246 NEBRASKA ZOOLOGICAL STUDIES 
The usual form of reference has been followed. A number corre- 
sponding to the year of publication precedes each title, and brevity of 
citation is secured by referring to a title by its number; thus, “Bruner, 
96” refers to his Notes on Nebraska Birds. What is supplied by the 
compiler is placed between brackets, including the insertion of a title 
where in the original reference there was none. Capital Roman nu- 
merals in the citation of an article refer to volumes, lower case Roman 
and Arabie to pages. The annotations under each title are intended 
merely to supplement the title in suggesting to the reader the character 
of the reference.
