place their nests on a tree or bush. All our European Thrushes deposit more or less spotted or 

 blotched eggs ; but many of those inhabiting other regions, notably several of the small American 

 Thrushes, lay unspotted eggs. All the Palaearctic species are spotted in nestling dress. 



Turdus viscivoras, the type of the present genus, has the bill tolerably strong, slightly 

 declined and notched ; gape furnished with a few bristles ; nostrils elliptical, direct, in the 

 lower and fore part of the nasal membrane, which is feathered; tarsus covered in front with 

 a lon» plate and four inferior scutella?, posteriorly with two longitudinal plates ; feet and claws 

 moderately strong ; wings rather long, rounded, first quill very small, third and fourth longest ; 

 tail slightly emarginate, composed of twelve feathers. 



White's Thrush, which I also include in the genus Turdus, differs from the other Western 

 Paleearctic Thrushes in having fourteen instead of twelve rectrices.
