* Although I keep distinct the synonymy of the four forms admitted by 

 American ornithologists {B. canadensis, hutckinsi, occide7italis, and minima), and 

 have added to each the description given by Mr. Kidgway, I have not been 

 able to draw the line between them and to recognize more than two species — 

 one (-B. canadensis) extremely variable in size, and found nearly all over 

 N. America ; and a second, very much smaller and not very variable in size, 

 confined to Alaska during the breeding-season, but, according to the American 

 authors, extending to California in winter. Of the first species, besides other 

 specimens, there is in the British Museum a series of 7 specimens from Corpus 

 Christi (Texas), fully adult and young, whose beaks vary from 2'3 to l"! 

 inches, and all the other parts accordingly. They show such a perfect transition 

 from one to another, that their specific identity cannot be questioned for a 

 moment.
