The drawing of Aquila Culleni has been inspected and corrected by 
Professor Vanden-Nest, so that our figure may be taken as an exact portrait 
of the bird in the Antwerp Zoological Gardens. We also give details of 
wing, foot, and head, furnished by the Professor, who adds the following 
note to his previous remarks: — "One more word about the Aquila Culleni, 
after having collected all our remembrances. We have never had so fine 
an Eagle; its carriage is quite different from that of the Aigle ncevioides, 
the head is more degagee, in short it has a more noble air. It is even 
more degagee than the Imperial or Royal Eagles." 
In the above engravings the head shows the exact shape and situation 
of the nostril, and the extent of the gape beyond the eye. The wing shows 
the relative length of the primaries, and that the seventh is not notched 
like the others; the length of the longest primary, from the shoulder of the 
notch to the tip, is seven inches and one tenth. The foot shows the relative 
position and number of large and small scales.
