No " key to the species " of this genus can be drawn up, as there is no difference between them, except that of size, and the way in which one form graduates into another is shown by Mr. Salvin in his illustration of the heads of this species (Trans. Zool. Soc. ). I must confess that I am not entirely satisfied with regard to the changes of plumage in the Galapagos Finches, nor do I believe that these will be properly understood until some naturalist resides on the islands for at least a year, discovers the breeding-haunts of the various species, and traces the development of the plumage from the nestling to the adult stage. My own belief is that there is a distinct winter or cold-weather (? rainy season) plumage, and that with the seasonal plumage the colour of the bill changes. This would corre- spond with the changes undergone by other Grosbeaks and Finches. Dr. Habel writes as follows (Trans. Zool. Soc. ix. p. 478) :â" The.
