b Of the four species recognized, I have only seen T'. Jloreola (the ty]De) from which 

 the above diagnosis is drawn up.

Since the preceding was Avritten this species has been placed in the genus Srrpn- 

 phaga by Hellmayr {Serpophaga caudata HelhnajT, Novit. Zool., xiii, 190(5, 323).

 rico); Orn. du Perou, ii, 1884, 250; Sclater, Cat. Birds Brit. Mus., xiv, 1888, 121. 



The original description of this species answers very well for Leptopogon flavovircns 

 Lawrence, and I suspect it may be the same.
