I doubt much the real distinctness of this bird from Turdus grayii. 

 I have a specimen, believed to be from Guatemala, which agrees 

 nearly with Prince Bonaparte's type in the British Museum, It only 

 differs from the preceding in having rather smaller dimensions and 

 paler colouring, particularly beneath. I am not acquainted with 

 Planesticus luridus, Bp. (Compt. Rend, xxxviii. p. 4 ; Notes Orn. 

 p. 28), said to be from New Granada; but from the characters* 

 assigned to it, I should imagine it to be the same as the present.

I have once had the type of this species in my hand. My im- 

 pression was that it was nearly allied to Turdus ferrugineus ; bu.t I had 

 no means of comparison.
