able variation, hardly two specimens being alilve ; the same may be 

 said of the extent of the same colour. (-1) The black band varies very 

 much in width, both it and the extent of the fulvous depending very 

 much upon the way in which the skin is made up, and hence a cha- 

 racter of doubtful value; two of the Veraguan specimens have 

 scarcely any band, while the third has abroad one. (5) Guatemalan 

 specimens are in general of a clearer cinereous colour below ; Costa 

 liican specimens hardly so much ; Veraguan specimens are two of 

 them tinged with fulvous, and one almost as cinereous as Guatemala 

 skins ; both the male Panama specimens arc quite like the Guate- 

 malan. (6) The crissum of the Veraguan specimens is slightly darker 

 than Guatemalan, not so the Panama. 



The fact of the matter is, that wherever Saltator magno'ides is 

 found it varies in some degree as regards a few minor points. If aS*. 

 intermedius were admitted to rank as a species, we should have a 

 number of specimens which might with equal propriety be assigned 

 to either. None of our northern specimens have the sexes marked 

 so that I can depend upon them ; hence the question as to the dis- 

 tinction between the sexes cannot be discussed.

At Panama the southern form of this Finch ((?. cyatioides, Lafr.) 

 occurs, showing that the Central American race has its range sharply 

 defined, the present locality being its southernmost limit.

A single specimen from this locality agrees accurately with our 

 Guatemalan examples of O.funereiis and with Sclater's type. Ac- 

 cording to Mr. Lawrence the species of this form occurring on the 

 Panama Railway is 0. ccthiops, Scl.
