PREFACE. 



The writer of the following notes has no pretension to the title of 

 " naturalist", and deprecates criticism of any technical errors that may 

 be found in his descriptions of the species. 



He wishes to acknowledge the kind courtesy of Dr. Elliott Coues, 

 U. S. A., who has undertaken to edit these notes, and has encouraged 

 him to offer them for publication.
