' This figure was drawn from a dry specimen, parts of which had shown a tendency to separate ; and the gaps had 

 consequently been filled up with gum. In consequence of this the syzygy between the first two brachials of the middle 

 ray was wrongly drawn as a muscular joint- like that between the second and third brachials. It should have been 

 represented as a simple line without any gap between the joints, like the syzygies in the remaining part of the arm.
