bill at base, 0.30; tarsus, 0.75; middle toe, 0.53. (Type in Dr. Baur's 

 collection.) 



J^ange. — Galapagos Archipelago: Tower Island (Baur and Adams). 



The form of the bill in this species is conspicuously unlike that of 

 any other, being almost exactly that of CardueUs. 



There are 7 specimens in Dr. Baur's collection, 4 of which are in the 

 black plumage.

 the maxillary tomium slightly toothed.

 0.55; wing, 2.G5; tail, 1.45; tarsus, 0.75.
