equaling the fifth; bill moderately lengthened, the wing four to four and 

 one-half times the length of exposed culmen; length of exposed culmen 

 about twice the height of bill at base ; height of bill at base about three- 

 fourths of length of gonys; exposed culmen much less than middle 

 toe without claw, often barely more than length of the two basal 

 phalanges. 



Type. — Oriolus caudacuhis Gmelin. 



Remarks. — The above-given characters clearly show that the 

 sharp-tailed sparrow {Oriolus caudacittus Gmelin) is not con- 

 generic wdth the seaside sparrow {Fri?igilla maritima Wilson). 

 The applicability of the generic name Ammodramus Swainson 

 has already been fully discussed. "^ 



Some recent authors have considered the Nelson sparrow 

 {Ammodramus caudacuhis nelsoni Allen) specifically distinct 

 from Ammospiza caudacuta, but the examination of a large 

 amount of material now shows that intermediate specimens 

 of varying degrees entirely connect the two, and that con- 

 sequently the former must be a subspecies. The same is true 

 of the Acadian sharp-tailed sparrow {Ammodramus caudacutus 

 subvirgatus Dwight), which authors now consider a subspecies 

 of Ammospiza caudacuta nelsoni. 



The forms of this genus should, therefore, now stand as 

 follows : 



Ammospiza caudacuta (Gmelin). 

 Ammospiza caudacuta subvirgata (Dwight). 

 Ammospiza caudacuta nelsoni (Allen).

 monotypy, Ammodramus lecontei [= Emberiza leconteii 

 Audubon]). 



Chars, gen. — Similar to Ammospiza, but tail about equal to wing 

 (sometimes a little shorter, sometimes sHghtly longer); first primary 

 (counting from the outennost) longer than the fifth; bill short, but 

 moderately slender, the wing five to five and one-half times the length 

 of exposed culmen. 



Description. — Tail slightly longer to slightly shorter than wing, 

 usually about equal to wing ; first primary (counting from the outermost)
