 Motacillida', with the plumage more or les.s streaked, tail decidedly 

 shorter than wing, the under parts neither pure white/' yellow,*'^'' 

 orange/' nor red,'' ]»ut more or less huffy or cinnamomeous, and more 

 or less streaked, at least on sides, and without black on chest or throat, 

 except in form of streaks; planta tarsi not scutellate, except the lower 

 portion. ' 



^«;if/t.— Cosmopolitan (wanting onlj- in Papuan islands and Poly- 

 nesia). (Numerous species.) 



Ifidiji cation. — Nest on ground, among grass tufts or rocks, open 

 above, composed of grasses, etc., lined with softer materials; eggs 

 profusely speckled with brown, often so densely as to appear almost 

 uniformly of that color. 



The above combination of characters will serve to readily distinguish 

 this genus from other Motacillidse. I have not been able to satisfac- 

 torily subdivide the group, for. notwithstanding very marked varia- 

 tions in relative length of the hallux and its claw to that of the middle 

 toe and tarsus and in the wing formula, there seems to be no correla- 

 tion of these variations with one another or with other characters, 

 while at the same time the most extreme variations seem to be con- 

 nected by intermediate conditions. This is apparently the case both 

 as to JS^eoeoryx and Xanthoeorys: and if these are recognized as genera 

 it will certainly be necessary to recognize other groups as of equal 

 rank. 



KEY TO THE SPECIES OK ANTHI'S. 



(I. Sixth primary conspicuously longer than fifth, the difference between them very 



much greater than that between fifth and fourth: wing more than 7J^ mm. 



(usually very much more). 



h. Hallux and claw together not longer than middle toe and claw and shorter tluin 



tarsus. 



c. Rump and upper tail-coverts not streaked; second rectrix partly white. 



(North America.) Anthus pensilvanicus {\>. 12) 



oc. Rump and upper tail-coverts conspicuously streaked with darker. (Northern 

 Europe and Asia, south in winter to northea.stern .Vt'rica aii<l southern Asia; 

 accidental in Alaska and Lower California.) Anthus cervinus (p. 15)

 wrongly cited as 15 (as also in case of Nntincorys).
