at an earlv period, and the proportionallv few reniainins^ indi- 

 viduals and extremely limited area of today. In lyyo-iSot^ they 

 ranged at times as far north as Albany and Lake Ontario, New 

 York, and as late as 1S69 were known in the East in sontlicrn Penn- 

 sylvania. Another decade (1S7S) saw stragglers in the Mississipjii 

 Valley as far north as the jnnction of the Ohio and Mississippi 

 Rivers, while the past ten years has witnessed their being driven 

 almost exclusively to southern Florida and the Indian Territory. 

 So scarce have they become within this latter period, that it 

 would appear safe to give as their present habitat the minimum 

 areas represented in black, which cover the localities of capture 

 or observation for the last live years. 



Ill concluding, I wish to express my gratitude for the kindness 

 shown me in compiling the present paper. More especially am 

 I indebted to my friend, Mr. Robert Ridgvvav, and to the Assis- 

 tant Secretar}- of the Smithsonian Institution, Dr. G. Brown 

 Goode, for the use of the Museum material, and to Mr. A. W. 

 Butler for valuable information from his own still unpublished 

 notes on the same subject. To these gentlemen I wish to express 

 my warmest tlianks and appreciation. 



RECENT LITERATURE. 



Sharpe's 'Review of Recent Attempts to Classify Birds."* — Of tlie many 

 impriitant addresses, nieinoirs, and reports read before tlie Seeond Intei"- 

 nationai Ornithological Congress held at Budapest in Maj' last, we have 

 space to notice at present only Dr. Sharpe's notable address on the 

 Classification of Birds. Only the first 55 pages, or a little more than one 

 half of the address, is devoted to a review of previous work, the remainder 

 being given to a formal exposition of the author's own views on the sub- 

 ject. The review practically begins with Huxley's 'Classification of 

 Birds,' published in 1S67, and thus relates to the work of the last twenty- 

 five years. An epitome, with some critical comment, is given of Mux- 

 ley's system, ofGarrod's scheme (published in 1S74), of P'orbes's (18S4), 

 of Sclater's (18S0), ofNe\vton's views (1SS4), Reichenow's system (18S2),
