ed with a number of text illustrations. 

 A map of the region, also five colored 

 plates by George M. Sutton, than 

 whom there are few, if any better 

 bird artists in America. The entire 

 volume is up to the usual standard of 

 the authors, which is equivalent of 

 saying that it could not well be im- 

 proved on. We predict that for years 

 to come this will be the standard book 

 of reference relating to the birds of 

 that region. — R. M. Barnes. 



Changes and Additions to the A. O. U. 



Check-List of 1910 



By J. Hooper Bowles 



The readers of "The Oologist," who 

 are not acquainted with the A. O. U. 

 check-list as it stands at present, may 

 well have become somewhat uncertain 

 owing to the discussion in recent 

 numbers of the magazine concerning 

 the new egg catalog. Consequently I 

 will attempt to clear up matters as 

 briefly as possible. 



When I wrote my letter of July 15, 

 1922, I had been given the hope that a 

 committee of the A. O. U. might be ap- 

 pointed in the fall to consider the vast 

 number of suggested changes and ad- 

 ditions to our list. For this reason I 

 strongly urged that no action should 

 be taken on considering valuations 

 for the very few additions made since 

 1910, because a vast deal of time 

 would be saved if all the changes 

 could be considered at once. This was 

 taught by experience with the catalog 

 itself. However, no further action 

 having been taken on new additions, 

 etc., at the recent A. O. U. meeting. 

 I am giving herewith all of the ad- 

 ditions made to the 1910 checklist 

 up to date. No eliminations, what- 

 ever, have been made since its publi- 

 cation in 1910, except those given 

 here. 



Up to date the only additions to the 

 1910 A. O. U. check-list may be found 

 in the Sixteenth Supplement, which 

 appears in 'The Auk" for July, 1912.
