Troglodytes, Cuv. 



The only difference between the Wrens and the present subgenus 

 is, that in the latter the beak is still a little more slender and slightly- 

 arcuated. But one species is found in Europe. 



Mot. troglodytes, L.; Roitelet, Enl. 651, 2; Naum. 83, 4. (The 

 European Wren.) Brovvn, transversely striated with black; 

 some white on the throat and the edge of the wing; a turned-up 

 and short tail. It builds on the ground, and cheers us with its 

 pleasing song even in the middle of winter. (1) 



MoTACiLLA, Bechst. 



The Wagtails, to a still slenderer beak than that of the Eau- 

 vettes, add a long tail which they are continually raising and de- 

 pressing, long legs, and scapular feathers sufficiently extended to 

 cover the tip of the folded wing, which gives them an affinity with 

 the greater number of Waders. 



MOTACILLA, Cuv. 



The true Wagtails still have the nail of the thumb curved like 



the rest of the group. They live along the shores of water courses. 



That of France {Mot. alba and cinerea, L.), Enl. 652, is ash 



coloured above, white beneath; a calotte on the occiput; throat 



and breast, black. 



The south of Europe produces one which when old has a 

 black back, but resembling the preceding when young. It is 

 the Mot. lugubris, Roux, 194. 



BuDYTEs, Cuv. (2) 



In addition to the other characters of the true Wagtails, the nail 

 of the thumb is here elongated and but slightly arcuated, which 

 approximates these birds to the Larks. They generally remain in 



1; S. speciosa, lb. 2; S. palpebrosa, Ib.,&c. &;c. Those whose beak is somewhat 

 broad at base, are closely allied to the narrow-beaked Flycatchers. For the cata- 

 logue of species in the United States, see the paper by M. Ch. Bonaparte. Ann. 

 New York Lye. July 11, 1826, p. 76, et seq. See Jpp. XVIII of Am. Ed. 



(1) The Wrens foreign to Europe are allied to the Ant-catchers on the one 

 hand, and to the Creepers on the other. Add the Thriotwe a long bee ( Tlir. lon- 

 girostris, Vieill. Gal. 168, or Kampylorhynchus scolopaceus, Spix, 79). [Add 

 Trog. uedon. Wils. I, pi. iii, f. 3; Trog. palustris [Thyothorus arundinaceus, 

 Vieill.), Wils. II, pi. xii, f. 4; Trog. ludovicianus {Sylvia ludoviciana, Lath,) 

 Wils. II, pi. xii, f. V. Jm. Ed.} 



(2) Budytes, from its being seen among cattle.
