In the Vienna Museum there are, besides a large snite from Sonth-Eastern 

 Bra-Ml, an immature male from Borba (March 3, 1830) and an adult male from 

 Marabitauas, Rio Negro (April 4, 1831). These three skins agrte, in colour and 

 size, with topotypes from Cayenne. Birds from Southern Brazil (Bahia, liio, Sao 

 I'aulo, Parana) are somewhat lighter above, especially the cap paler and less sooty, 

 and the bill is, as a rule, horn-colour instead of black. They are entitled to the 

 name M.ferox cuntans Pelz.*

In addition, I have examined in the Vienna Museum an adult male obtained 

 by Natterer at Borba, March 1, 1830, which had been overlooked by Pelzeln in his 

 report. Both represent typical tuberculifer as defined by me {I.e.).

An adult male from Borba, obtained by Natterer in August 1830, belonging to 

 the Vienna Museum, agre.^s with a male from Quonja, Brit. Guiana, October 12, 

 1887 (H. Whitely coll., Mus. H. v. Berlepsch), in the coloration of the lower parts : 

 throat and under tail-coverts clear yellow, breast pale cinereous, middle of the 

 abdomen very pale yellowish ; but it has the grey of the nape slightly mixed with 

 olive-green, and the rectrices more conspicuously tipped with yellowish white. A 

 female from Cussary, a village on the south bank of the Amazons opposite Monte 

 Alegre, is exactly like the one from Borba except in having the nape olive-green 

 like pileum and back, without any grey. Its very dark, nearly blarkisli, bill seems 

 to be a sign of immaturity. 



The two males from Salto (iirao, farther up the Rio Madeira, and Engenho do 

 (tama, on the Rio (jnapore, in the Vienna Museum, have the cinereous breast 

 distinctly washed with pale yellow, the abdomen brighter yellow, and the bill
