explanations. 



The nomenclature is that of the forthcoming third edition of the American 

 Ornithologists' Union Check List. Although the species are not to be num- 

 bered in this work, I have added the numbers of the previous edition of the 

 Check List at Mr. Morse's request. 



Where two dates of arrival appeai;, the first is the average date of first ar- 

 rival, that in parentheses the bulk arrival (see p. 32). Quotations from the 

 works of Wilson and Audubon, Abbott's List (1868), Turnbull's (1869) and 

 Thurber's (1887) are usually not accompanied by page reference, but all other 

 published records are accompanied by footnote references. Full titles of all 

 publications on New Jersey birds will be found in the Bibliography on p. 317.
