quarters of an inch longer, and weighs two drams and 

 a half; while the latter weighs but two : so the songster 



which does not occur in loquax, the under edge of the wing is bright 

 yellow, while in loquax the yellow, if any, is faint. In Mr. Sweet's bird 

 there was no yellow ; in the specimen before me there is a little, the 

 bird being probably a young one. From the figure by Werner, I con- 

 clude that young males of rufa have the under parts very yellow in the 

 autumn, like those of Trochilus. The absence of the ch iff chaff from the 

 north of England renders it improbable that it should ever stray into the 

 northern parts of the continent, and it is not likely to occur in Sweden. 

 The pouillot of Temminck is the largest of the five, its wing measuring 

 five inches and one-eighth; the second feather is shorter than the third 

 and fourth, longer than the fifth. I have made exact representations of 

 the first portions of the wings of the five species, by which they may be 

 recognised. 



The four allied species which frequent our island, besides the golden 

 wren, are as follows. 



1. Sylvia sylvicola, MONT. ; sibilatrix, subsequently, of Bechstein ; wood 

 wren. This bird cannot easily be confounded with the others, being 

 readily distinguished by the shivering motion of its wings in the latter 

 part of its short and hurried song. It is much brighter coloured than 

 the Sylv. Trochilus. The upper parts are of a yellowish green, the tail, 

 quills, and wing coverts being edged with that colour, and brownish in 

 the middle. Above the eye a yellow line; a dark line passing from the 

 bill to the eye, and behind it; the throat and cheeks yellow; the under

parts pure white. In its habit it is much less erect than Sylv. Trochilm.
