 species. Strangely enough, they had been determined by Salvin as

C. urochrysa is, according to our actual knowledge, confined to 

 the dense forests along the Pacific coast of N.W. Ecuador and 

 W. Colombia *. It is particularly common in the lowlands, 

 though Salmon also procured examples near Remedios, at 2300 

 feet elevation. 



At higher altitudes, however, in the Western Cordillera another 

 species of Chalyhura occurs, specimens of which were obtained 

 at Rio Dagua t by Rosenberg, and at NaranjoJ by E. Andre. 

 It agrees with C. buffoni from Bogota, in the coloration of the 

 tail (rectrices bluish black, more or less edged with bronze green) 

 and lower parts, but has the lower mandible mostly pale 

 brownish, like C urochrysa. "With only a single example before 

 me I refrain, however, from naming this ajjparently undescribed 

 form.

This buxl fully agrees with Bogota skins except that the green 

 tip to the inner web of the outermost rectrix is a trifle longer. 

 Ecviadorian specimens have much broader green tips to the lateral 

 rectrices, and the buff poi'tions of the tail as well as the under 

 tail-coverts are deeper in tint. They have been separated by Mr. 

 Oberholser as B. f. tinochlora §.

* The original locality " Panama " is open to doubt. Warscewicz was very 

 careless about labelling, and, moreover, not one of the many later travellers met 

 with the species on the Isthmus.
