io8 STRA Y FEA THERS FROM MANY BIRDS. 



tion. It is notorious that the nests and the eggs of 

 birds in the genus Sylvia vary exceedingly, even among 

 allied species, so that those of Tristram's Warbler may 

 be very different from those of other known species. I 

 may remark in conclusion that this little bird tries hard 

 to hide itself under leaves and in holes when wounded, 

 and I have seen it creep into crevices when scrutinised 

 too closely. 



The specific name of this little Warbler is a most 

 inapplicable one the bird is no more a desert species 

 than the Cuckoo, the Redstart, the Pied Flycatcher, 

 and scores of others which spend the winter in the 

 oases of the Sahara. I have therefore deemed it 

 advisable to rechristen this bird Sylvia algeriensis^ its 

 breeding-place and true home being, so far as is at 

 present known, confined to the wooded slopes of the 

 Aures Mountains, in the province of Constantine.
