ANALYSIS OF THE TWO EDITIONS. 



9 



Aside froi . those modifications whicli affect tlie ornitliological or scicntiflc ttnhii 

 oftlie " C'lu'ck List," the changes in noinenelaturu are numerous antl in many cases 

 radical. Witliont counting merely literal changes in the spelling of words, nominal 

 clianges are made for one or another seeming good reason in upwards of l.>0 cases. 

 In probably not more than .'50 of these, however, is the ornithological status of any 

 l»ird modified ; the changes being simply nomcnclatural. 



This portion of the subject is concluded with the following table, showing the 

 number of birds ascribed to North America by several authors who have published 

 complete lists from 1814 to the present year.

t The number ia ostensibly 7-J8 ; but b nunibers are duplieatcd in printing, and 1 species is not 

 numbered, ninkiuK 744; of wliich 22 are admitted to be extra-limital, but enumerated. 



X Total of numbered species in the body of the Cheek List 0.J5; actual number of sper-ics and 

 subspecies 750; with 28 additional in tlie Appendix, making 778. 



§ Total of iiuml)ereil species in the Catalogue 704 ; actual number of species and subspecies 024 ; 

 of which ;{7 are admitted to be extra-limital, f »r all that is known to the contrary ; and several 

 others do not ap|)ear to be fully established iiS North American. 



1 Being the 778 of the orig. eti , minus 10 subtracted, ;</«« 120 added, = 888. 



Note. Mr. Bidgway's Catalogue contains the following 52 names of birds which I do not admit 

 ...c Check List, for reasons which may be inferred from the remarks set against each of them. 

 But the Mexican (not insular) species may all be expected over our border ; and the recognition o£ 

 subspecies in some cases depends upon the perspective in which we may elect to view them.
