This genus differs from the true Thrushes (Turdus) chiefly in its shorter, more 

 rounded wings and in its long slender tarsi — characters suited to the terrestrial habits 

 of all the species, and to their place of abode amongst dense brushwood or primaeval 

 forest. Twelve species are now known of the genus, of which no less than nine are 

 found within our limits, the rest being Andean species occurring in various places as 

 far south as the province of Yungasin Bolivia, whence we have lately received the 

 species described as C. mentalisf, and where also C. dryas occurs. Though none of the 

 species appear to occur at or near the sea-level, some (such as C. fuscater, C. mexicanus,
