for here they find, by scratching in the cindery soil with their powerful beaks and
claws, the seeds of grasses and other plants, which rapidly spring up during the
short rainy season, and as rapidly disappear. They often eat small portions of
the succulent leaves of the Opuntia Galapageia, probably for the sake of the
moisture contained in them : in this dry climate the birds suffer much from the
want of water, and these finches, as well as others, daily crowd round the small
and scanty wells, which are found on some of the islands. I seldom, however,
saw these birds in the upper and damp region, which supports a thriving vegetation
; excepting on the cleared and cultivated fields near the houses in Charles
Island, where, as I was informed by the colonists, they do much injury by digging
up roots and seeds from a depth of even six inches.

I have strong reasons for believing this species is not found in James’s
Island. Mr. Gould considers the G. magnirostris as the type of the genus.
