SECOND PREFACE. 



The first two parts of rhe present edition of this work, were issued in May, 1889. 

 The following year two or three additonal parts were distributed to subscribers, but it 

 was not until October, 1894, that I began to print the bulk of tlie book, and part forty, 

 with the concluding index, was issued December 24th, 1895. 



I wisli to thank my many subscribers, one and all, for tlieir kind patience during 

 this unavoidably irregular method of issuing the parts. 



Believing, as I do, tliat our avian nomenclature is still in an unsettled, and in a great 

 measure transitional, condition, I have not considered it advisable to give a concordauce 

 of my names and those of the American Ornithohjgist's Union which I have mentioned on 

 the preceding page.
