American Isthmu,? rlown to the Panama ralhvay-line. We have received specimens fn-m 

 Costa Eica and Veragua, and a considerable series from Panama collected by ]\Iesf4rs. 

 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.
