« Chloronerpes rubiginosus tobagensis Ridgway, Proc. Biol. Soc. Wash., xxiv, Feb. 24, 

 1911, 33 (Tobago; coll. U. S. Nat. Mus.). 



b Chloronerpes chrysogaster Berlepsch and Stolzmann, Proc. Zool. Soc. Lond., vol. 2, 

 pt. 1, Oct., 1902, 32 (Garita del Sol and La Gloria, central Peru; coll. Branicki Mus.). 



Of this very strongly characterized form, the U. S. National Museum possesses a 

 fine adult male from Yitoc, Garita del Sol. If not a distinct species it certainly is 

 the most distinct of all the forms of C. rubiginosus. 



c Chloronerpes gularis Hargitt, Ibis, sixth ser., i, no. 2, April, 1889, 230 (Santa Elena, 

 Antioquia, Colombia); Cat. Birds Brit. Mus., xviii, 1890, 86. — (?) Chloronerpes rubri- 

 piZeus Salvador! and Festa, Boll. Mus. Zool., etc., Torino, xv, no. 368, Feb. 19, 1900, 14 

 (Foreste del Rio Peripa, w. Ecuador; coll. Turin Mus.). 



The U. S. National Museum possesses an adult male of a Chloronerpes from Guaya- 

 quil, western Ecuador, which seems to be C. rubripileus of Salvador! and Festa. It 

 has the entire pileum crimson, the malar patches crimson, and the tliroat spotted with 

 black and white. It is e"vidently closely related to C. gularis Hargitt, but the speci- 

 men in question is in badly abraded plumage, and therefore a satisfactory comparison 

 can not be made, especially since the only examples examined of C. gularis are two 

 females, one of them a young bird.
