 In 1838 Dr. Kirtland had not met with the American Crossbill [Loxvt 

 curvirostra minor) in Ohio and Indiana. Dr. Haymond omitted it from his 

 " Birds of Southeastern Indiana" in 1856. Dr. Wheaton reported it from 

 Ohio in the winter of 1859-60. Evidently it was quite well known to Dr. 

 Haymond in 1869. The winter of 18(18-9 they were very abundant in tie 

 vicinity of Cincinnati. (Charles Dury.) This was doubtless the case at 

 other places also. The range of the species at this time was supposed to be 

 northern North America, south in the Appalachian mountains into Penn- 

 sylvania, extending in winter, irregularly over much of the United States. 

 A letter from Mr. C. E. Aikin, of Salt Lake City, Utah, informs me that 

 this species became very abundant in the city of Chicago in July and 

 August 18(>!>, and remained until late in the fall. They fed greedily upon 

 seeds of sunflowers and were so sluggish that one could approach within 

 a few feet of them so that they fell an easy prey to boys with catapults. 

 In the latter part of August of the same year, he found them common in 

 Lake county, Indiana. He also notes that they were not rare the suc- 

 ceeding year in the vicinity of Chicago. Dr. F. W. Langdon notes the 

 capture of a single specimen from a Hock of six or eight at Madison vill«\ 

 near Cincinnati, <>., Nov. 30, ls74. In the winter of 1874-5 Mr. Eugene 1'.
