Myrmeciza lencaspis Sclater, P. Z. S. 1854, p. 253, pi. Ixx. 

 (1855.— Bogota, Colombia (type); Ohamicuros, East. Peru; 

 Cobati, Rio Negro). 



Pithys leibcaspis Sclater & Salvin, P. Z. S. 1867, p. 576 (Cobati) ;

Gyninojnthys leucaspis Salvin & Godman, Biologia, Aves, ii. 

 p. 222 (Rio Meta, East. Colombia). 



This species is exclusively found in the forests of Upper 

 Amazonia, from the eastern slopes of the Colombian Andes 

 south to Northern Peru. Both Natterer and "Wallace obtained it 

 on the banks of the Rio Negro, while Wheeler transmitted specimens 

 from the Rio Meta, E. Colombia, to the British Museum. Haux- 

 well met with it at Chamicuros, Eastern Peru, and E. Bartlett 

 procured a series at Chyavetas, Xeberos, and Chamicuros, now in 

 the Tring Museum. A. leucaspis is also occasionally found in 

 the trade-collections sent from Bogota to Europe, 



Against the statement in the ' Cat. of Birds,' xv. p. 295, I wish 

 once more to emphasize that it is the fem.cde which possesses the 

 cinnamomeous interscapular blotch. Five sexed males from 

 Northern Peru (Chamicuros, Chyavetas, Xeberos ; Bartlett coll.) 

 in Mr. Rothschild's collection, five from the Rio Negro, obtained 

 by Natterer, in the Vienna Museum, and one male from Cobati, 

 R. Negro, Wallace coll. in the British Museum, show no trace of 

 it ; while in five sexed females from the Rio Negro (Natterer ; 

 Vienna Museum) there is a large conspicuous pa.tch at the base 

 of the dorsal feathers. Besides the above, I have examined two 

 males and four females from " Bogota-coll." in the collections at 

 Tring, Munich, and Paris. 



(2) Anoplops bicolor iEQUAxoRiALis Hellm. 



Pithys bicolor cequatorialis Hellmayr, Oi-n. Monatsber. x. p. 33 

 (1902."-Lita, N.W. Ecuador). 



P. leucaspis (nee Sclater) Hartert, Nov. Zool. v. 1898, p. 493 

 (Chimbo, W. Ecuador); Goodfellow, Ibis, 1902, p. 65 (Sto. 

 Domingo, W. Ecuador). 



Gyninopithys ruficeps (nee Salvin & Godman) Salvadori & Festa, 

 Boll. Mus. Zool. Torino, xiv. no. 362, 1899, p. 32 (Santiago, 

 W. Ecuador); Hartert, Nov. Zool. ix. 1902, p. 613 (Chimbo, 

 Paramba, S. Javier, W. Ecuador). 



This form, which is confined to Western Ecuador, shares with 

 A. leucaspis the bright ferruginous colour of the forehead and 

 crown, but is much darker rufous brown on the back, has the 

 sides of the occiput dark cinereous, etc., etc. I have examined 

 twenty specimens from "W. Ecuador in the Tring, Vienna, and 

 Munich Museums. There is never any triice of a pale inter- 

 scapular patch.
