This very apjireciahly diffeient race re]>laees the restricted var. passcn'nt's, 

 ill tlie Western Provinee of the United States. In its paler eidors and 

 niiu'ii more slender hill than its eastern rejaesentative, it agrees with Pasaer- 

 ruhis (ilamllmix, }\m:a't<'s ronjinis, etc., as coni])ared with P. savauaa, P. yra- 

 mim us, etc. It is to this race that the hioorajdiical notes in the preceding 

 article refer, as far as baseil on western specimens.

Ammoilramufi, Swainson, Zoiil. .lour. Ill, 1827. (Tvjh', Orwlus oiudacutiui, Om.) 



Gkn'. Char. iJill very long, slen<lcr. and attenuatcil. considerably curved towards the 

 tip above. The gonys straight. A decided lol»e in middle of cutting edge of upper bill. 

 The legs and toes are very long, and reach eonsideraltly beyond the tip of the short tail. 

 The tarsus is about equal to the elongat«'<l middle toe; the lateral toes equal, their clav/s 

 falling consideral»ly short of tin* base of the middle one; the hind claw equal to the 

 lateral one. Wings short, reaching only to the l)ase of the tail ; much rouiuled ; the 



secondari<'s and tertials e<pial, and not much 

 shorter than the primaries. The tail is rather 

 shorter than the win<rs, and graduated laterally ; 

 each feather stillened, lanceolate, and at-ute. 



Color. Streaked above and across the breast; 

 very faintly on the sides. 



The essential characters consist in the 

 slender and elongated hill ; the h>nglegs 

 reaching considerahly beyond the tail, 

 with the lateral claws falling considera- 

 bly short of the middle one ; and the 

 very short rounded wings, rather longer than the cuneate tail, with its stif- 

 fened and lanceolate feathers. .
