin of the 
Nuttall Ornithological Club” and “The Auk” in order to bring 
together in one place a convenient list covering all the volumes from 
1876-1914.

AUTHORS’ NAMES 
Modern bibliographical standards require full names of authors 
with date of birth, and for deceased authors, dates of birth and 
death. In the former Index full names were obtained when pos- 
sible and in the present work dates have been inserted after names of 
deceased individuals, but no attempt has been made to ascertain the 
dates of birth of persons who are still living. The same care has 
been exercised in preserving the full names of authors in original 
form as in ascertaining the original spelling of names of genera or 
species. In following this rule additional names of several well- 
known ornithologists have been brought to light. few persons 
realize that John James Audubon was not Audubon’s full name. He 
himself says in a letter to Mrs. Rathbone in 1827: “ My name is
