 E. eristata (Brit. Guiana). 



E. E. flavogaster dictae coloribus persimilis sed cristae plumis 

 valde elongatis, cristam densam in pileo medio forinantibus, 

 obscure brmmeis concoloribus, nee albo varus, nee non alis 

 caudaque brevioribus facile distinguenda. 



Al. 70-66, caud. 63-52 mm. 



Habitat : Cayenne (Cherrie leg., Mus. Tring) . Brit. Guiana : 

 Roraima and Merumé Mts. (Whitely). Orinoco : Altagracia 

 Quiribana de Caicara, Savannali, 16th April nesting (Cherrie), 

 Ciudad Bolivar (Klages) . Brazil : Bahia [Mus. H. v. B. ; 

 many specimens], Cidade de Goiaz (batterer), Lavrinhas 

 (Beim). C. E. Peru : Sta. Ana (Kalinowski). 



This species is easily known by its long uniform dark brown 

 crest, and its short wings and tail. The bill, as a rule, is 

 stronger and longer, and less curved. I have not seen addi- 

 tional specimens from British Guiana, which are perhaps to be 

 separated (cf. Omis. I.e.).
