him from the two most nearly allied species, and particu- 
larised in his letters to his friend Pennant in the year 1768, 
but the bird does not appear to be included in the edition 
of the British Zoology published in 1776. The first edition 
of White’s Natural History of Selborne, which contained 
several notices of this bird, was published in 1789. In 
November 1792, Mr. Thomas Lamb supplied some par- 
ticulars of this same bird to the Linnean Society, which 
were published in the second volume of the Transactions of 
the Society ; and in 1796 Colonel Montagu, having seen 
and heard this species in various localities in several 
western counties, and having obtained also some specimens, 
nests, and eggs, furnished further particulars to the Lin- 
nean Society, which were published in the fourth volume of 
the Transactions. This bird is now very well known, and 
is at once distinguished from the true ¢rochilus, or Willow 
Warbler, with which it is most likely to be confounded, by 
the broad streak over the eye and ear-coverts of a bright 
sulphur-yellow, by the pure green colour of the upper parts 
of the body, and by the delicate and unsullied white of the 
belly and under tail-coverts. In addition to these distine- 
tions, which on comparing the two birds will be found very 
obyious, the wing of the Wood Warbler is nearly half an 
inch longer from the carpal joint to the end of the quill- 
feathers than that of the Willow Warbler, although the 
birds themselves differ but little in their respective whole 
lengths: the wings of the Wood Warbler when closed 
reaching over three-fourths of the length of the tail, while 
those of the Willow Warbler, next to be described, reach 
only to the end of the upper tail-coverts, or less than half 
way along the tail-feathers. The two birds here named, 
and a third species, the Chiff Chaff, so called from its par- 
ticular note, are the only British species now included in
