John Gould was grateful for his assistance: -The greater number of the birds from which the following characters are taken are from the collection made by the officers of Her Majesty's ship the Beagle. To Captain Wickham and the other officers of that vessel I am indebted for much kindness and attention. By the exertions of Mr. Bynoe, surgeon of the Beagle, science has been enriched, not only by the discovery of these new species of birds but of several others and some quadrupeds of a most interesting description, the whole of which have been placed in my hands for the purpose of describing figuring etc. -
