ing name of reciirostrh ; although I am more inclined to think 

 it constitutes a distinct genus. 



Troglodj/tis, originally instituted as a genus by our illus- 

 trious countryman Ray, has been adopted both by M.M. 

 Cuvier and Vieillot. Professor Temminck, on the contrary, 

 has included it with Si/lvia; an immense genus, already bur- 

 thened with more species than are rightly understood, or that 

 really belong to it. 



Figure the natural size. Bill straight, triangular at the 

 base, the sides compressed, tip of the upper mandible bent 

 down and notched ; nostrils large, lengthened, covered by a 

 membrane, which (except at the base,) is naked ; the aper- 

 ture terminal, near the edge of the bill, narrow, and oblong : 

 the feathers on the rump and flanks remarkably long ; the 

 three fore toes slender, and all connected at their base as far 

 as the first joint: tail even, and longer than the generality of 

 Wrens, the feathers very narrow, weak, and deep black. 

 Plumage above light or reddish brown ; sides of the head, 

 neck, breast, and body, the same, but tinged with fulvous ; 

 the chin and upper part of the throat blackish, but the 

 margin of the feathers partly white : lower part of the throat 

 and breast dusky : middle of the body pure white ; under wing 

 covers, inside margin of the quills, and edge of the shoulders, 

 white. 



Mr. Leadbeater favoured me with this bird, which he re- 

 ceived from Brazil. 



The comparative length of the bill in this genus, (leaving 

 the present bird out of consideration,) offers no generic dis- 

 tinction, because it varies greatly in different species. Some 

 of those found in Brazil have the bill nearly double the length 

 of the common Eurooean Wren.
