American Isthmus down to the Panama railway-line. We have received specimens from 

 Costa Eica and Veragua, and a considerable series from Panama collected by Messrs. 

 McCleannan and Hughes. In the adult Panama birds, the rufous of the tail is particularly 

 bright, and the black bars well defined ; and the cinereous breast is rather more pure than in 

 Guatemalan examples. Our principal figure is taken from one of these Panama specimens 

 in the collection of Messrs. Salvin and Godman. The younger bird, represented in the back- 

 ground, was obtained by Salvin on the southern slope of the Volcan de Fuego in Guatemala.
