Ghaes. — In general form, scarcely distinguishable from Den- 

 drceca; larger in size, different in pattern of coloration, in 

 habits, gait, and nidiflcation. Bill ordinary. Eictal bristles 

 short but evident. Wings pointed, much longer than tail. 

 Tarsus longer than middle toe and claw. Tail nearly even, 

 with rather acute feathers, and long, copious under coverts. 

 Size larger than in Dendrceca. Neither wings nor tail parti- 

 colored. Above olivaceous, with or without head-markings, 

 otherwise uniform ; below white, buffy, or yellowish, profusely 

 streaked. Legs slender, i)ale-colored. Habits terrestrial to 

 some extent ; nest on the ground ; eggs white, spotted. Vocal 

 powers preeminent. Gait ambulatorial, not saltatorial, and 

 some other traits decidedly Motacilline. 



This genus has held its position in the system by very uncer- 

 tain tenure, having been referred to various families, as the 

 TurdidcB, MotacillidcB, and Sylvieolidce. It is difficult to see how 

 it differs in any important particular of structure from such a 

 Sylvicoline genus as Dendrceca for instance, and it seems much 

 better located here than among the Wagtails, notwithstanding 

 the fact that it resembles these birds in many points of its econ-
