2. The names in the Dictionary arc numbered to correspond, each page containing the 

 same nmiibers of the two series. 



3. Tlie person's name in parentheses immediately after each bird's name is that of the 

 original describer of the species or 8ubs)H'cie8. The unenclosed name succeeding is that of the 

 authority for the particular combination of generic, specific, and subspecific terms adopted. 

 When the original describcr is also the authority for the combination, a single unenclosed 

 name is given. — The following arc the principal abbreviations: —

 Catalogue, 1880. The number following each of these letters is that which the bird bears in 

 such lists. Thus, Tardus migratorins was named by Linna;us, who is also the authority for 

 the combination, and is l.'iS of Baird's list, 1 of Coucs's, and 7 of Kidgway's. The dash 

 .ifter any one of these letters shows that the species is not contained in B, C, or R, as the
