Eab. Nicaragua, Los Sabalos (Nuiting ^°) ; Costa Eica, Angostura (Carmiol'^), Rio 

 Sucio (J". Cooper ^^), Jimenez {Zeledon ^^j, San Carlos {JBoucard i^) ; Panama, Mina 

 de Chorcha ^, Calovevora ^, Calobre ^, Santiago de Veraguas ' , Santa Fe ^ {Arcs), 

 Lion Hill (M^Leannan ^ ^). — South America, from Colombia ^ to Peru, Amazons 

 Valley, and Guiana ^ ^. 



A species of wide range, extending over the whole of the Amazons Valley, and 

 thence northwards to the Caribbean Sea, and westwards to Panama, where it enters the 

 isthmus, and spreads through Central America as far as Nicaragua. Here Mr. Nutting 

 met with it at Los Sabalos and obtained two specimens ^<'- These, with others from 

 Costa Rica and Panama, Mr. Ridgway proposed to separate from the bird of Guiana 

 under the name of C. lineatus fasciatus ^^. Our series of specimens does not show any 

 grounds for this suggestion, for both males and females from Central America can be 

 exactly matched by others from Guiana and other parts of the southern range of the 

 species. Individuals vary in the width of the white bands, both of the upper and 

 under surfaces of the body ; but this variation is to be found everywhere, and we have 

 no doubt is due to the age of the birds, those with narrower bands being the older. 

 In some examples the crown of the head also shows transverse bands, but in general 

 the crown is pure black. 



C. lineatus was first described in 1815 by Leach i, who placed it in the genus iamews. 

 It was transferred by Vieillot to Thamnophilus, and to Cymbilanius by Gray ^, where 

 it remained a monotype without a synonym till Mr. Ridgway's attempt to divide it a 

 few years ago. 



Little has been recorded of the habits of this bird. Mr. Nutting says that it has a 

 clear note, but without variation, and that its iris is red i". The latter character it 

 shares with the larger Thamnophili, such as T. transandeanus. It appears to be an 

 inhabitant of the dense tropical forest, wherever that is found within the limits of its 

 range. Its food, according to Salmon, consists of insects ^.
