Hab. Canada, Dr. McCulloch and Dr. Hall. — Specimen in the 

 private collection of the 'late Dr. McCulloch, now possessed by 

 Mrs. McCulloch. 



Frequently after having examined this bird, the late Dr. 

 McCulloch and myself considered it new, but we had no means 

 of verifying our opinion, until the visit of Prof. Cassin, of Phila- 

 delphia, in 1854. Dr. McCulloch fell a victim to the cholera dur- 

 inir its epidemic of that year, and the following spring it was for 

 warded to Mr. Cassin, in Philadelphia who identified it as a new 

 species. Only one specimen has as yet been obtained in this coun- 

 try, although Mr. Cassin has had the good fortune to secure a second 

 specimen, which now constitutes the representative of this Buteo 

 in the museum of the Academy of Natural Sciences, Philadelphia.
