A FIRST LIST OF THE BIRDS 



Now I have most carefully measured the 34 black and white 

 specimens that my museum at present contains with the follow- 

 ing results : — 



less than 3 inches, and that 29, or 88 percent., have the tarsi less 

 than 3*1, and that in only one single specimen does the length of 

 the tarsus exceed 3'12. These measurements, it will be under- 

 stood, have been taken with the greatest care, and verified by 

 two persons, so that they may be depended upon to the 100th of 

 au inch where the tarsi are concerned, and one-tenth of an inch 

 where the win^s are concerned.
