The upper part oi the head and body fuscous ; the wing and tail darker ; the
throat, and beneath the body cinereous white, tinged with straw-colour;
the hill pale yellowish fuscous, and the feet fuscous.
Habitat, Galapagos Archipelago, (James’Island.)
The species of Camarhynchus do not differ in habits from those of Geospiza ;
and the C. psittaculus might often be seen mingled in considerable numbers in the
same flock with the latter. Mr. Bynoe procured a blackish specimen, which,
doubtless, was an old male ; I saw seyeral somewhat dusky, especially about
the head.
