OF ORNITHOLOGY 41 



the former still appeal to us as a Ihrush — a typical Thrush — 

 that we can hardly bear to separate it from the genus Turdus, 

 especially as this involves, to a very great extent, new genera 

 and new relations for the remaining individuals of the sub- 

 family. 



Sub-family /; MIMING Mocking Thrushes 



Bill much as in Turdince, but usually slender, long, and 

 curved — often in a remarkable degree ; first quill of the wing 

 nearly one-half as long as the second ; tail equal to or longer 

 than the wings ; wings short and somewhat saucer-shaped ; 

 tarsus with (mostly) distinct scutellse. 



Genera, Oreoscoptes, The Mountain Mocker. 



Mimus, The True Mockers (2 species). 

 Harporhynchus, The Thrashers (10 species). 



Sub-genera, None, unless we admit Galeoscoptes in place of Mimus for 

 the Catbird, — but, in so doing, we must raise it to the rank of a genus, 

 which there seems to us no especial reason for doing. It is pressing a 

 point, somewhat, even to insist upon making Oreoscoptes distinct from 

 Mimus, — yet this is pretty generally conceded, at present, though applied 

 to but a single species. 



Sub-family c CINCLIN-SI Dippers 



Bill shorter than the head ; nostrils in slits (linear), open ; 

 no rictal bristles ; tail short and square ; wings longer than 

 tail ; first quill about one-half the length of the second ; with 

 booted tarsus. (Aquatic.) 



Genus, Cinclus, The Water Ouzel. 



Sub-genus, None. The sub-family itself being formed for a single species 

 apparently quite constant. 



Sub-family d SAXICOLIN-ffl Chats 



Bill shorter than the head, small and weak ; nostrils oval 

 and rictus with bristles ; wings long and pointed with first 

 quill very short (spurious) ; tail short, emarginate, or squared ; 

 tarsus booted and generally but not always longer than the 

 middle toe and claw.
