  • "'In the frigate-bird the symphysis of the furcula coalesces with the carina and the upper end of each ramus with the caracoid, while in turn each caracoid coalesces with the proximal end of the scapula! ... I believe this to be unique among existing birds, and closely related to the creature's flight.'"
