APPENDIX, 
I Here append the following list of additional species, which occur 
or have occurred within the limits of New England. As will be 
perceived, the greater number can be regarded only as occasional 
or accidental visitors ; and, indeed, some of the species are deemed 
by ornithologists as of doubtful existence, — as, for instance, Small- 
headed Flycatcher, Wood Wren, &c. 
I am under special obligations to Mr. Henry A. Purdie for 
many valuable suggestions and facts in relation to the times of 
arrival, distribution, breeding habits, &c., of many of the species 
described in the body of the work, and mentioned in the Appendix.
