The accompanying cut, drawn from a fresh specimen of B. virgniiaiius^ explains the form and position of the os prominens. It will be noticed that it is situated on the anterior surface of the distal end of the radius, and runs almost parallel with that bone, instead of standing erect as in the Balconidce. The radial portion of the tensor patagii longus terminates in the os promi- nens, and is not continued to the first metacarpal. Apart from the- Owls above noted, this bone has been found in Otogyps calviis^ Hctcrospizias meridioualis^ Buteo melano- IciicHS^ B. peiiiisylvaiiicus^ B. lineatus^ Circus gould/\ Ast?i- rina pucheratn^ and Haliivctiis Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Nuttall Ornithological Club.
