 series of topotypes differs in color from Schlegel's very good figure as 

 follows: Tawny of the underparts deeper and darker, nearly like 

 Ridgway's tawny; no pronounced black stripe bordering the tawny, 

 the tawny merel}^ much darker with the basal half of the hairs black- 

 ish; shoulder slightly more yellowish than in the figure.
