Tt/pe. ? , Norton Bay, Alaska, Oct. 1879, E. W. Nelson, 

 No. 96776, U.S. Nat. Mus. 



There was one white bird taken at St. MichaePs, Alaska, 

 but not breeding, which I judged to belong, not to F. r. 

 candicans of Greenland and Arctic America, but to the 

 Bering Island colony, which is a small white race. 



The Old World Gyrfalcons are correctly designated by 

 Dr. Hartert, and with the addition of the above renamed 

 form the circle is, I believe, completed and the confusion 

 of the American races, as evidenced in the 1910 A. 0. U. 

 Check List, cleared up. 



Mr. David Bannerman sent the description of the 

 following new West African birds : — 



Fraseria ocreata kelsalli, subsp. nov. 



Adult. Distinguished from F. o. ocreata by having the upper 

 parts uniform grey and the breast white, and by having the 

 feathers of the breast, flanks, and under tail-coverts broadly 

 margined with grey — very distinct from the typical species, 

 which has the breast-feathers narrowly margined with black 

 and the head darker than the back. In this latter character 

 it resembles F. o. prospJiora Oberliolser, but may be readily 

 distinguished from that form by the markings on the breast. 



Bill 15 ; wing 87 ; tail 65 ; tarsus 21 mm.
