REVIEW OF AMERICAN BIRDS. 



[part I. 



The description of this species, as given in the Birds of North 

 America, was taken from a type specimen received from Mr. Audu- 

 bon. A second sliin, collected by Capt. Blakiston on the Forks of 

 the Saskatchewan, differs in having the tertials nearly as long as 

 the primaries (about one-tenth of an inch shorter). The hind claw, 

 too, is considerably longer, measuring .53 of an inch, instead of .46. 

 In other respects the specimens appear similar. A similar discre- 

 pancy in length of hind claw is seen in Anthus ludovicianus, where 

 it is sometimes considerably longer than the toe alone.

(277, Lawr. coll., % .) Outer four primaries very nearly equal and longest, 

 the 5th mediate between 4th and 6th. Inner secondaries nearly equal to 

 primaries. Hind toe and claw nearly equal to the tarsus ; the claw rather 

 longer than its digit, sharp, moderately curved ; outstretched toes reaching 

 the end of tail. 



Above dusky brown, the feathers edged laterally with pale fulvous ; most 

 so on the hind neck, least on the middle of the back. Beneath soiled white, 

 with a faint tinge of yellowish ; perhaps very faintly fulvous on crissum and 

 on breast. A pale line over the eye ; ear coverts and sides of neck as de- 

 scribed on the hind ne(!k ; rest of cheeks slightly specked with dusky. 

 JUgulum and sides of breast, and edge of wing on the inside, with shaft 

 streaks of dusky, which at the ends widen into arrow-shaped spots. Wing 

 feathers edged as described, the 1st primary more gray, the secondaries more 

 olivaceous. Outer tail feathers white, with a streak of dusky along the edge 

 of inner web for basal half, the next similar, with the dusky streak extending 

 nearly to the end of the inner web, and nearly as wide as the white portion. 

 (Third feather wanting in the specimen.) Bill dusky above, pale below, be- 

 coming darker to the tip ; legs flesh coior.
