218 Messrs. G. M. Matliews and Tom Iredale : 



However, in making this designation, the A, 0. U. Com- 

 mittee must have overlooked the fact that Gray in tlie Cat. 

 Gen. & Subgen. Bii'ds, 1855, p. 125, had selected as tvpe of 

 " Colymbus Linn. 1735 nee 1766, C arcticus Linn.'^ 



The direct statement that it is not the type of Linne 1766 

 bat of Linne 1735 necessitates its acceptance as the type of 

 Linne 1758. This is obvious to anyone conversant with 

 Gray's methods of working, and as C. areticus is the first 

 species of Colymbus Linne 1758, this must be accepted as 

 the type. We are certain that American ornithologists will 

 now consent to accept this as finally settling a matter which 

 has been a bone of contention for too many years.
