this inequality is owing to the manner in which the skins have 
been prepared, or whether it is natural, is not for us to deter- 
mine. ‘The present individual is the only specimen Mr. Caley 
ever met with: it was much shattered by the contents of his 
gun. !

The birds of this genus appear to belong to that subdivision of 
the Thrushes, which by the weaker conformation of the bill opens 
a passage to the slender-billed Warblers. They deviate very 
considerably from the typical form of the Merulide. Besides 
the more gracile shape of the bill, the nares may be observed to 
be linear and longitudinal, instead of being rounded, as in the 
true Turdi. The wings are short and rounded, the first quill- 
feather being of moderate length, and the next gradually in- 
creasing ; they thus differ from the wings of Turdus, where the 
four quill-feathers succeeding the first are nearly of equallength,
