This is tlie second Warbler peculiar to tlie olive 

 groves of classic Greece, that lias been made known to 

 science Avitliin the last twenty or twenty -five years, 

 Strickland's discovery of the bird last described in 1836 

 led to that of the present species, by Dr. Linclermeyer, 

 in 1843. Count Miihle remarks that from these events 

 we may conclude that many birds especially such as 

 from their trifling size and colouring of the plumage 

 so readily escape observation, remain yet to be discov- 

 ered. During his residence in Greece, though anxiously 

 examining the birds of that country, this species escaped 

 his observation. 



The Olivaceous Warbler is at first sight very like the 

 Olive Tree Warbler; but if we examine the dimensions 

 which afford us such valuable means of differential 

 diagnosis, we shall find a full inch difference in size. 

 Its plumage is also altogether more of a yellow tint 

 than that of its congener. It inhabits, however, the 

 same localities, the olive plantations of Attica, where it 

 also arrives late and departs early. 



Count Miihle informs us, that, like the Olive Tree 

 Warbler, it takes up its abode in the tops of the olive 

 trees, and is never seen elsewhere. As volatile and 

 restless as its congener, it is yet still more shy, flying, 

 as if in terror, from one tree to another; but after a 

 certain time returns quickly to its first resting-place, 

 and thus it deludes those who design its capture, or 

 the discovery of its nest. 



Its piercing shrill cry may be heard repeatedly from 

 its retreat; and it is continually engaged, with restless
