natural affinity, but probably very distinct from that bird, even 

 in its generic situation. 



The bird here described as Timalia Thoracica, Horsf., is 

 the Timalia Pileata of that naturalist ; the reference to the PI. 

 Col., as belonging to the Pitta Thoracica, may be cancelled. 



403. The generic name of Grallaria, judiciously given to the Corvus 

 Grallarius by M.Vieillot, appears perfectly unobjectionable, and 

 renders the subsequent alteration of M. Boie unnecessary. 

 Myrmothera, as M. Temminck observes, is but a plagiarism of 

 lUiger's original designation Myiothera ; but the whole of this

 Saxicola.

 this bird possesess all the leading characteristics of our genus 

 Petroica, Another species has been placed by Mr. Vigors 

 among the genuine Fly-catchers. 



442. Sylvia Galactotes. The characters of this highly interesting bird 

 accord more with opetiorphynchos than with any other. It
