The various remains of the present species already discovered 
belonged to five individuals, which differed but little in size, or 
in any important particulars. Taking the great Northern Diver 
(Colymbus torquatus Briin.) as a standard of comparison for the 
portions that are wanting, the skeleton of Hesperornis regalis 
would measure about five feet and nine inches from the apex

; its general features this humerus resembles that of the 
common Cormorant (Graculus carbo Linn.), although indicating 
4 somewhat smaller species. The articular head i ch more 
compressed transversely, its apex is more prominent, and its 
anconal margin is strongly deflected. The median ridge, on 
the anconal side below the head, is rounded instead of angular, 
and the ulnar crest is much less produced distally.
