INTRODUCTION. 



The succession of families and genera followed in this paper 

 is that of the American Ornithologists' Union. Trinomials are 

 applied according to A. O. U. canons of nomenclature, z. e., 

 when forms overlap in their variations, regardless of the pos- 

 sibility or impossibility of their interbreeding, they are called 

 subspecies. A number is given to each species of a genus, and 

 this number is intended to stand, not for the form first named, 

 but for the sum of all the subspecies, where subspecies that 

 compose the species occur, not this number and a letter for 

 each of the other subspecies as in the A. O. U. Check List. 

 Each variety of a species is lettered. Thus : 63, Geosfizafor- 

 tis consists of 63^, G . fortis fortis ; 63^, G. fortis fratercula, 

 etc.; not 63, Geosfiza fortis; 63a, G. fortis Jratercula, tic.
