tris and its representative forms (O. maximiliani, O. occidentalis, 

 and O. melas) by its black bill, which, as will be seen by the out- 

 line given, is also more robust than in O. crassirostris. 



There is a small white speculum, which does not extend onto the 

 outer web of the three outer primaries, and is concealed by the 

 greater coverts when in their natural position. On the under sur- 

 face of the wing the white extends barely half an inch beyond the 

 black under wing-coverts, and then passes into grey, and at the 

 extremities of the feathers into black.

MM. Jelski and Stolzmann first discovered the true habitat of 

 this curious Finch, which, through an error of the Naturalists of the 

 Voyage of the « Venus,' had been assigned to the Galapagos. 



Prof.^ Steere' s series contains a single skin obtained in Dec. 1872, 

 at Sorritos, in Western Peru. It is marked " male : eyes light 

 hazel." It agrees in every respect with an example from Tumbez 

 (Jelski) in Sclater's collection.

Of this recently described Finch, from the same district, Prof. 

 Steere likewise obtained a single example at Sorritos, in Dec. 1872. 

 It is marked "male: eyes hazel." The discovery of a typical 

 Hamophila (of which the six previously known species are entirely 

 confined to Central America) in "Western Peru is a fact of the highest 

 interest.

Of this peculiar Fringilline form Prof. Steere obtained four exam- 

 ples during his sojourn at Sorritos. 



5. Icterus grace-ann,e, Cassin. 



Icterus grace-annce, Tacz. P.Z.S. 1877, p. 323. 



Prof. Steere' s series contains two skins of this well-marked Icterus, 

 described in 1867 by the late Mr. Cassin, from a single specimen in 

 the museum of the Academy of Philadelphia, of which the exact 

 locality was uncertain. The western sea- board of Ecuador and Peru, 

 however, is its undoubted habitat, as the late Prof. James Orton
